Solved: 34 The process of copper production are shown below. Mining
The copper production process involves several steps. Mining extracts the raw copper ore from the earth. Crushing reduces the ore's size for easier processing. Concentration separates the copper-bearing minerals from waste rock. Smelting melts the concentrated ore to extract the copper. Refining purifies the copper to a high level of purity.

Froth Flotation Process
The ore is crushed in the copper froth flotation process in order to separate the copper minerals from the gangue minerals. After that, the resulting slurry is floated, a process in which air bubbles are added to the slurry and the copper particles cling to the bubbles, rising to the surface as froth.

Explaining the Process of Froth Flotation
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which …
