boom ... is this it!!!
it is possible to leach 85.1% of gold from an ore deposit. This is an extraction rate similar to that of cyanidation.

Cleaner gold extraction technology goes global

A technology that enhances the extraction process of a number of metals and that was developed by scientists at Australia’s Curtin University made it to the global market after the sale of the researchers’ industry partners Mining and Process Solutions (MPS).
Czech multinational chemical supplier Draslovka is the company behind the acquisition of MPS, whose leaching technology uses amino acids such as glycine for the extraction of gold, copper, cobalt and nickel.
The system works through a combination of potassium permanganate and glycine, which partially decompose to form insoluble manganese dioxide, insoluble calcium oxalate, and nitrogen – all of which are naturally occurring, low-toxicity chemical compounds.
With low concentrations of potassium permanganate being added to the alkaline glycine system at ambient temperature, it is possible to leach 85.1% of gold from an ore deposit. This is an extraction rate similar to that of cyanidation.
“Now that it has made it to the global market, this technology will offer many benefits to resource industries, including being a much more efficient, safe and environmentally-friendly extraction method.
By developing the glycine leaching technology, thus, the scientists have optimized the process to enable the extraction of a range of precious and base metals. |
