Answer 2

Answer:

Explanation:

Types of Minerals: Depending upon their chemical composition and crystalline structure they are of two types :

• Metallic Minerals and
• Non-Metallic Minerals

Metallic minerals contain one or more metallic elements like Gold, Silver, Iron and Copper are extracted from these minerals. Found in igneous and metamorphic rocks. They are hard and lustrous

Classifications:
