Dolomite is also used as a source of magnesium oxide for making magnesium metal and for chemical uses, such as the common laxative milkofmagnesia. Dolomitic limestone''s and dolomites are mined along with limestone and used for crushed stone and aggregates for manufacture of pavement, concrete for construction and as fill material.
Commodity chemicals that are also used in large volumes in the mining industry (, sodium cyanide and hydrogen peroxide, as well as explosives) are discussed in separate reports. The following pie charts show world consumption of mining chemicals by region and by type.
Magnesium is the lightest structural metal used today, some 30% lighter than aluminium, and is generally used in alloys. Pure magnesium burns vigorously once molten, but magnesium alloys have higher melting points and are widely used in the automotive and aircraft industries.
Energ9 y and Environmental Profile of the Mining Industry Limestone and Crushed Rock Crushed rock is one of the most accessible natural resources and a major basic raw material. It is used in construction, agriculture, and other industries using complex chemical and metallurgical processes. Despite the low value of its basic products, the
Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth''s crust. Learn more about the structure, properties, and uses of dolomite in .
Dolomite. Dolomite is a calcium magnesium carbonate mineral which has many characteristics similar to calcite. In places where access to limestone is not available or more costly, dolomites are used in its place for the basic materials from which most building stone and a significant percentage of crushed stone are produced.

Dolomite is used to describe both a mineral and a rock. The mineral is the pure form with a defined crystal structure and chemical formula, whereas dolomite rock is composed chiefly of the mineral Dolomite, but also contains impurities such as Calcite, Quartz, and feldspar.
This has made finding ways to separate the dolomite from the phosphate a research priority for the FIPR Institute. Another research focus in the beneficiation area is to streamline the flotation process and reduce the number or amount of reagents (chemicals) used to separate the sand and clay from the phosphate rock after it is mined.
Global dolomite mining market is expected to witness considerable growth over the next seven years owing to growing road construction industry in emerging economies such as Asia Pacific and Latin America. Dolomite rock known as dolostone is crushed and sized before it is used as a base material in road construction industry.

Shrock''s dolostone, however, never gained general acceptance in the geological community, largely because the word dolomite was originally used as a name for rocks rich in calciummagnesium carbonate, and that original rock usage takes precedence. It was afterward that dolomite was used .
Chemicals used in mining and processing minerals contaminate the land, water, and air, causing health problems for workers and people living near mines. Toxic chemicals used in mining include: cyanide, sulfuric acid, and solvents for separating minerals from ore; nitric acid; ammonium nitrate and fuel oil ("ANFO") used in blasting tunnels

LIMESTONE MINING Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
Magnesium processing, preparation of magnesium ore for use in various products. In its pure form, magnesium lacks sufficient strength for most structural applications. However, the addition of alloying elements improves its properties to such an extent that both cast and wrought magnesium alloys are widely used.
Mining chemicals represent a niche area of supply but at the same time their use is almost universal across the industry. In this month''s Spotlight Feature Article, from the June issue of International Mining magazine, Editor Paul Moore looks at .
