removal of iron in extraction of copper

How Is Iron Extracted From the Earth?

How Is Iron Extracted From the Earth? , the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances .The primary objective was to maximize copper extraction using one solvent extraction circuit The role of feed acidity and the disposition of impurities such as iron and chloride are considered The challenges of running short , SX to remove all the copper in one step The primary extraction circuit takes the bulk of the copper, leaving a.

Mining of Iron Ores

The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)n(H2O)) or siderite (FeCO3) The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state It consists of several distinct stepsThe principle ore of copper is copper pyrite and copper is extracted from this ore The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized The ore being sulphide ore is concentrated by froth floatation process.
