Properties of Commercially Important Minerals

Chapter 1: Properties of Commercially Important Minerals

Minerals are natural substances that are formed from other natural compounds undergoing various geological processes. Minerals may occur as simple salts, silicates, and pure elements. The study of minerals is termed Mineralogy.

This handbook discusses the important properties of various commercially important minerals and also describes the classification of minerals.

Classification of Minerals

The classification of minerals has undergone many changes. Minerals can be classified based on the uses, structure, and physical properties.

Classification Based on Uses

The first attempts at classification were by Theophrastos in 372-287 B.C. and Plinius in 77 A.D. They tried to classify known minerals according to their usage.

Classification Based on Physical Structure

JD Dana began the process of scientific classification in 1837. This classification was further polished and presented by ES Dana in the book System of Mineralogy in 1892 and by PV Groth.

The new Dana Classification is based on the physical properties of the minerals. This classification encompasses more minerals than the old Dana classification.

Table 1-1 compares the old and new Dana classifications:
