OverviewFroth flotationHistoryConcentrationHydrometallurgical extractionSulfide smeltingConcentrate and copper marketingSee also

The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat. All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachatesolution, but this is a m

Copper Cementation System for Small Scale Mining

Plants producing 10 and 50 tons of cement copper per day were evaluated as typical small and intermediate-size operations. The comparison of these cementation procedures was based only on the cementation and dewatering steps. Costs were estimated on the basis of requirements for constructing and operating these units, including their proportionate share of the plant utilities and facilities ...

Agitated Copper Leaching Cementation Process

Copper Agitated Leaching and cementation process of copper problem: The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations.

Definitions - International Copper Study Group

Cement copper (precipitated copper) is a product obtained by precipitation (cementation), i.e., by adding iron to the aqueous solution resulting from the leaching of certain ores or waste. It is a finely devised black powder containing oxides and insoluble impurities. Cement copper is often added to the charge which goes to a converting furnace to produce copper matte.
