artisanal ore dressing gold mineral processing technology

  • Introducing clean and efficient mercury free gold

    Many artisanal miners use mercury to separate gold from the ore, exposing themselves, their communities, and the local ecosystems to the negative health and environmental impacts of mercury. A lack of access to education, land title, resources, finance, training, and alternative clean and efficient mineral processing technologies hinders miners from switching to alternative, mercury-free gold processing

  • Artisanal mining Wikipedia

    Gold ore is processed informally using simple technologies. Ore is first crushed by hand on open rock surface and hammerstones. This work is often done by women and children. The pulverised ore is concentrated using visual sorting, sieving, gold panning, and by washing on riffle tables made of plastic sheets on heaps of sand.
