This is related as: 1) iron sulphide mineral levels are usually much higher than copper concentration, 2) sulphide flotation collectors can float iron sulphides well also, 3) liberation can be an issue making copper and iron separation difficult, and 4) fine particles are often more difficult to separate.
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors. Conclusion Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation.

Copper extraction - Wikipedia. Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value.
Alibaba.com offers 1,231 copper ore separation plant products. About 90% of these are mineral separator. A wide variety of copper ore separation plant options are available to you, such as gravity separator, flotation separator.
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
Separating minerals by flotation processes June 2014 ABB South . The flotation process can separate a desired mineral such as copper, nickel, molybdenum or zinc from ore.
Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and ...
11 Arsenic and associated copper minerals Arsenic occurs at varying levels in some copper ore bodies, and is a significant environmental hazard in the copper smelting process when emissions are released into the atmosphere.
