The process reduces the number of dolomite calcination steps, which could save a large amount of energy. Furthermore, the use ratio of the dolomite-talc ore is high compared with that of the traditional carbonization technique. 5. Conclusions. The dolomite-talc powder was dissolved using hydrochloric acid to obtain the solution of …
The magnesium ions replace the calcium ions in the calcite, resulting in the formation of dolomite. This process is known as dolomitization and can occur in both marine and non-marine environments. Dolomite is often found in thick units of great areal extent in many sequences of chiefly marine strata. It is also commonly found in …
The sintering process requires dolomite due to its high silica (SiO2) content. Every paint industry mineral supplier suggests the same, as SiO2 counters the effect of alumina (Al2O3) in the furnace.
