Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral concentration processes. Such processes are designed to remove as much as possible of the waste rock, known as gangue. Flotation separation generally is …

Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth’s crust. In nature it occurs chemically combined with oxygen and other elements. In the pure state it is soft and ductile, but it can be alloyed with many other elements to increase

Nonmetallic Mining Nonmetallic mining is a widespread activity in Wisconsin. The variety of geologic environments provides for a diverse industry. An estimated 2,000 mines provide aggregate for construction, sand, gravel and crushed stone (limestone and dolomite) for road building and maintenance as well as for agricultural use as lime.
Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.
