Magnesium Essential 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.
