Principles and Procedures involved in the Extraction of MetalsHow to Extract Precious Metals From Sulfides Sciencing

P rinciples of Metal Extraction Metals are found in the combined state in ores where they exist as positive ions During the extraction of metals the metallic ions must first be reduced to the corresponding metal atoms This reduction process can be done electrolytically or by thermal or chemical methodsThe most popular method of separation is the froth floatation method which was specifically designed for sulfides as opposed to smelting which is more suitable for larger veins of metal ore Another more modern method uses microorganisms to separate the metals from the sulfur
