Question

what are minerals ?Explain the methods of extraction of minerals.​

Answer 1

Answer:

In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure, that occurs naturally in pure form.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.

A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.

• Underground mining.

• Surface (open pit) mining.

• Placer mining.
