1. Before loading the amalgam can advance in the distillation tank wall is coated with a slurry of chalk powder, graphite powder or talc to prevent adhesion of gold powder and the tank wall. Laboratory Common consumables refers to basically Liquid-separating pipe, Disposable test tube, Screw Cap Tubes and Caps with "O" Rings, PFA volumetric flask,and High temperature and high pressure disinfection basket, high temperature and high pressure tray and Laboratory Plastic Petri Dish Sterile Dish Products.

2. The mercury paste in the tank should not be too thick. Generally, it is 40 to 50 mm. It is too thick to prolong the heating time. It is easy to cause the mercury to not be completely distilled out. It is also easy to eject the gold from the tank when the mercury is boiled.
3. The mercury paste must be pure, and the wrapping paper should not be mixed. Otherwise, when the recovered mercury is reused, it is prone to mercury pulverization. When the mercury paste is mixed with heavy minerals and a large amount of sulfur, it is easy to perforate the bottom of the tank, causing gold loss.
4. The tank should be heated slowly. If the temperature rises too fast, it will cause the mercury to boil and sneeze. When most of the mercury escapes, the temperature of the furnace can be raised to 750-800 °C, and distillation is continued for 30 minutes at this temperature. In order to completely discharge residual mercury.
5. The end of the extraction iron pipe of the tank should not be in contact with the water surface of the cooling water basin below which the condensed mercury is collected, in order to prevent an explosion accident when the negative pressure generated in the tank at the end of the distillation draws water into the tank. Keep the environment well ventilated during distillation.
