The calcined dolomite is alkaline in nature. Uses of dolomite. Dolomite has several uses. Since very early days, it is being used as ornament stone. For some uses, dolomite is specifically valued for its MgO content and chemical composition is all important. It is being used in raw form, calcined form or in sintered form.

A dolomite manufacturer uses its calcined form during the sintering method of iron production. It helps remove the carbon dioxide. It is first crushed down to 3mm using hammer crushers before being introduced to the sinter mix. Some of the benefits of reaching out to a dolomite manufacturer for its calcined form include:

1 Introduction. Currently, the silicothermic is the main method for the extraction of magnesium from the calcined dolomite, and the reduction process mainly uses FeSi as the reducing agent to reduce MgO under vacuum conditions at 1200°C [].Although the cost of ferrosilicon as reductant is lower, the reduction temperature is higher while the reaction …
