As an example, for manufacturing of AZS fused cast blocks, a batch consisting of silica (SiO 2 ), alumina (Al 2 O 3 ), zircon (ZrO 2 .SiO 2 ) or zirconia (ZrO 2 ), and soda ash (Na 2 O) and about 50% batch weight of recycled fused …

The dolomitization process results in a slight volume reduction when limestone is converted into dolomite. This can produce a porosity zone in the strata where dolomitization has occurred. ... The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel. In agriculture, dolomite is used ...

dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg(CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume.Dolomitization involves recrystallization on a large scale. The …

Processes in magnesium smelting via the Pidgeon process include dolomite calcination, grinding and pelleting, and vacuum thermal reduction. The equipment that is mainly used for dolomite calcination is …

The process of formation of dolomite is called dolomitization (Tucker and Wright, 1990). Dolomite is dominantly a marine mineral / rock but it can also be formed …

Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate and/or dolomite (calcium and magnesium carbonate), along with minerals. Lime production begins by extracting limestone from quarries and mines. Sizing . . . Limestone enters a primary crusher to break the rock.

Dolomite is an important industrial raw material for the production of metal magnesium. However, the calcination of dolomite is a typical pollution-intensive industry and is one of the major contributors to CO 2 emissions in China. The requirements of energy conservation and environmental protection are driving the development of new …

In this process, closed-end, nickel-chromium-steel alloy retorts are filled with a mixture of calcined dolomite ore and ferrosilicon, which are heated until magnesium crowns form. Each cycle takes about 11 hours, requires manually filling and emptying of the vacuum tubes, and uses about 11 tons of raw materials for every one ton of magnesium ...
