Metallic mining projects typically generate large volumes of waste, including tailings and waste rock during the mining, milling and concentrating processes. Tailings are fine-grained rock particles that have been crushed (finely ground) to separate the desirable minerals from the ore.
Nov 18, 2015 4 Metallic Mineral Mining: The Process & 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.
