Ausome: Non-Toxic Technology Extracts More Gold From Ore

Oct 13, 2021  Traditionally, once gold ore is mined from the ground, it’s crushed to a powder and passed through a series of tanks in a process called leaching. Cyanide is then used to separate the gold from the ore into the leached solution. With the new process, the leaching and recovery process is done with chloride, one of two elements in table salt.

It Started With An Idea New Gold Recovery

Present day placer mining uses pans, water and gravity, just like the prospector of 1849, only on a larger scale. This “modern” placer technology only recovers up to 40% of the gold from every ton of ore concentrate (finely ground ore) as it primarily targets nuggets and flakes of gold. The remaining 60% goes untouched.
