Flotation machine for copper ore dressing. Performance advantages of copper ore flotation machine. The copper flotation machine increases the collision probability of coarse particles and s, improves the mineralization effect of coarse particles, reduces the mismatch of materials and improves the recovery rate of concentrate.

Flotation is considered to be the most widely used method for beneficiation. The hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth. The froth is removed from the cell, producing a concentrate of the target mineral. The minerals that do not float into the froth are referred to as the flotation tailings ...

Introduction: The flotation machine is important for realizing the flotation process. It can process metal or non-metal minerals, such as copper, lead-zinc, lithium, antimony, fluorite, talc, etc. After the minerals undergo wet grinding, the minerals dissociated into monomers are adjusted into a slurry of a certain concentration.
