Fig 1 Uses and form of dolomite in iron and steel industry. Processing of dolomite. Dolomite after its mining has to undergo several processing before it can be used in various processes. The basic processes in the production of dolomite are (i) quarrying of raw dolomite, (ii) preparing mined dolomite for its use by crushing and sizing, (iii
By contrast, dolomite may dissolve much Fe (such a dolomite would not be used in glass industry), but hardly any excess Ca. Thus, a natural glass-grade dolomite always contains at least two kinds of phase, i.e. Mg-saturated limestone and Ca-saturated dolomite.
Dolomite in iron and steel industry is normally used in three forms. These are (i) raw dolomite which is also the natural form of dolomite, (ii) calcined dolomite, and (iii) sintered dolomite. When dolomite is used as a fluxing material then it is used as either raw dolomite or calcined dolomite.
2018-10-10 Dolomite is also used in paints, wall putty, ceramics, plastic industry, glass industry and fillers in detergents. Its use improves properties such as weathering action, reduces shrinkage, fissure development and water absorption. Dolomite powder can also be used as admixture, admixtures are chemicals which are added to
