To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is delivered to the crusher(s) to be reduced in size. At this stage, much of the moisture with the ore may be lost to evaporation and drainage because of climatic conditions, residence time in stockpiles, and the heat generated in the crusher. At

Although PCDs are low-grade, they are important because they can be mined at a low cost on a large scale. Flotation is a common mineral processing method used to produce copper concentrates from copper sulfide ores. In this method, copper sulfide minerals are concentrated in the froth while associated gangue minerals are separated as tailings.
