New gold extraction method both cheaper and faster

Apr 18, 2017  New gold extraction method both cheaper and faster - Researchers have developed technology that can bring down the cost of extracting gold from oxidised copper ores. The new method uses ammonia-cyanide leaching to extract gold and is a much faster process.

It Started With An Idea New Gold Recovery

Instead of only going after gold nuggets and flakes, we examined the subject of mineral extraction at a microscopic level. With our proprietary, proven and cost effective technology we are able to extract up to 90% (or more) of the gold present in mine tailings. Developing the technology and proving it could be done was only the first step.
