Chapter 21: Problem 31

List the common ores of magnesium and calcium.

Short Answer

Expert verified
Common ores of Magnesium are: Magnesite, Dolomite, Brucite, Carnallite, Talc, and Olivine. Common ores of Calcium are: Calcite, Gypsum, Anhydrite, and Fluorite.

Step by step solution

01

Identify Magnesium Ores

Magnesium primarily occurs in minerals such as magnesite (magnesium carbonate) and dolomite (a type of limestone which is composed of calcium and magnesium carbonate). It can also be found in other minerals like brucite, carnallite, talc, and olivine.
02

Identify Calcium Ores

Calcium primarily occurs in the minerals such as calcite and gypsum. Calcite (calcium carbonate) is one of the most common minerals, and it is the main component of sedimentary rocks such as limestone and marble. Gypsum (calcium sulfate dihydrate) is used to make Plaster of Paris. Calcium can also be found in other minerals such as anhydrite and fluorite.
