Chemistry - Metallurgy Question with Solution | TestHub

The Pidgeon process is a thermal reduction method used for the extraction of magnesium. In this process, calcined dolomite (CaO⋅MgO) is heated with ferrosilicon under high temperature and reduced pressure (vacuum). Ferrosilicon acts as the reducing agent, and magnesium vapor is produced, which is then condensed. Hence, option (B) is correct.

$$2MgO+Si\to 2Mg+Si{O}_2$$
