processing beneficiation involved

Beneficiation - Wikipedia

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 (concentrate) and a waste stream (tailings). Examples of beneficiation processes include froth flotation and gravity...
