The automatic flotation dosing machine requires the use of various reagents, such as frothers, flotation agents, etc. Under the automatic flotation dosing machine, these reagents are introduced into any aspect of flotation at limited times and fixed points to improve Mineral processing results. Today, we will explain the regulatory authorities of some key biopharmaceutical companies. Regulatory authorities can be divided into 5 types:
(1), pH regulator. It is used to adjust the pH value of the slurry, control the surface characteristics of minerals, the composition of the slurry and the efficacy of other chemical agents to improve the flotation effect. During the cyanidation process, the pH value of the slurry should also be adjusted. pH value. Common ones include lime, sodium carbonate, sodium hydroxide, and acid. In gold beneficiation, commonly used adjusters are lime and sulfur.
(2) Activator of flotation automatic dosing machine. It can enhance the application ability of minerals and flotation agents, so that difficult-to-select minerals are activated and floated. The gold-lead copper oxide ore is activated by sodium antimonide, and then xanthate and Other flotation agents for flotation.
(3) Inhibitors. Improve the hydrophilicity of minerals, block the function of minerals and flotation agents, and inhibit their floatability. For example, use lime to inhibit pyrite, use zinc sulfate and cyanide to inhibit sphalerite, and use water glass to inhibit sphalerite. To inhibit silicate gangue minerals, starch, gel (tannin) and other organic chemical agents are used as inhibitors to achieve the purpose of multi-metal separation and flotation.
(4) Flocculant. It aggregates small mineral particles into large particles and accelerates their sedimentation rate in water; selective flocculation is used for flocculation-desliming and flocculation-flotation. Common flocculants include polyacrylamide and starch, etc. .
(5) Dispersant. It prevents the aggregation of fine ore particles and is in a monomer state. Its effect is exactly opposite to that of flocculant, such as sodium silicate, phosphate, etc.
In addition to accurate batching of fully automatic batching, automatic dosing machines for flotation can also reduce manual batching costs and improve work efficiency, and are highly favored by various mineral processing plants.
