Rock Crushing methods and How to recover gold from Ores

Another possibility that needs to be considered is the use of mercury in capturing the finest gold particles from your ores. In most instances if you are just handling a few gold Quartz specimens that you find here and there, the use of mercury will not be worth your time. In some cases the gold in the ore is extremely fine sized, and using mercury to capture it makes sense. This is

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

A human skeleton dating from 5000BCE was found covered in vermillion, also known as cinnabar (HgS). Another historic example of mercury use was found in a 15 th century BCE Egyptian tomb ceremonial cup. Humans have been mining mercury ore from the deep earth (the "lithosphere") since at least the Roman times. The Romans operated a mercury

Extracting Gold

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

How mercury is made

The process for extracting mercury from its ores has not changed much since Aristotle first described it over 2,300 years ago. Cinnabar ore is crushed and heated to release the mercury as a vapor. The mercury vapor is then cooled, condensed, and collected. Almost 95% of the mercury content of cinnabar ore can be recovered using this process.
