flotation of mixed copper ore

Copper The Essential Chemical Industry

(a) Concentration of the ore. The ore is enriched by froth flotation (Figure 4). The powdered ore is mixed with oil and agitated with water in a large tank to which detergent has been added. Compressed air is forced through the mixture, and the lightweight particles of copper sulfide are carried to the top and float on the froth.
