eqitment use for mine gold from tailings

to deliver pressure filters for dry tailings processing

To minimize the use of water and improve the physical and chemical stability of our tailings, we have decided to adopt filtered tailings for the project. Salares Norte will be a benchmark plant for dry tailings processing," explains Francois Swanepoel, Technical Manager at Salares Norte. Get price

Artisanal and Small

Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. Get price

Biomineralisation

Recent advances in our understanding of bio-geochemical gold cycling suggest that gold lost to waste tailings could be recovered through the employment of novel low-cost bio-geochemical approaches. Specifically, it has been shown that microbiota (Cupriavidus metallidurans) mediate the formation of secondary gold grains (nuggets) at sites such as the Prophet Gold Mine in Queensland. Get price

Alternative Uses of Tailings

By utilising tailings as a material with value, as opposed to waste, customers are able to extract 'treasure from trash', reducing the need for a whole new mine site to mine those minerals. In the face of new challenges and a changing mining landscape, the collapse of tailings dams demonstrates that safety cannot be compromised and new technology must be considered. Get price

Minerals

Mine tailings are generally disposed of by artisanal and small scale gold miners in poorly constructed containment areas and this leads to environmental risk. Gold phytomining could be a possible option for tailings management at artisanal and small-scale gold mining (ASGM) locations where plants accumulate residual gold in their above ground biomass.
