Metallic Mineral Mining The Process amp; the Price

2016421ensp;0183;ensp;4 Metallic Mineral Mining The Process amp; the Price Metallic mineral mining refers to the extraction of both ferrous and nonferrous metals. Sulfide mining is a term often used to describe the mining of nonferrous metals, including copper, lead, zinc, and others, because these metals frequently are bonded to sulfur, forming sulfide compounds.

Ore

2019620ensp;0183;ensp;An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The ore grade, or concentration of an ore
