mercury gold amalgam temperature retort

GLOSSARY OF TERMS USED IN MINING

The retort heats the amalgam to a temperature high enough to vaporize the mercury. Mercury's boiling point is about 675 degrees F, while gold's boiling point is about 4,720 degrees F. Often a retort has a water-jacketed cooling tube to recover the mercury vapor as liquid mercury for further use. Get price
