Answer 2

Answer:

Explanation:

An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores or even dressing or benefaction.

Now there are numerous ways to carry out the concentration of ores. The correct method is chosen based on the physical and chemical properties of the metal. They are:

1) Magnetic separation

2) Hydraulic washing

3) Froth flotation

4) Leaching (Chemical method)
