Introduction to flotation process

The flotation process is a process in which ores, chemicals, and gas adhere to each other during the separation process. The adhesion (mixing) of the ores and chemicals can be achieved through the stirring tank, and then the air and air enter the flotation machine and have already How can minerals and medicines that are attached and mineralized to each other better adhere to each other, and then realize the process of separation as the foam rises.
