Raw, copper-bearing rocks went through three steps before it was the pure copper that the Quincy Mining Company could sell. T hese steps were mining, milling, and smelting. Mining was taking the rock with copper in it out of the earth. This was the first step. The second step was separating the copper from the rock. This is milling.
12.3 Primary Copper Smelting
steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 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.
