Dolomite (mineral) Wikipedia

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smeltingof iron and steel. Large quantities of processed dolo

Dolomite Its Processing and Application in Iron and

28/06/2017· The first process takes place at dolomite mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore. In the iron and steel plant, in some of the places, raw dolomite is further processed. Example is sinter plant where the raw dolomite is crushed in hammer mills to 3 mm size (generally in the range of 85 % to 90 %).

3.1. Characterization of dolomite ore The chemical analysis of New-Valley dolomite ore is given in Table 1. It is clear that, the theoretical MgO content in pure dolomite mineral is 21.875%, this indicates that, the purity of dolomite ore is about 75.66%. The ore contains a high amount of calcium oxide which causes the problems after solid/liquid

Preparation of high purity magnesium oxide from dolomite

the dolomite ore in aqueous hydrochloric acid solution was investigated with respect to the effects of time on dissolution of the dolomite sample. The dependence of the observed dissolution rate on pH was established. In the carbonation experiments changes in pH, Ca. 2+ and Mg. 2+ concentrations versus time in the effluent solution were determined. Effects of the temperature on the
