Mineral Processing Analysis in Artisanal Gold Mining, Peru

This paper analyse the mineral processing of a case study in Peru (San Cristobal) with the aim to improve the gold recovery process and mitigate the environmental impact. The process of amalgamation (gold-mercury) has been found as ineffective due to the presence of arsenic, while the particle size is not optimal to recover the gold.

The Mining Process - Newmont Corporation - About Us

Alternative Ore Processing. We use alternative gold recovery methods in some processing plants to accommodate different ore characteristics or other requirements. For example, ore that has a high level of sulfide minerals or carbon (or both) is called refractory ore. Refractory ore resists normal processing methods as the high sulfide minerals ...
