AMALGAMATION IN MZ Whole ore amalgamation is used for primary gold. The ratio of 4-15:1 Hg:Au is estimated in whole ore amalgamation. In some countries you can find ratios of 50:1 Indonesia The process of amalgamation itself frees up to 60 of mercury into the atmosphere. For fine grain alluvial gold the Hg is added after pre concentration
Amalgamation is a concentrating process in which metallic gold or silver or an alloy of the two is mixed with mercury either in a amalgamation drum or on a amalgamation table where the precious metal bonds with the mercury to form the metal laden mercury AMALGAM and the waste barren ore pulp are caused to travel different paths to effect.

The amalgamation method can be divided into internal amalgamation and external amalgamation according to its production method. Different mines have different methods of separating gold and heavy sand minerals. Internal amalgamation is mainly carried out in amalgamation cylinders or mills which can well control mercury pollution.
The mercury amalgamation gold extraction process has a particularly large enrichment ratio. It can obtain gold amalgam with about 30 grade from raw ore containing 2-3 gton of gold and the gold amalgam can be refined into gold with more than 70 grade in the mine which greatly reduces the transportation of semi-finished products in mines. ...
The principle of gold extraction by using mercury amalgamation method is mainly that after the mercury is added to the slurry the surface of the gold particles is wetted by mercury and then the mercury diffuses into the interior of the gold particles causing a chemical reaction.

When the gold has solidified the molten silver chloride collected on the surface is run off carrying with it a small proportion of gold. When silver is the chief impurity in the gold as in that found in Australia the process is specially applicable. The gold has a degree of purity of 99.1 to 99.7 per cent.
When the ore is treated with gold-containing polymetallic sulphides metal sulfides often adhere to the mercury plate which deteriorates the phenomenon of amalgamation. To eliminate this phenomenon the amount of lime is often used in production and sometimes the pH must be 12 or more.
