Extraction Of Copper From Copper Pyrites Cufes2

Copper is extracted from its principal ore copper pyrites CuFeS 2. The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S O 2----- SO 2 4AS 3O 2----- 2AS 2 O 3 2.

Copper Extraction And Purification Chemguide

Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite also known as copper pyrites and similar sulphide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining.

Us7846233b2 Leaching Process For Copper Concentrates

A method of leaching copper from copper sulphide-containing concentrates, such as chalcopyrite, includes using pyrite as a catalyst for ferric reduction in order to eliminate passivation of the chalcopyrite surface, the process being carried out under conditions whereby the pyrite is not materially oxidized, for example by maintaining the operating solution potential at a suitable level.

Pyrite Roasting An Alternative To Sulphur

Pyrite roasting and sulphur burning plants are built for the production of sulphuric acid. Whereas the burning of elemental sulphur is the main source for sulphuric acid, the roasting process is an interesting alternative once pyrite concentrate is available. In addition to these two applications, Figure 1 shows a wider variety of sources for the
