Extraction of copper from copper pyrites (CuFeS2

Extraction of copper from copper pyrites (CuFeS2) The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. Smelting in extraction of copper The roasted ore mixed with silica as flux is heated in a blast furnace by a blast of hot air.

What is Solvent Extraction? (with pictures) wisegeek.com

Jun 17, 2019 · Solvent extraction is a method for separating a substance from one or more others by using a solvent. It relies on variations in the solubilities of different compounds in different substances. In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction — this is

What is Bioleaching? (with pictures) wisegeek.com

Jun 05, 2019 · Bioleaching is the use of bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded.As an alternative to smelting or roasting, miners use bioleaching when there are lower concentrations of metal in ore and they need an efficient, environmentally responsible method to extract it. The bacteria feeds on nutrients in minerals, thereby separating the
