Product Introduction of Small mercury amalgam distill retort, gold refining machine with good performance

Mercury steamer know as amalgam retort. It is commonly used on amalgam distillation equipment for small and medium sized mines to select gold. It has the features of small volume, portable appearance, simple operation, high efficiency and compact design. The special water cooling device to ensure the mercury is completely liquefied.

Operation method of Small mercury amalgam distill retort, gold refining machine with good performance

1. Put the amalgam mercury mix with gold into the sealed cast iron tins. There is a condenser tube connected with the top of the iron can.
2. Heat the steel can on the Coke, gas or electric furnace
3. When the temperature reached 356°C, the amalgam will gasification, the mercury gas will run out through the iron tube 
4. The gas mercury will become Spherical droplets after go through the condenser tube, and then you can recycle the mercury.
5. In order to separate the mercury completely, gold mining plant usually maintained the temperature on 400-450°C. And in the last 30 minutes, raised the temperature to 750-800°C.
6. Distill the mercury for around 5-6hours, the gold recovery rate can reach 99%.

Main features of Small mercury amalgam distill retort, gold refining machine with good performance

1. low price, fast pay back
2. small, very easy to carry and remove
3. high efficient, easy operation
4. Hg recycle use

Working principle of Small mercury amalgam distill retort, gold refining machine with good performance

Due to mercury gasification temperature is below the melting point and boiling point of gold. We commonly used the method of distillation to separate the gold from amalgam mercury.
