In the second step of the production process, we convert the ore from a low-grade material into a concentrate of high-grade copper inside the Concentrator Complex. The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells. When mixed with water, reagents, and air, the copper minerals produce a bubbly froth.

The 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.
