BRITISH COLUMBIA 8211 Copper Mountain Mining Corp. of Vancouver has commissioned the new primary crusher and overland conveyor at its Copper Mountain project 15 km west of Princeton. Ore has been crushed and is stockpiled until the mill is commissioned, scheduled for May 2011.
Assembly of the second Komatsu PC 8000 hydraulic shovel has been completed and is being put into service. The two shovels are the main loading units for the mine. Only one of the 13 Komatsu 240-t haul trucks remains to be commissioned, and it should be ready by the end of April. The planned mining rate is 160,000 td.
Pre-production mining activities commenced in the Pit 3 area with the first shovel on the western wall, and the second in operation on the eastern wall push-back.
Construction activities within the concentrator are well advanced, says Copper Mountain, with most of the work being directed at completion of piping and electrical tasks. Installation of the grinding mills is progressing as planned with pressure testing of hydraulic lube lines and the installation of the SAG liners. The grinding mills are expected to be ready for testing by the end of April.
The Copper Mountain project currently has 520 workers on site, of which 240 are Copper Mountain personnel and the rest associated with the construction activities. At full production, the project will employ 271 personnel.
Pit Crushing And Coal Conyeing In Queensland . The existing in-pit crushing system will be retained at least until the present concentrator is shut down and during this period a new semi-mobile inpit crushing plant will be installed in the northern section of the open-pit, as well as a new crusher on the surface close to a stockpile feeding the 3.5-km overland conveyor to the new concentrator.
TNT designed, supplied and installed the worldrsquos largest mobile multiple-lift heap leach stacking system 7,200 sth in 2005-07 for a new copper mine in southeast Arizona, USA, and since then has supported its stacking operations with two expansion projects in 2011-12 and 2013-14. This mobile stacking system was surpassed as the worldrsquos largest in 2010 by TNTrsquos system at a copper mine in Chile.
TNTrsquos patented Super Portablereg technology allows fully independent movement of each piece of mobile conveying equipment on the stacking pad. The original system comprised a 370rsquo conveyor, a 7,400rsquo long regenerative overland tripper conveyor, ten 72rdquo x 250rsquo Super Portablereg conveyors, 108rsquo Horizontal Feed Conveyor, 285rsquo long Horizontal Conveyor and 190rsquo 220rsquo long Radial Stacker with 30rsquo telescoping stinger.

The designer of belt conveyors is often faced with problems of determining the proper belt speeds, belt widths, number of plies in the belt, and idler spacing for conveyors employed in various parts of a mill. Equipment Company offers the following data and tables, based upon many years of experience in designing all types of mills, to assist others concerned with mill design in engineering conveying systems. Graphs shown on the next page show belt conveyor capacities and horsepower requirements for various conditions.
To solve a conveyor problem, certain facts must first be known. This information is essential for sound conveyor engineering tonnage per hour, average size of material, maximum lump sizes, weight of material in pounds per cubic foot, conveyor pulley centers infeet, whether conveyor is to operate horizontally or on an incline 18 should be the maximum inclination and whether the application is to be as a feeder, picking belt, or for conveying crushed ore or concentrate.
In general, the number of plies and weight of belts as shown on table A on page 1 will be suitable for horizontal and inclined conveyors not over 300 feet pulley centers and transporting crushed ore. Where conveyors are extremely long or must convey unusually large and abrasive lumpy materials, Equipment Company engineers will gladly assist with conveying problems.
Properly engineered conveying systems can mean a material savings in both power and maintenance. A system should be adequate but not oversize to do the job intended. From the standpoint of initial cost, narrow belts are favored while slower speeds favor long life.

The effective tension on the belt is 33,000 times the total horsepower required at the head shaft, divided by the belt speed in feet per minute. The maximum tight side tension of the belt employing screw take-ups is the effective belt tension times 1.8 for bare pulley drive and times 1.66 for lagged pulley drives. Where a counter weighted type of take-up is employed, the maximum tight side tension is computed by multiplying the effective tension by 0.50 for bare pulley drive, and by 0.38 for lagged pulley drive.
The most popular drive is a motor-V-belt drive to a totally-enclosed running-in-oil torque arm speed reducer which is keyed to the head shaft of the conveyor. For a small additional cost an automatic backstop can be added to prevent an inclined conveyor from running backward during a power failure.
A less expensive drive is one employing one or several spur gear reductions between the head shaft and the counter shaft. A V-belt or roller chain drive is used to connect the motor with the counter shaft.
A third arrangement is a gearmotor-sprocket and roller chain drive to the head shaft, which makes for a very satisfactory and compact drive.
