metal - Students | Britannica Kids | Homework Help
Some metals react less vigorously with oxygen, forming a powdery metal oxide that coats the metal’s surface. A nuer of metals, including iron and zinc , do not react to the oxygen in dry air; however, when both water and oxygen are present, as in moist air, these metals form a metal oxide through a process called corrosion .

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.
