Mineral Production by Type

Postby fwiggins » Tue Jun 07, 2011 3:25 pm

A mineral is defined as any of a class of substances occurring in nature, usually comprising inorganic substances, as quartz or feldspar, of definite chemical composition and usually of definite crystalline structure. They, however, sometimes also include rocks formed by these substances, as well as certain natural products of organic origin, such as asphalt or coal.
Types of Minerals
Gold is a soft, yellow, corrosion-resistant element. It is the most malleable and ductile metal, occurring in veins and alluvial deposits and recovered by mining or by panning or sluicing.
Silver is a lustrous, white, ductile, malleable, metallic element, occurring both uncombined and in ores, such as argentite.
Aluminium is a silvery-white, ductile, metallic element and is the most abundant in the earth's crust. It is found in combination, chiefly in bauxite.
Bauxite is the principal ore of aluminium, composed mainly of hydrous aluminium oxides and aluminium hydroxides.
Sand/Gravel is small loose grains of worn or disintegrated rock or an unconsolidated mixture of rock fragments and pebbles.
Limestone is a common sedimentary rock consisting mostly of calcium carbonate, CaCO3. It is used as a building stone and in the manufacture of lime, carbon dioxide, and cement.
Salt is a crystalline compound, sodium chloride, NaCl, which occurs as a mineral.
Clay is a fine-grained, firm, earthy material that is plastic when wet and hardens when heated. It consists primarily of hydrated silicates of aluminium and is widely used in making bricks, tiles, and pottery.
Crushed Stone is a concreted earthy or mineral matter (rock) that is quarried and worked into a specific size and shape for a particular purpose.
A diamond is an extremely hard, highly refractive crystalline form of carbon that is usually colourless and is used as a gemstone and in abrasives, cutting tools, and other applications.
Gypsum, hydrated calcium sulphate (CaSO4∙2H2O), is a very common mineral occurring in crystals and in masses. It is soft enough to be scratched by the fingernail and is used to make plaster of Paris, as an ornamental material and as a fertilizer.
Anhydrite is a colourless, white, grey, blue, or lilac mineral of anhydrous calcium sulphate (CaSO4), occurring as layers in gypsum deposits.
Marble is a metamorphic rock formed by alteration of limestone or dolomite, often irregularly coloured by impurities, and used especially in architecture and sculpture.
Silica Sand is the dioxide form of silicon, SiO2, occurring especially as quartz sand, flint, and agate. It is usually used in the form of its prepared white powder chiefly in the manufacture of glass, water glass, ceramics, and abrasives.
Stone is the hard, mineral substance of which rock consists.
Clay/Fill is a fine-grained, firm earthy material that is plastic when wet and hardens when heated. It consists primarily of hydrated silicates of aluminium and is widely used for making bricks, tiles, and pottery.
Lime sand & Silt are sedimentary materials consisting of very fine particles intermediate in size between sand and clay.
Dolomite, essentially CaMg(CO3)2, is a white or light-coloured mineral that is used in fertilizers, as a furnace refractory, and as a construction and ceramic material.
Limestone (Marble Grade) is a common sedimentary rock that consists mostly of calcium carbonate, CaCO3. It is used as a building stone and in the manufacture of lime, carbon dioxide, and cement.
Crude Oil is unrefined petroleum, which is a thick, flammable, yellow-to-black mixture of gaseous, liquid, and solid hydrocarbons that occurs naturally beneath the earth's surface.
Natural gas comprises gases, occurring in underground deposits, whether liquefied or gaseous, consisting mainly of methane.
Other refers to some other type of mineral not so far mentioned.
