Leaching & Adsorption Resource Book

After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral

Gold Smelting Process Sciencing

Apr 24, 2017 · Gold is purified by means of a smelting process, which utilizes pressure, high heat and chemicals to accomplish the task. Like any metal that appears naturally in the earth, there are impurities that must be removed. Removing minerals and other impurities allows gold to be used in its purest form, which is necessary

Bioleaching Introduction, Methods, Application, Copper

Generally heap leaching process is employed in copper leaching process but sometimes a combination of heap leaching and in situ leaching processes are used. The solution (Sulphate/Fe 3 solution) is sprinkled over the heap which percolates through the ore and collects at the bottom pit. The solution collecting in the bottom pit will include copper metal, which is removed by precipitation.
