Question

Explain the types of minerals , and how it gets extracted ?​

Answer 1

Your answer
The primary methods used to extract minerals from the ground are:

Underground mining
Surface (open pit) mining
Placer mining
The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Higher-grade metallic ores found in veins deep under the Earth’s surface can be profitably mined using underground methods, which tend to be more expensive. Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods. Many industrial minerals are also mined this way, as these ores are usually low in value and were deposited at or near the Earth’s surface. In a surface mine, hard rock must be drilled and blasted, although some minerals are soft enough to mine without blasting.

Placer mining is used to recover valuable minerals from sediments in present-day river channels, beach sands, or ancient stream deposits. More than half of the world’s titanium comes from placer mining of beach dunes and sands. In placer operations, the mined material is washed and sluiced to concentrate the heavier minerals.

Answer 2

Answer:

Metallic Minerals: Minerals which contain metals in raw forms are called metallic minerals. Metallic minerals are further classified into ferrous and non-ferrous minerals.

Ferrous Minerals: Minerals which contain iron are called ferrous minerals, e.g. iron ore, manganese and chromite.

Extraction process:

1. Ferrous metals have to be extracted from iron ore. ... In the case of iron, a less-reactive metal, it can be extracted by reduction with carbon or carbon monoxide. Iron is then extracted from iron ore in a huge container called a blast furnace. Oxygen must be removed from the iron oxide to leave the iron behind.

2. Metallic minerals are minerals which contain one or more metallic elements. Metallic minerals occur in rare, naturally formed concentrations known as mineral deposits. ... Metallic minerals must be broken apart and chemically processed to extract the useful metal from the mineral.
