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. The milling of copper ores as practiced in the larger
The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step, involving either smelting or leaching, removes a large proportion of impurity

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. A continuous process
The MK Gold Company is developing a complete commercial production system of this type for the processing of ores from the Las Cruces deposit with the planned annual capacity of 72 000 t of metallic copper. The process of leaching the iron-rich copper
There is a process that mining business projects have to go through before starting the operations. These steps are critical to follow through such as from the discovery of an ore body through the extraction of the ores
