Although not as aggressive a
Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained.
Leaching Mining and mineral processing engineers who handle aqueous solutions, dissolving agents, and corrosive and erosive slurries find ANSIMAG seallessic drive pumps to be a safe and cost effective way to manage harsh chemicals and acids found in solvent extraction.

Process Introduction Heap leaching HL is a flexible and economic mineral processing method, commonly used to extract gold from low grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold containing solution is leached.
IN MINING MINERAL PROCESSING CIL CIP CIL is the simultaneous process of leaching and adsorption. This process was specifically developed for the processing of gold ores containing preg robbing materials i.e. organic carbon. These materials reduce the gold yield by attracting the gold meant for the activated carbon.
