Feb 01, 2018Two step floatation and part of middling combined to the floatation tailing for gold leaching process resulted in high gold grade (g.t 1) and gold recovery (%) for this refractory gold ore. This process opens the possibilities of maximizing Au grade and recoveries in a muti Au carrier and low grade refractory gold ore where low recoveries are common.
Proceedings EcoIst'04 2004 [PDF Document]
Recovery and grade of chalcopyrite flotation increases substantially. At a recovery of copper 85 %, zinc recovery decreases from 42 % to 27 %. At the same time mercury recovery drops from 33 % to 24 % (Figure 4). These up to 30 % decreases of the presence of minor elements in a final concentrate were evaluated very highly.

Final Gold Recovery
Gold recovery systems also trap the other heavy elements like iron sand. Here follows some helpful information about how to accomplish the final separation.
Historically, mercury was used extensively in placer gold mining in order to form mercury gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small scale gold mining (ASGM), often clandestine, gold prospecting.
