Gold Ore Tank Leaching vs. vat leaching
Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

Cyanide to glycine: Technology reducing use of cyanide in mining
Jackson Briggs: It is called the glycine leaching technology (GLT) and it was inspired by nature. Over a decade ago, there was some researchers at Curtin University in Perth, Australia, who observed that plants were absorbing gold and other metals out of the soil. They found that it was happening because of the presence of glycine.

Gold CIL & CIP Gold Leaching Process Explained CCD
Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.
