Background
Mineral separation is the most important link in the production of whole mineral products and is a key department in a mineral enterprise. Generally, large-scale mining enterprises are resource enterprises for comprehensive mining, selecting and smelting. The process of physically or chemically separating useful minerals from unwanted minerals (usually called gangue) or unwanted minerals in a mineral feedstock, or separating a plurality of useful minerals, is called beneficiation.
The flotation method, which is an important beneficiation method, is a method of sorting minerals according to differences in floatability among the minerals depending on differences in physicochemical properties of the surfaces of the mineral particles, and sorting is performed by utilizing differences in wettability (hydrophobicity or hydrophilicity) of the surfaces of various mineral raw material particles to water. Generally referred to as froth flotation. Natural hydrophobic minerals are few, and a collecting agent is usually added into ore pulp to enhance the hydrophobicity of the minerals to be floated; various regulators are added to improve the selectivity; adding foaming agent and aerating to generate bubbles, attaching hydrophobic mineral particles to the bubbles, floating and separating.
The most basic behavior in the flotation process is mineralization of the flotation bubbles, i.e. attachment of minerals, drugs and bubbles. The main function of the flotation machine is to fill or suck air into ore pulp to form a large amount of fine and uniform bubbles, and the flotation process of attaching ore, medicine and bubbles is completed.
