Background

At present, industrial minerals become increasingly poor, fine and complex, and as comprehensive utilization and environmental protection requirements of metallurgy, chemical engineering and other processes are increasingly improved, flotation scientific technology becomes more important. The flotation is to make use of the hydrophobic and gas-philic (or oleophilic) property of the material itself or obtained after the treatment of the medicament to make the material gather at the water-gas or water-oil interface to achieve enrichment, separation and purification.

The proper dosage in the flotation process is an important means for ensuring the ash content of the flotation clean coal, improving the yield of the clean coal and reducing the consumption of medicaments. The flotation production dosing amount is determined by a conventional method of pre-dosing through detecting the flow and concentration of ore pulp and controlling the dosing amount by manually observing the gray level of tailings.
