  • The influence of copper ore lithology on the grinding

    The influence of copper ore lithology on the grinding

    Oct 15, 2014 The main aim of laboratory tests was to find a relation between lithology of tested samples of ore and grinding media wear. Wear tests were performed in a laboratory mill filled with ball grinding media. Wet grinding was performed, which is typical for copper ore milling. Details of equipment used and tests data are presented Table 3.

    12.3 Primary Copper Smelting

    Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
