  • Liquation - Wikipedia

    Liquation is a metallurgical method for separating metals from an ore or alloy. The material must be heated until one of the metals starts to melt and drain away from the other and can be collected. This method was largely used to remove lead containing silver from copper, The ratio of lead to copper in these cakes is an important factor for the
