<p>To stand out from the crowd, mining machinery manufacturers have added new technology to their latest ADTs in addition to the newest low emissions engines. Volvo, for instance, won gold at the ball mill 2012 innovation awards for the on-board weighing system it designed as an option for its new F-Series ADTs.
Pine oils, cresylic acid, and long-chain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarification and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium, lead, selenium, magnesium, aluminum, cobalt, tin, nickel, tellurium, silver, gold, and palladium. A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining.
The system monitors the input of weight on the cone crusher machine from its full suspension pressure sensors, and relays this information to load software integrated into the machine's electronics. All transport loads are logged and displayed to the operator, as well as remotely through Volvo's CareTrack telematics system, allowing data such as tonnes transported per litre of fuel to be recorded.
Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals.
Converting the matte yields a high-grade “blister” copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into “anodes”, and sent to an electrolytic refinery for further impurity elimination.
Komatsu's latest Stage IIIB/Tier 4 Interim ADTs - the HM300-3 and that HM400-3 - also feature new technology. The Komatsu Traction Control System (K-TCS) automatically provides optimum traction when operating in soft ground conditions. As ground conditions worsen and tyre slippage is detected by speed sensors located on four wheels, automatic application of the inter-axle differential lock occurs. If tyre slippage continues to be detected, then four independent brakes can be applied to slipping wheels to regain traction.
Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting, charge material of copper concentrate mixed with a siliceous flux (often a low-grade copper ore) is heated in air to about 650°C (1200°F), eliminating 20 to 50 percent of the sulfur as sulfur dioxide (SO2). Portions of impurities such as antimony, arsenic, and lead are driven off, and some iron is converted to iron oxide. Roasters are either multiple hearth or fluidized bed; multiple hearth roasters accept moist concentrate, whereas fluidized bed roasters are fed finely ground material.
