Amalgamation gold extraction is an ancient method. As far back as China's Spring and Autumn Period (770 BC - 476 BC), our people have already known that gold can form amalgam with mercury (commonly known as mercury paste). Because of its low cost, high efficiency, simple installation and convenient operation, the amalgamation method has been widely used. The amalgamation method in modern gold production still plays an important role, mainly for recovering the natural gold in the ore which is in a free state or has been dissociated by the monomer.

The mercury amalgamation method can be divided into two types, namely, internal mixed mercury and externally mixed mercury. Internally mixed mercury refers to a method of mixing mercury and extracting gold while grinding the ore in the grinding equipment . An outer gold amalgamation commonly used in the beneficiation plant vein free gold recovery section advance beneficiation process. Internal amalgamation is commonly used to treat higher grade ore or re-concentration concentrates.

At present, major gold producing countries such as South Africa and the United States are constantly developing new and efficient amalgamation equipment. China's mineral processing workers have also done a lot of work in this respect, and have achieved many achievements in strengthening the amalgamation operation, strengthening the amalgamation operation, and improving and developing the mercury amalgamation equipment. Mercury is harmful to humans and must be protected during operation. As long as the operating conditions are strictly controlled, mercury contamination can be minimized.
