What are the three stages involved in extracting metal ,, 1 Concentration of the or 2 Converting the concentrated ore to its oxide 3 Extracting the metal from its oxide 4 Purification of the metalExtraction of Metals from Concentrated Ore: Reduction of ,, Extraction of Metals Now we already saw how the ore of a metal is concentrated to remove impurities known as gangue After concentration of ores, we must now extract metal from in it This step will give us metal in its pure form ie the native form of metal First, we must convert the ore to a suitable formExtraction of metal values from ores or concentrates ,, A process is described for leaching ores or concentrates containing one or more metallic sulphides with a circulating liquor so as to solubilize desired metal values therefrom, if said metal values are capable of dissolution in an acidic ferric sulphate solution (eg copper), or so as to render the desired metal values (eg gold) more accessible to subsequent processing, in each case by ,Environmental Aspects of Metal Extraction | Study, While extracting can refer to removing the ore or removing a mineral that contains a metal from the earth, it also can refer to removing the metal from the ore Take a moment to review the table ,21 Hydrometallurgy, For a high degree of metal extraction from an ore, the dissolution of the value metals must be as complete as possible, which is the primary consideration in the implementation of any leaching operation Any valuable metal that remains unreacted in the ore, after leaching, constitutes a loss of the metal (Woollacott & Eric, 1994:329).

SOLVENT EXTRACTION/ ION EXCHANGE FOR METAL ,, recovery of valuable metals by SX is also mentioned EXTRACTION OF METALS ON COMMERCIAL SCALE Copper : The solvent extraction process has been used for the production of copper first time in 1964 from dilute leach solutions containing low metallic values obtained during processing of low grade orStages of Hydrometallurgical Processes, slurried with the extraction fluid for a period of time When equilibrium between the metal on the soils surface and the metal contained by the solution is approached, the solubilization of the metal in the soil is slowed, and the extraction is considered to be complete [10] 11 Process StagesExtraction of Iron | Metallurgy | Blast Furnace and Reactions, The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state505 EXTRACTION OF METALS, The process of extraction of metal from the concentrated ore depends upon the nature of the ore as well as the nature of impurities present in the ore Before the concentrated ore is subjected to final metallurgical operations in order to get the metal in the free ,Biomining: metal recovery from ores with microorganisms, Up to now, biomining has merely been used as a procedure in the processing of sulfide ores and uranium ore, but laboratory and pilot procedures already exist for the processing of silicate and oxide ores (eg, laterites), for leaching of processing residues or mine waste dumps (mine tailings), as well as for the extraction of metals from ,.
