Overview | Copper Mountain Mining Corporation
The Copper Mountain mine is a conventional open pit, truck and shovel operation. The mine has a 40 ktpd plant that utilizes a conventional crushing, grinding and flotation circuit to produce copper concentrates with gold and silver credits. Plant throughput is expected to increase to 45 ktpd with the installation of a third ball mill. With the plant expansion, average annual production is expected to increase to 120 million pounds of copper …
Sequential Selective Flotation Process Flowsheet
ORE TREATED: Sulphide ores of lead, copper and zinc are primarily treated. This flowsheet can also be applied to other ores wherein the separation of base metals or nonmetallic minerals may be desired. ADVANTAGES: The first flotation machine in a copper-lead-zinc separation would produce a copper-lead concentrate.

Gold is processed using a traditional carbon in pulp (CIP) process and the copper processing is completed using either solvent extraction (SX) and crystal plants for oxide heap leach ores, or a conventional flotation plant for sulphide ores.
Copper extraction - Wikipedia
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically …
