Gold Recovery 101 From Sepro's Gold Recovery Experts

Gold by nature is very dense ( denser than water and denser than quartz) and malleable, causing it to grind slowly. These properties cause gold particles to preferentially report to the cyclone underflow and accumulate in the grinding circuit over time. In order to take advantage of gold's preferential deportment to the cyclone underflow, the installation of a gravity concentrator ...
