Gold Copper Mining Project Brief Introduction
The Cadia Valley Province is well-known for its richness in mineral. The Ridgeway underground mine is situated in this province in central New South Wales. Owned by Australia’s Newcrest Mining, it started the gold copper mining project since April 2002. Ridgeway mine is a sub-level caving operation, focusing on trasitionning to a block cave.
Australia continued as the world’s third-largest producer of minerals and metals. Its mineral industry, flourishing in all six states and the Northern Territory, served as a leading catalyst for the economy, which grew 4% in 2000. The country had the world’s largest economic demonstrated resources (EDR) of lead, mineral sands, nickel, silver, tantalum, uranium, and zinc, and its EDR ranked in the top six for bauxite, black coal, brown coal, cobalt, copper, gem and near-gem diamonds, gold, iron ore, lithium, manganese ore, rare-earth oxides, and vanadium. The country is virtually self-sufficient in mineral commodities, commercially producing more than 60 minerals and metals. Successful exploration in the late 1960s led to a long-term mineral boom and a sharp increase in exports. Australia is the world’s leading exporter of alumina, bauxite, coal, diamond, ilmenite, iron ore (the country’s fourth-largest minerals earner), refined lead, rutile, and zircon. Export earnings increased to about $9.46 billion in the fourth quarter of 2000, a 42% increase over the same period in 1999.
Gold production in 2000 was 296,410 kg, a 4% decrease from 1999. Gold accounted for $2.73 billion of the country’s $30.56 billion in total mineral export value, and reserves were estimated at 5,018 tons. Western Australia produced 75% of the country’s 300 ton per year output. The largest producer in 2000 was Australian Gold Refineries, whose Perth Refinery, at Newburn, had an annual capacity of 95,000 kg and whose Kalgoorlie Refinery had an annual capacity of 46,000 kg. A feasibility study for the Granny Smith Mine anticipated about 10 tons of gold during the 6-year life of the opencut operation beginning in 2002. Mining also began in 2000 at the Carosue Dam opencut mine, with production planned at 3.4 to 4.4 tons per year of gold during a mine life of 8 to 10 years. In 2000, the country was the world’s leading producer of alumina, bauxite (for the 30th consecutive year), chrysoprase, ilmenite, mined lead, precious opal, rutile, and zircon; ranked second in iron ore (with 15% of world production), mined cobalt, and mined zinc; ranked third in mined gold (with 10% of the world’s output) and mined nickel; and was fourth in mined copper. Metallic minerals contributed 40% of the country’s $25 billion in mineral and energy production in 2000, and industrial minerals contributed another 5%.
The country produced 830,000 tons of contained copper in 2000, a 12% increase from 1999 and up from 560,000 in 1997. Reserves were estimated to be 22.2 million tons. WMC’s Olympic Dam underground mine, in South Australia, was the country’s largest copper mine, and a $1.1 billion expansion program was expected to increase production from 200,000 tons per year to 245,000. Production of gold and silver at the mine in 1999 was 2,426 kg and 26,438 kg, respectively.

Explosions in Cement Plants
Cement Plants
• Cement manufacturing is one of the largest mineral commodity industries in the United States, with an estimated production capacity of greater than 73 million metric tons annually.
• Essentially the heart and soul of the cement manufacturing process, the kiln is a horizontal steel cylinder, lined with firebrick and sloped slightly downward, from the raw material feed to the fuel feed supply and burner pipe. Typically, kilns will rotate at one to three revolutions per minute, heating the raw material mix to a red-hot, 2,500-plus degree molten form that emerges from the lower end of the kiln in the form of very hot, marble-sized chunks known as “clinker”. Once out of the kiln, the clinker goes through a cooling process. When cool, the clinker is ready to pass through a series of grinding and milling processes that result in the gray powder we know as cement.
• The cement industry is very capital intensive. Some of the major pieces of equipment include pulverizers, dust collectors, electrostatic precipitators, and rotary kilns.
• Energy costs can account for up to 40 percent of the total cost of cement manufacturing. Currently, over 90 percent of the installed capacity uses coal as the primary fuel. Conversion to coal was started in the 1970’s. In 1972, only 39 percent of the industry’s energy was supplied by coal.
• Inland Cement, “We are also concerned about the potential fire and explosion hazard of working with coal and are confident that we can use coal safely. Coal has been the fuel of choice for the cement industry around the world for many years and the technology is well developed to prevent fires and explosions.”

Explosions in Cement Plants
• Coal is fed into a pulverizer where it is crushed and dried using hot air at approximately 300°F. The pulverized coal is then pneumatically transported to the dust collector where the pulverized coal is collected and either fed directly to the burner at the kiln or to a storage bin.
• During normal operation the coal stream is inerted with nitrogen or similar gas. The problem typically occurs during startup, shutdown or failure of the inerting system.
• It is not uncommon for tramp metal, railroad spikes, or similar metal objects to be fed into the grinder and thus create sparks. These sparks can travel from the pulverizer through the transport pipe and into the dust collector.
• Another source of ignition in the dust collector is static electricity. The atmosphere in the dust collector is typically at ~200°F with the dry coal dust suspended. These conditions increase the risk of explosions in the dust collector.
• The other common ignition source is pyrites that are collected below the pulverizing bed. If there is a failure of the inert gas source then air is introduced and the pyrites can ignite the coal dust.
• Coal is milled to a fine powder in a pulverizer – this increases the surface area of the coal and hence the rate of
combustion. The powdered coal is blown into the combustion chamber of the burner nozzle where it is burnt at around 1400°C.
• The Mine Safety and Health Administration (MSHA) a branch of U.S. Department of Labor reports that during the past 5 months, eight explosions have occurred, resulting in one fatality and nine nonfatal injuries. Six of these explosions
occurred in cement plants.
Cement Plant Equipment with Highest Explosion Potential
As reported by Factory Mutual, the following equipment have experienced losses of greater than $26,000,000 over the last ten years due to explosions. Coal dust explosions were the cause of twenty-seven losses. Forty-seven percent of kiln losses occurred in the cement industry. A typical plant layout of a coal burning cement plant is shown in the next diagram. The equipment shown in red are the ones most likely to have explosions and the need for explosion protection. Each of these pieces of equipment is described in greater detail in the remainder of the document.
EXPLOSION PROTECTION COAL PULVERIZER
Coal Pulverizer Functionality:
• Raw coal is fed into the coal inlet, dried and ground to a fine dust on the grinding table. Hot air (inert gas) is used to pneumatically carry the coal dust upward through the classifier and into the transport pipe.
Coal Pulverizer Explosion History:
• Loss history for the past ten years due to dust explosions from FM Global Data Sheet 7-76:
• Six in ball/hammer mills for a loss of $2,012,000.
• Ten in Pulverizer/Fragmentizers for a loss of $1,643,000.
Coal Pulverizer Sources of Ignition:
• Tramp metal, i.e. railroad spikes, and pyrites are a typical source for ignition.
• A loss history evaluation for a recent twelve year period indicates that a loss of inerting or not following inerting
procedures was a factor in all explosion incidents.
• Many explosion incidents resulted when proper isolation, clearing, or shutdown procedures were not followed.
• Half of all explosions occurred during a hot restart.
• Hot furnace gases backing up into the pulverizer system was responsible for several explosions.
Coal Pulverizer Solution:
• Explosion Venting of the pulverizer is not allowed per NFPA 8503 or FM 6-24/13-21, so this equipment is best
protected by either containment (tested to 200 psi), or an Explosion Suppression System. Chemical Isolation should be used on the inlet and outlet to prevent flame propagation to other equipment.

Sand Production Line
Ekati Diamond Mine, Northwest Territories, Canada
Ekati diamond mine, near Lac de Gras in Canada’s Northwest Territories, is about 300km north east of Yellowknife. It is a joint venture between BHP Billiton Diamonds Inc (80%) and geologists Charles E Fipke and Dr Stewart E Blusson (10% each), BHP Billiton having bought out Dia Met Minerals’ holding in mid-2001.
A 500km seasonal ice road is rebuilt every year by Robinson’s Trucking to supply the northern mining operations, including Ekati. The only other transport is by air from Yellowknife.
GEOLOGY AND RESERVES
Lac de Gras kimberlites are similar to those of South Africa and Russia, with all the kimberlite pipes being overlain by small lakes.
As of mid-2000, Ekati had proven and probable reserves of 60.3Mt at 0.9ct/t. By mid-2003, reserve addition through exploration had virtually equalled production to date, with reserves standing at 59.0Mt grading 1.0ct/t. As of end-2005, the measured open cut resource at Ekati (core and buffer) stood at 42.5Mt grading 0.8ct/t; the S/P resources at 2.6Mt with 2.6ct/t and underground ore at 6.8Mt at 1.5ct/t. The proved core reserves were 16.5Mt (0.4ct/t) open cut, 2.7Mt (1.4ct/t) S/P, and 3.4Mt (1.0ct/t) underground ore.
MINE PLAN
To date, 150 kimberlite bodies have been discovered within the project’s concession area, although most of these do not carry economic diamond concentrations. The current mining plan is focusing on open-pit mining from the Panda, Koala, Fox, Beartooth, Pigeon, Sable and Misery orebodies, with subsequent underground production from Panda and Koala. The project is expected to have a life of 25 years or beyond.
Open-pit mining started on the Panda pipe and Koala, Misery and Fox have subsequently been developed sequentially. Each lake is being drained and shovel-and-truck, open-pit mining developed, with some 35–40Mt/y of waste rock being excavated from the pits. The ore feeds a central 18,000t/d-capacity processing plant. The 3.4km Panda Diversion Channel diverts water around the Panda and Koala Lakes into Kodiak Lake.
Mining equipment includes four Driltech D90KS blasthole drills, two Demag H655SO diesel-hydraulic shovels, ten Caterpillar D10R bulldozers, a Cat 994 loader, a Cat 5120 hydraulic excavator, four Cat 992 loaders and other support equipment. 13 240t Cat haul trucks, three 170t Cat 793 haul trucks and 11 100t Cat 777D haul trucks carry waste and ore from the pits.
Canada mining equipment
DIAMOND RECOVERY
In the process plant, a gyratory primary crusher reduces ore to minus 300mm, coarse ore being stockpiled in a 20,000t-capacity storage building. A hot water-flushed cone crusher reduces the ore to 75mm before a high pressure roll crusher reduces it to minus 25mm. Primary and secondary scrubbers and degritting and sanding sections remove fine waste material for disposal. Heavy-medium separation (HMS) using slurried water and ground ferrosilicon separates a diamond concentrate from the crushed ore. Finally, X-ray fluorescence sorters are used to extract the diamonds from the HMS concentrate.
UNDERGROUND EXPANSION
Development of the US$182m Panda underground project should provide some 4.7 Mct/y over a six-year life from 4.6Mt of ore. The underground mine was completed early in 2006, on time, on budget and will produce around 2,600t/d of ore. Panda underground will provide around 40% of Ekati’s output by value.
In June 2006, BHP Billiton announced approval of a second underground mine, Koala, intended to contribute 3,300t/d of ore by mid-2009, following start-up late in 2007.
PRODUCTION, SALES AND MARKETING
In late 2002, BHP Billiton ended the agreement by which De Beers bought 35% of Ekati’s output, with the remaining 65% being marketed independently, and will now market all Ekati’s output. All mine production is sorted and valued at Yellowknife prior to shipment for sale.
The mine treated 5.6Mt of ore during 2003 to yield 6.96Mct of diamonds. The tonnage treated during 2004 was considerably lower, at 4.5Mt, and lower again in the year ending June 2006, when 4.3Mt ore was processed to yield 2.56Mct.
ENVIRONMENT
Environmental awareness is an integral part of staff training. Water use, waste management and land use and rehabilitation are carefully monitored. To date 314ha of tundra habitat have been used for construction of the mine and 611ha of the total lease area of 10,960ha has been affected by the operation. Rehabilitation is an on-going, long-term aim.

Double Toggle Jaw Crusher
Double Toggle jaw crusher Product Details
Double Toggle Jaw Crusher of our design have quite a few special features for continuous crushing the angle between the two Jaws has to be smaller than the angle of the nip. The lesser the angle between two Jaws than the angle of nip, the lesser the slippage between Jaws and materials, and hence less wear on Jaw plates. Theoretically parallel Jaws for example, when angle between two Jaws is zero would provide the ideal conditions with absolutely no slippage. Naturally with these types of Jaws no continuous crushing can take place. But one can do very close to this condition, by suitably designing the crusher mechanism.
Our design is reduce the slipping tendency to the bare minimum. Our Swing Jaw stock and the location of Hinge Pin point on the centre line of the crushing zone ensure that the motion of the Jaw plates is squarely against the material. The material is gripped and crushed immediately and there is no rubbing action. The running cost of the Jaw crusher replacement of the Jaw plate is expensive. Due to the above design features due to friction, the wear of our Jaw plate is minimized, so the Jaw plates last much longer which makes the crusher more economical.
Double Toggle Jaw Crusher Salient Feature
There are some additional special features also in this design:
The Pitman is light which enable the crusher to run faster, and naturally the through put is higher. The Pitman being light the crusher required less power and all this makes our crusher more economical.
The main body itself is light sturdy and fabricated construction. The Pitman, Toggles, Bearing Seats, Eccentric Shaft and the Main Bearing are all enclosed by dust sealed covers and are lubricated by continuous oil circulation.
The arrangement of Jaw setting is provided on Stationery Jaw stock side instead of Swing Jaw stock. There by, the geometric of the Toggles remains undisturbed by the variation in Jaw setting and the crusher can always work with maximum efficiency.
Another unique feature is safety device. Incase of accidental overloads the safety device disengage the driven pulley then runs only as a lose pulley. The machine is there by protected against damages.
Working Principals
The principals of crushing without rubbing is the secrets of “PICS INTERNATIONAL” product. That’s why the production is considerably higher then conventional crushers. The conventional types of jaw crusher s the stone pushed upwards, the stone rubs against the Jaw so the wear is fast; the capacity is low with heavy power consumption. The same is applicable to Single Toggle Jaw Crusher with further disadvantage of high upward pressure because the stone pushed up and down.
The motion of the Jaw plates is squarely against the rock. The center of Hinge Pin is passing through the center of the Crushing zone. The stone is gripped firmly and is crushed with the minimum rubbing action. It means less wear power and more production.
DOUBLE-TOGGLE STYLE JAW CRUSHER
In a double-toggle style of crusher the moving jaw plate’s pivot point is at the top. The moving jaw plate is typically referred to as the swing-jaw for that reason. The eccentric shaft is mounted separately from the swing-jaw and is located towards the bottom of the crusher. The eccentric motion is transferred to the lower part of the swing-jaw by the use of a shorter toggle plate. There are several major advantages to this arrangement:
• The horsepower requirement is substantially reduced and only one small diameter flywheel is used
• The eccentric, toggle plates, and shaft bearings run in an oil bath and are protected from dust and other contaminants
• The tramp-iron release mechanism is mounted on the much smaller flywheel and is easily reset
• The swing motion is in a straight line rather than elliptical and the manganese wear plates last longer
Over the years many mines have used the double-toggle style of crusher because of its ability to crush materials, including mineral bearing ores that were both tough and abrasive. While many aggregate producers have used the overhead eccentric style. There are many factors that should be considered when deciding which style would be best for your application.
A rotating shaft driven by either a diesel engine or an electric motor produces all jaw crusher s’ motion. To keep the motion as consistent as possible the overhead eccentric unit uses two large flywheels, one located at each end of the shaft. The weight of these flywheels produces inertia that helps even out the surges inherent in crushing material that is inconsistent in size and volume.
Double-toggle style jaw crusher manufacturers include Kue Ken, Kemko and Brown-Lennox (under license from Kue Ken), Birdsboro-Buchanan, Pennsylvania jaw crusher , Allis Chalmers, Superior, and Kobe Steel’s Allis Chalmers jaw crusher s.
