What are the two types of minerals? a. industrial and environmental b. valuable and invaluable c. metallic and nonmetallic d. important and unimportant

Answer;

-Metallic and nonmetallic

Explanation;

-Metallic minerals are minerals which contain one or more metallic elements. Metallic minerals occur in rare, naturally formed concentrations known as mineral deposits. These deposits can consist of a variety of metallic minerals containing valuable metals such as nickel, copper, zinc, lead (galena) and gold that are used in all aspects of our daily lives.

-Nonmetallic minerals are a special group of chemical elements from which no new product can be generated if they are melted. Nonmetallic minerals are, for example, sand, gravel, limestone, clay, and marble. Such materials lack metallic characteristics like good electric and thermo conductivity, luster, rigor, and malleability; they are, however, essential for many industries.
