Mineral Resource of the Month: Fluorspar

Fluorite occurs in a variety of geological environments deposited under a wide range of chemical and physical conditions, but commercial sources are primarily hydrothermal. The most common deposits occur as veins, mantos (replacement strata-bound orebodies), or replacement deposits. Other important deposits include stockworks and fillings in shattered zones, carbonatite and alkalic rock complexes, residual concentrations resulting from the weathering of primary deposits, and recoverable gangue in base metal deposits.

Mineral Resource of the Month: Iron and Steel Slag

Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes. Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten crude iron or steel; the slag is then removed from the liquid metal.

Mineral Resource of the Month: Lime

Lime is the common term for several chemicals in three major categories: quicklime, hydrated lime and refractory dead-burned dolomite. Lime is almost never found naturally. It is primarily manufactured by burning limestone in kilns, followed by hydration when necessary.

Mineral Resource of the Month: Pumice and Pumicite

Pumice is an extrusive igneous volcanic rock formed through the rapid cooling of air-pocketed lava, which results in a low-density, high-porosity rock. Fine-grained pumice, or pumicite, is defined as minute grains, flakes, threads or shards of volcanic glass, with a size finer than 4 millimeters.
