peridotite is a dense, coarse-grained igneous rock consisting mostly of the minerals olivine and pyroxene.peridotite is ultramafic, as the rock contains less than 45% silica.it is high in magnesium mg 2 , reflecting the high proportions of magnesium-rich olivine, with appreciable iron.peridotite is derived from the earth's mantle, either as solid blocks and fragments, or as crystals .
blackwater is a form of pollution produced in coal preparation. in its purification, coal is crushed in a coal preparation plant and then separated and transported as a coal slurry, from the slurry, incombustible materials are removed and the coal can be sized.after the recovery of the coal particles from this slurry, the remaining water is black, contains very fine particles of coal.
basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. it is similar to fiberglass , having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber.
the little switzerland business association says the mckinney mine was the largest feldspar mine in the world, and north carolina was the largest producer. feldspar had been discarded in the process of mining mica until william dibbell sent a seven trust quality product to the ohio company golding and sons around 1910.
basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine.it is similar to fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber.it is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to .
calcium bentonite may be converted to sodium bentonite termed sodium beneficiation or sodium activation to exhibit many of sodium bentonite's properties by an ion exchange process. in common usage, this means adding 5–10% of a soluble sodium salt such as sodium carbonate to wet bentonite, mixing well, and allowing time for the ion exchange to take place and water to remove the exchanged .

employment. the european metals and minerals mining sector employs more than 200.000 people directly in the extraction and beneficiation processes and numerous jobs are depending on it, the turnover of europe alone is €13 billion euros. in addition, there are another 100.000 people working at subsidiaries across the world, depending on europe based headquarters of mining companies.
the mineral industry of russia is one of the world's leading minerammmdustries and accounts for a large percentage of the commonwealth of independent states' production of a range of mineral products, including metals, industrial minerals, and mineral fuels.in 2005, russia ranked among the leading world producers or was a significant producer of a vast range of mineral commodities, including .
process. the process of waste paper recycling most often involves mixing used/old paper with water and chemicals to break it down. it is then chopped up and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called pulp, or slurry.
