metallurgical application of dolomite

Appliion. Burnt dolomite is mainly used as metallurgical aggregate in steel production and serves primarily as MgO carrier. By adjusting a favourable equilibrium between the MgObased refractory linings and the slag the refractory wear can be drastically reduced. The CaO content is useful in almost every case with

Some studies have reported the use of dolomite as a foaming agent for the production of aluminum foam, employing powder metallurgy and melt processing. However, the foams obtained from these studies have shown common characteristics: small pore size, heterogeneous cell structure, and medium porosity levels.

The 1951 Revenue Act created a host of difficulties, including appliion of the "end use criterion" and determination of the commonly accepted meaning of such terms as limestone, dolomite, chemical and metallurgicalgrade limestone, marble, calcium car bonates, and magnesium carbonates. Dolomite, for example
