Part Four Competitiveness ... The costs of mining and processing copper are more closely related to the gross tonnage of the ore than the net tonnage of copper in the A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore. However, because the rich ore .
Coppercontaining rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue.
The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper .
One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper ... old car parts is used for this process. You may have to let the solution stand overnight or until the next laboratory period for the reaction to go to completion.
Ore Processing, Copper Mine Challenge Background The drilling rig for the blasting holes is operated by large chains. Dust, poor lubrication, and hydraulic oil contamination caused severe rusting of the chains. They became stiff and would not function properly.
Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or
