Sell the best dolomite for the extraction of magnesium
Dolomite is found in the form of massive layers of several decades thick. They make up about 15% of the Earth’s crust and are found in large quantities throughout the world and are known as a common component of sedimentary rocks. Dolomite containing stones are known as dolomite dolomite or limestone dolomite. Perhaps there are no other minerals, which have the use of limestone and dolomite.
Projection of magnesium ingot from dolomite ore
Magnesium metal is considered as a light metal with favorable physical and mechanical properties in today’s world. The automotive and aerospace industries, as major consumers of magnesium metal, are replacing steel and aluminum parts with lighter magnesium components to reduce vehicle power consumption. Magnesium is also used as an alloying element in the production of aluminum alloys, another part of the global demand for magnesium to the alloying industry. Magnesium is one of the raw materials in the EU’s list of raw materials and strategic metals.
Dolomite is considered as one of the mineral resources of magnesium metal and is considered commercially among various sources of this metal. The process of thermal recovery of magnesium from dolomite ore due to the possibility of using relatively clean and inexpensive natural gas is of interest to major industrialized nations, including China, which accounts for more than 85% of the world’s magnesium in China, and mainly by the revival method Siliconera.
In the process of restoring magnesium silicon metamorphic (Pidgeon Process) from dolomite ore, dolomite ore first is calcined during a baking process in a furnace at a temperature of 1200-10000 degrees Celsius. Calcified dolomite with Ferrosilicon and Fluoride (Calcium fluoride) are mixed as other raw material and briquetted to the recovery furnaces. In refrigeration furnaces, briquettes are placed in special rituals at temperatures between 1200-100 ° C and under vacuum conditions, and magnesium regeneration is performed. Magnesium is obtained in the form of vapor in special containers of condensation in the form of magnesium crystals. Magnesium crystals produced after melting and filtration in melting furnaces are produced in special molds and magnesium ingots.
