What is Flotation Process in Mining Industry?
The flotation process refers to the general term for the ore pulp flowing through each operation during ore flotation. In the flotation operation, different types of ore should be treated with different flotation procedures. Therefore, the flotation process can reflect the process characteristics of the ore.
