There are three types of activated carbon adsorption for gold extraction, one is gold adsorption coconut shell activated carbon, the second is almond shell special gold adsorption activated carbon and the third is wood pellet activated carbon. Gold extraction activated carbon is refined by a specific process from raw materials, and has a high adsorption capacity. The appearance is black and irregular activated carbon, is non-toxic and odorless, large specific surface area, strong adsorption capacity, fast adsorption rate and low impurity content. It is mainly used for the separation and extraction of precious metals in heap leaching, magmatic extraction of gold, metallurgy and other industries.
