Beneficiation

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 . There are many different types of beneficiation, with each step furthering the concentration of the original ore. History. Iron beneficiation has been ...

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the lowgrade phosphate ore is, hence, of great necessity.
