Periodically, (on the order of 1 – 2 days) the wash plant is shut-down and the gold is removed. The concentrate may then be subjected to further, more refined concentration, with gravity separation techniques such as jigs, shaking tables, gold centrifugal concentrators and pinched sluices, and possibly magnetic separation if magnetite is present, to produce a high …

Health Effects. Illegal mining can create areas of stagnant water where mosquitoes can spread illnesses such as malaria to the miners. In Brazil's Yanomami territory alone, there are about 30,000 Indigenous people and about 20,000 workers who are involved in illegal gold mining. When the workers relocate, they further spread these diseases among the Indigenous population.

After the gold ore has been removed from the earth using mining equipment, it is sent to a gold processing plant. 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.
