Mercury-free gold mining technologies: possibilities

Small-scale mining usually involves the extraction of secondary gold from placer deposits (alluvial, colluvial or elluvial), which can be liberated and treated using gravity methods. In the Guianas, the most popular form of small-scale gold mining is referred to as “land dredging”, a combination of hydraulicking and suction dredging.

Artisan And Small-Scale Gold Mining Without Mercury

Our vision is to enable small-scale gold miners to achieve the same gold recovery rates as large-scale miners but with a lower cost, scalable, mobile processing plant. Small-scale miners can find it difficult to operate profitably. In Australia alone, 85% of gold tenements are inactive. This trend can be reversed and they can now better afford ...
