Froth floatation process is based on:
A) Specific gravity of the ore particles
B) Magnetic properties of the ore particles
C) Wetting properties of the ore particles
D) Electric properties of the ore particles

Hint: We know that in chemistry, periodic tables play a vital role. In the periodic table there are totally \[118\] elements. In the periodic table there are totally \[18\] columns and \[7\] rows. The columns are called groups. Hence, \[18\] groups in the periodic table. The rows are called periods. Hence, totally \[7\] period in the table. Each and every element having a specific symbol in the periodic table. Each element having a specific position in the periodic table, that position is dependent on the physical and chemical properties of the element.

Complete answer:
We have to remember that the froth floatation process is based on the principle of the wetting properties of the ore particles. Froth floatation process is nothing but the purification of metallic sulphide ore in the wet form. This wet of the metallic sulphide ore is due to the oil and gangue of water.
According to the above discussion, we conclude the froth floatation process is based on the principle of the wetting properties of the ore particles.

Hence, the option C is the correct answer.

Note:
We must have to know that the substance is made up of more than one metal known as alloy. Alloy is mainly made to attain both properties of combined metals. Alloys are used to enhance the hardness of the metal, enhance the tensile strength of metal and modify the colour of metals. In the world there are a lot of elements in various forms. For study and developing purposes, classification happens. Periodic table used to study the elements in easy form. If one new element is discovered, it means, based on the physical and chemical property we placed in the periodic table.
