The study evaluated implications of different ore grades and mine-depth on the energy inputs to extract and process copper. Based on a 191 value dataset from 28 copper mining operations, seven model equations explaining operational energy costs were statistically evaluated. Energy costs for copper mines with leaching operations were not …

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.

The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ∼50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978).Unlike the system for lead, the copper and Cu …

The ore from the deposits will be processed by a grinding circuit comprising two stages of crushing. The plant will use a bulk flotation circuit designed to produce separate copper and nickel concentrates. The circuit will feature bulk rougher flotation, regrinding, a two-stage bulk cleaning process, followed by copper and nickel separation.
