2020-5-21Gold 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 non-ferrous heavy metal sulfides characteried by low surface wettability and easy flotation which can be flotation by xanthate collectors

2020-5-18Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form

These flotation reagents preferentially adsorb at the solidliquid interface making the surface of wanted minerals water repellent and facilitating bubble-particle attachment. They are classified based on composition and whether they exist as cations anions or molecular species in water. Therefore collector molecules may be ioniing compounds which dissociate into ions in water or non
