Question

Examples of non-metallic minerals are ______________.
A. Manganese, nickel, cobalt
B. Copper, lead, tin
C. Gold, Silver, Platinum
D. Coal, petroleum, natural gas

Answer 1

Hint: Minerals are solid substances found in nature that can be made up of a single element or a combination of elements (chemical compounds). Elements such as gold, silver, and carbon make up minerals.

Complete answer:
A. Nonmetallic minerals are a type of chemical element from which no new product can be produced when melted. Minerals that contain one or more metallic elements are known as metallic minerals. Mineral deposits are uncommon, naturally formed concentrations of metallic minerals. These deposits can be made up of a number of metallic minerals that contain valuable metals like nickel (pentlandite), copper (chalcopyrite), zinc (sphalerite), lead (galena), and gold (which can be found as a native element or as a minor constituent within other minerals) that are used in almost every aspect of our lives. To remove the useful metal from a metallic mineral, it must be broken apart and chemically extracted. Manganese is a chemical element with the atomic number 25 and the symbol Mn. It is not present in nature as a free element; instead, it is often found in minerals with iron. Manganese is a metal that is used in a variety of industrial metal alloys, including stainless steels. Manganese, nickel, and cobalt are examples of nonmetallic minerals. So option A is metallic minerals.

B. Metallic minerals contain valuable metals like nickel (pentlandite), copper (chalcopyrite), zinc (sphalerite), lead (galena), and gold (which can be found as a native element or as a minor constituent within other minerals) that are used in almost every aspect of our lives. So option B is metallic minerals.

C. Gold is found in mineral deposits and is a strong heat and electricity conductor. Chemically, precious metals are less reactive than most other elements. They have a high lustre and are normally ductile. And so Gold, Silver, Platinum are metallic minerals.

D. Energy minerals are used in the production of power, transportation fuel, home and office heating, and the manufacture of plastics. Actually, Energy minerals include coal, petroleum, natural gas, and uranium. They are usually non-metallic minerals. And so option D is correct as they are non-metallic minerals.

Examples of non-metallic minerals are Coal, Petroleum, and natural gas.

Note: Fuel minerals, such as coal and petroleum, are classified as such. Coal, petroleum, and natural gas are the three major sources of fuel minerals. Carbonaceous fuels are what they're called. Fossil fuels are derived from the earth and are produced by the decomposition of fossils.
