Some of the industrial minerals commonly used in construction, such as crushed stone, sand, gravel, and cement, are called aggregates. Industrial minerals are extremely versatile; most have at least two, sometimes many more, applications and span multiple markets. Talc, for example, is used in cosmetics, paper, and plastics.
The U.S. mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, metals such as iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks. Oil and natural gas extraction (NAICS code 211) is not included in this industry.

These articles would help you to purchase good quality raw material at right price. These will also help you to check the quality of the material and discuss common issues people face while purchasing raw material.
RAW MATERIALS. Efficient use of natural resources is critical to sustainability. The steel industry uses advanced technologies and techniques to increase production yield rates, reduce its energy requirements, and facilitate the use of by-products. On average, 20 GJ of energy is consumed per tonne of crude steel produced globally.
