Froth Flotation and Gold Extraction - Manhattan Gold Silver

23/07/2014  Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).

What Is the Difference between Gold Flotation and Cyanidation?

Flotation and cyanidation are both chemical processing methods, therefore, the process of mineral processing is naturally indispensable agents. Gold flotation needs foaming agent, inhibitor, activator, collector and so on. But for the cyanidation process, agent is relatively simple and the ore is just leached with cyanidation agent.
