DolomiteWikipedia

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 .

manufacturing process of dolomite

 · manufacturing process of dolomite offers 307 sponge iron plant products. About 30% of these are cement making machinery, 3% are crusher, and 2% are mineral separator. A wide variety of sponge iron plant options are available to you, such as free samples.

MagnesiumEssential Chemical Industry

Dolomite ore is crushed and heated in a kiln to produce a mixture of magnesium and calcium oxides, a process known as calcining: The next step is reduction of the magnesium oxide. The reducing agent is ferrosilicon (an alloy of iron and silicon) which is made by heating sand with coke and scrap iron, and typically contains about 80% silicon.

Dolomite – Its Processing and Application in Iron and

The most common process for the production of sintered dolomite is a single stage firing process in a shaft kiln or a rotary kiln. The raw dolomite is charged into the kiln and, while progressing through the kiln, it gets decomposed in two steps.
