The typical gold processing plant begins with a cone crusher, to reduce the particle size of the ore. Next, it is loaded on a conveyor belt, where an overbelt magnet removes tramp metal from the gold mining process. The ore goes for preliminary screening, followed by stream sampling, which is a process that uses a hammer sampler. A semi ...

The initial step in the gold refinery process involves the extraction of gold ore from the ground. This is done through mining methods that depend on the location, accessibility, and quality of the ore deposit. Underground mining techniques, such as tunneling and shaft mining, are employed to extract gold ore from deep within the Earth.
