Explanation:

Metallic minerals are minerals which contain one or more metallic elements. They occur in nature in a solid state and can be extracted from their ores by various methods. These minerals are the primary sources of metals like iron, copper, aluminum, zinc, nickel, gold, silver, etc.

Types of Metallic Minerals:

There are several types of metallic minerals, such as:

- Ferrous minerals: These minerals contain iron and include minerals like hematite, magnetite, limonite, and siderite.
- Non-ferrous minerals: These minerals do not contain iron and include minerals like copper, aluminum, zinc, lead, and gold.
- Precious metals: These metals are rare and valuable and include metals like gold, silver, and platinum.

Occurrence of Metallic Minerals:

Metallic minerals are found in different geological environments like igneous, sedimentary, and metamorphic rocks. Some of the common occurrences of metallic minerals are:

- Igneous rocks: Metallic minerals like copper, nickel, and platinum occur in igneous rocks like basalt and gabbro.
- Sedimentary rocks: Iron ore deposits are found in sedimentary rocks like shale, sandstone, and limestone.
- Metamorphic rocks: Metallic minerals like gold and silver occur in metamorphic rocks like quartzite and slate.

Extraction of Metals from Metallic Minerals:

Metals are extracted from metallic minerals by various methods like:

- Hydrometallurgy: This method involves the use of aqueous solutions to extract metals from their ores.
- Pyrometallurgy: This method involves the use of high temperatures to extract metals from their ores.
- Electrometallurgy: This method involves the use of electricity to extract metals from their ores.

Conclusion:

In conclusion, metallic minerals are the primary sources of metals and occur in nature in a solid state. They can be extracted from their ores by various methods like hydrometallurgy, pyrometallurgy, and electrometallurgy. They are found in different geological environments like igneous, sedimentary, and metamorphic rocks. Thus, option A is the correct answer as it contains metal in raw form.
