Gold Refining

Professional recyclers recover gold from electronic waste through a controlled chain of collection, dismantling, mechanical separation, metallurgical concentration, leaching, purification, and refining. The valuable gold is usually present as thin plating or tiny components, so profitability depends on feed quality, scale, recovery efficiency, and environmental controls. This guide maps the industrial process, compares pyrometallurgical and hydrometallurgical routes, explains why informal acid extraction is dangerous, and shows how responsible recycling can conserve resources without shifting toxic risks to workers or communities.
