Dolomite (/ ˈ d ɒ l. ə ˌ m aɪ t, ˈ d oʊ. l ə-/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone
Dolomite Chemical Composition A typical analysis includes: * 39% Magnesium carbonate (equivalent to 11.5% Magnesium) * 59% Calcium carbonate (equivalent to 24% Calcium) The variation in Magnesium content is low, usually +0.5 or -0.5 percentage units Mg. i.e. ranging from 11.0% to 12.0% Mg.

Manganese silicon manufacturing is more energy intensive than the ferro manganese due to the energy requirements for the reduction of the silica to silicon metal. The world's largest producers are China-which is far above all others, representing more than 50% of the world's production -India, Ukraine, Norway and Kazakhstan.
Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.

The aim of this study was to analyze the catalytic performance of natural dolomitic rock as an environmentally friendly catalyst in the reaction of Jatropha Curcas oil with methanol under microwave-assisted transesterification. The dolomite was utilized as a source of calcium oxide (CaO) and magnesium oxide (MgO).
Manganese processing plant. Manganese is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its iron making component, has accounted for most manganese demand, presently in the range of 85% to 90% of the total demand.
