Froth floatation method

Gold flotation The Froth Flotation Method is means separating minerals according to their different physical and chemical properties According to classification the flotability of gold and silver minerals is included in the first category of natural and nonferrous heavy metal sulfides characterized by low surface wettability and easy flotation which can be flotation by xanthate collectors
