Refractory Gold | Mining | SGS

Gold in sulfide minerals could be liberated by oxidization using techniques such as roasting, high temperature pressure leaching or bacterial leaching. Also, grinding the ore to an extremely fine particle size can liberate gold encapulsated in sulfides.

Improved recovery of a low-grade refractory gold ore using .

In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.

However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.
