What are Advantages of Mineral Processing?
Advantages of Mineral Processing. It makes mineral resources profitable. It increases the value of the ore by removing gangue. It allows for increased mining production. It supports the extractive metallurgy industry by minimizing metallurgical losses. It's less costly (when compared to the direct purification of mineral ore).
