Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
It has the ability to collect unliberated gold that remains trapped/attached to rock as well as the super fine gold particulate that escapes when mercury amalgam is squeezed and condensed Field experiments conducted in 2009 showed that the mercury method recovers about 88% of gold whereas direct smelting yielded recoveries of 95%
