Currently 85% of gold in the world is extracted by using gold cyanide process. In order to address highly toxic pollution of cyanide, industry experts and academics globally have undertaken extensive research to find gold extraction products that do not contain cyanide. The EarthGold environmentally-friendly GLR has played a revolutionary role in precious metal leaching.
The innovative products are generally designed to suit for leaching various gold & silver ores, all the GLRs are environmentally-friendly low toxic reagents, they can replace sodium cyanide fully in gold & silver leaching process and without change original leaching process as cyanide. It is safe and environmentally friendly when compared with the use of cyanide. No hazardous chemical handling requirements.
Early EarthGold GLR was developed on the basis of lime-sulphur-synthetic plus thiourea-alkali products, over the years R&D, we have developed a new series of EarthGold EG600 compounds with different particular composition to suit for leaching not only regular gold and silver ores but also various difficult-to treat gold and silver ores, like hi-sulfur, hi-arsenic, hi-iron gold ore etc. Its higher leaching rate, quicker extraction time, lower consumption and low toxic make it to be one of the most cost effective solution to replace sodium cyanide in precious metal leaching at present.
