Answer 2

Answer:

Ores are minerals that contain a large amount of a specific element, usually a metal. Rock, dirt, sediment, ash, and gemstones are all examples of ore and mineral deposits.

Explanation:

Mineral deposits arise when mineral-making ore is released and deposited by a medium that holds and conveys the ore. One such medium for transporting ores is magma. When magma or lava cools, the magma and ore within it condense to form microscopic minerals in the igneous rock that forms.

Mining is the process of exposing ores beneath the earth's crust so that they can be removed and processed by machines. Mining processes are determined by the availability of coal, copper ore, and water. Large excavation equipment is used in surface mines, but backhoes are also used to remove overburden, or dirt layers that cover an ore deposit.
