Heap Leaching of Gold and Silver Ores - ScienceDirect

Jan 01, 2016  To those of us in the gold industry, the question “What is heap leaching?” seems to have an obvious answer. In the simplistic sense, heap leaching involves stacking of metal-bearing ore into a heap on an impermeable pad, irrigating the ore for an extended period of time (weeks, months, or years) with a chemical solution to dissolve the sought-after metals, and collecting the leachant ...

Oct 10, 2019  In ferric leaching, the gold extraction was slightly lower 85–89% (with ferric concentration of 0.1 M and 0.04 M). However, notable is that gold was able to dissolve without any initial cupric or ferric addition, with a gold extraction of as high as 87%, when the oxidant originated in-situ from the gold ore.

Gold Metallurgy and Leaching Process

Jun 24, 2015  Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes:

During the leaching of the Au-Cu sulfide ore, gold dissolution occurred concurrently with copper dissolution at 25 °C. This observation was attributed to galvanic interactions since the sulfide ore naturally contained pyrite. Increases in glycine concentration also improved the dissolution of both copper and gold from the sulfide ore.
