Wide Application
Chalcopyrite is the most important copper ore. Chalcopyrite ore occurs in a variety of ore types. It is present in volcanogenic massive sulfide ore deposits and sedimentary exhalative deposits, formed by deposition of copper during hydrothermal circulation. Chalcopyrite may also be found in coal seams associated with pyrite nodules, and as disseminations in carbonate sedimentary rocks.Chalcopyrite deposits are widespread across the globe, mainly inUSA, Japan, Mexico, South Africa, Nigeria, Zambia etc.
Chalcopyrite is a common mineral and is found in almost all sulfide deposit and is often disseminated through igneous rock. The chalcopyrite ore deposit will be first extracted by open pit quarrying or underground mining methods.
For lower grade deposit located near the surface, the open pit mining method is the most practical for the mining of large tonnages of chalcopyrite material. Large track mounted drill of ore is prepared for blasting and the broken ore is hauled to the ore dressing plant by truck or belt conveyor.The open pit copper mining plant has the benefits of relatively low cost-extraction ratio.
Some chalcopyrite ore deposit is very deep away from the earth surface. Usually, underground mining method will be applied. In underground mining, vertical shaft are sunk well over 1,000 meter below the surface and channels are extended to the ore body. The ore, broken by drilling and blasting is hoisted through the shaft and conveyed to the processing plant. In some cases, primary crushing takes place underground and in others, a ramp and trucks carry ore to the surface.
The first step in the chalcopyrite mining operation is to liberate the copper minerals and remove waste constituents such as alumina, limestone, pyrite and silica so that the copper and non-ferrous mineral values are concentrated into a productcontaining between 20 to 30 percent copper. The second step involves either smelting or leaching to remove a largeproportion of impurity particularly iron and in the case of sulfides ore, sulphur.

Chalcopyrite crushing is the primary stage in chalcopyrite mining operation. Due to it hard property, chalcopyrite crushing may be performed in two or threestages. Primary crushing systems consist of crushers, feeders, dust control systems, and conveyors used totransport ore to coarse ore storage.
Primary crushing is often accomplished by a jaw crusher or gyratory crusher,since these crushing equipment can handle larger piece of rocks.The feed to primary crushing machine is generallyrun-of-mine chalcopyriteore, which is reduced from large pieces to smaller pieces.Primary crushing systems are typically located near or in the pit at surface mines orbelow the surface in underground mines.
Primarily crushed chalcopyrite ore is then conveyed by belt conveyor to secondary crusher machines, which are usuallylocated near the next step in beneficiation. Secondary and tertiary crushing usually is performed in surface machinery by impact crusher or cone crushers.
SBM developed complete series of crusher machine for chalcopyrite mining plant, including jaw crusher, gyratory crusher, impact crusher, cone crusher, VSI crusher, mobile crusher etc. We also provide professional consulting service about crushing and screening machine installation, operation and maintenance.
