Beneficiation
In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product ( ore concentrate) and a waste stream ( tailings ) There are many different types of beneficiation, with each step furthering theThe advantage is that the gold extraction process is simple, costs less, and can reduce the loss of gold in tailings The disadvantage is that because mercury is highly toxic, it has serious environmental pollution and is very harmful to human health But there is no way to solve this problem 2Chlorination methodSix kinds of beneficiation methods Prominer (Shanghai) Mining
