Solvent extraction is the latest separation technique and has become popular because of its elegance, simplicity and speed. Cu, Fe, Zn, Sn, etc.. are extracted by this method. The extraction involves 3 major steps (i) concentration of the ore (ii) isolation of the metal from it‘s concentrated ore (ii) purification of the meta The ores even after concentration contain some earthy matter called gangue which is heated combine with this earthy matter to form an easily fusible material. Unit IX: Coordination Compounds. Minerals: The natural substance in which the metals or their compounds occur in the earth is called minerals. The process of extracting metals from ores is known as Smelting. General principles of metallurgy. we hope you like it and if you have any query related to this section write us on comment box.
