Flotation equipment is the mechanical equipment that realizes the froth flotation process and separates the target mineral from the ore. At present, nearly 2 billion tons of ore is processed through the froth flotation process in the world. Flotation equipment is suitable for the separation of non-ferrous metals, ferrous metals, precious metals, non-metallic minerals and chemical raw materials, and the recovery of useful minerals. It is mainly used for the selection of non-ferrous metals such as copper, zinc, lead, bismuth, gold, etc. It can also be used for ferrous metals and Non-metallic rough selection and selection.
Flotation equipment includes Flotation Machine and flotation aids. Flotation machine is an important equipment to realize the flotation process. During flotation, the slurry and flotation agent are blended and sent to the flotation machine. After being stirred and inflated, the mineral to be floated is attached to the bubble to form a mineralized foam layer. The foam is scraped off with a squeegee or spilled in a self-draining manner to obtain a foam product, while the non-foam product is discharged from the bottom of the tank. Flotation technology economic indicators are closely related to the performance of the flotation machine used.
The application fields of flotation equipment are continuously expanding, from mineral separation to industrial wastewater treatment, oil field wastewater treatment, deinking of waste paper, and flotation separation of microorganisms.
Flotation equipment can be divided into four major categories according to their different aeration and stirring modes: mechanically agitated flotation machine, gas-stirred flotation machine, inflated flotation machine, flotation column, induced air flotation machine, air separation flotation machine.
The flotation machine mainly consists of slurry tank, stirring device, inflator device, exhaust mineralization bubble device, and motor. The flotation machine will grind the ore, add water and necessary chemicals into the slurry after grinding or grinding, and then inject into the slurry tank that starts stirring to introduce air into the slurry to form a large number of bubbles. Water particles that are not easily wetted by water, that is generally called hydrophobic minerals, attach to the air bubbles and float together with the air bubbles to the surface of the pulp to form mineralized bubble layers. Others are easily wetted by water, which is generally called hydrophilic. The mineral particles do not adhere to the air bubbles, but remain in the pulp, and the mineralized air bubbles containing specific minerals are discharged to achieve the purpose of beneficiation.
