Copper Ore Processing Methods
Apr 11, 2017The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

3. Processing of Copper Ore
The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.

Grinding process summaryplanet
Centerless grinding is a high production process for continuously grinding surfaces in which the workpiece is supported not by centers or chucks, by a blade (figs. 16.1 a and b). Typical parts made by centerless grinding are roller bearings, piston pins, engine valves, camshafts, and similar components.

The influence of copper ore lithology on the grinding
Oct 15, 2014Wear is proportional to the energy dissipated in these zones. One of the most significant problems in the copper production industry is maintaining good efficiency of ore grinding and low cost of this process. The two key factors affecting the costs are the energy consumption and grinding media wear.

Energy efficiency • Energy intensity in copper and gold
In the production of copper, sulfidic ores are enriched into concentrates by grinding and flotation, followed by pyrometallurgical processes for the production of pure copper. Oxidic ores are treated with sulfuric acid in a heap leaching process after the grinding stage and are subsequently processed into cathode copper by SX/EW methods.
