• 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.

  • Froth Floatation Process

    Froth Floatation Process. This method is used for concentration of sulphide ores of copper, lead and zinc. In this method, powdered ore is put in a tank full of water. And then, some Pine oil is added to it. In the tank the particles of sulphide ore are wetted by pine oil whereas the gangue particles are wetted bywater.

  • pH Control in Copper Flotation for Maximized Product Yield

    Copper ore may be separated from crude ore using a flotation pro­cess that takes advantage of the physical (as opposed to chemical) properties of small copper ore particles. To maximize the copper yield, pH control is necessary in the flotation tanks. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.
