Crushing Ores And Smelting

Oct 09, 2020 Smelting. The extraction of the metals from the calcined or roasted ore consists of two steps i.e., removal of earthy impurities and reduction of the ore to metal. The different methods applied for carrying out the concentration of ores are useful to separate only a part of gangue and the ore still contains some earth impurities.
