What Is the Difference between Gold Flotation and Cyanidation?

Sep 06, 2019· 4.Agents. Flotation and cyanidation are both chemical processing methods, therefore, the process of mineral processing is naturally indispensable agents. Gold flotation needs ing 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.
