Our cost effective and cyanide free gold recovery process Going for Gold is being demonstrated in partnership with industry. The solution provides a safe, environmentally friendly alternative to conventional processes and could help turn many of Australia's stranded gold deposits into production.
Today's miners are a different breed, in many cases seeking only to extract gold from tailings left over from mining other minerals. But one of their tools, used for more than a century, is particularly hazardous cyanide, which separates gold from ore. Mining operations often store cyanide laced sludge in
Gold mining is one of the world's dirtiest industries; Human obsession with gold is a curse on the environment. There was a curious after effect to the 2008 global financial crisis deforestation. As the stock markets started to crash, unleashing a new wave of uncertainty across the world, people started looking for other kinds of assets that offered them a sense of certainty and stability.
The conditions outlined by the authors for optimum gold dissolution and minimum cyanide consumption are The pulp must be well aerated, the cyanide solution should be saturated with calcium sulphate, it should have at all times a minimum alkalinity of 1.0 lb. of CaO per ton, and the cyanide strength should not be more than 0.35 lb. NaCN per ton.
Complication of mining by folds and faults in the crust. 4. Low gold content in the ore. 5. Problem of removal of underground water. 6. Lack of adequate supply of fresh water on the surface in mining areas. 7. Accidents resulting from collapsing of mine roofs. Diamond Mining in S. Africa Diamond is the hardest known substance.
Mining Cyanide Destruction The destruction of cyanide in gold tailings is a crucial part of metallurgical recovery of gold. Many jurisdictions have strict regulations controlling the destruction of cyanide and metal cyanide in tailings prior to discharge into the environment.
