processingРIn the majority of cases the energy consumed in direct smelting or leaching of low grade ores would be so enormous as to make the cost prohibitive。РMineral processing reduces the bulk and weight of material which must be transported to the smelter,the lack of undesirable waste materials increases the smelter recovery.Р3 Main operationsРThere are two fundamental operations in mineral processing,namely the liberation of the valuable minerals from their waste gangue minerals, and separation of these values from the gangue.Р4 Mineral processing methodsР1. Separation dependent on optical and radioactive propertiesР2. Separation dependent on specific gravity differences. Р3. Separation utilizing the different surface properties of the minerals.Р4. Separation dependent on ic properties
