Flotation reagents require the use of various drugs, such as frothers, collectors, etc. Under the automatic flotation dosing machine, this experimental reagent is added to all areas of flotation reagents at fixed times and support points to improve Mineral processing results. Today, we will explain the regulatory authorities of these 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 properties of minerals, the composition of the slurry and the performance standards of other chemicals, so as to improve the flotation agent effect. During the cyanidation process, it should also be adjusted The pH value of the ore slurry. Commonly used ones are lime, sodium carbonate, sodium hydroxide, and acid. In gold beneficiation, commonly used regulators are lime and sulfur.
(2) Activator. It can improve the use level of minerals and collectors, so that the activity of difficult minerals can be increased. The content of lead copper oxide ores is activated by sodium antimonide, and then flotation agents are used with xanthate and other collectors. .
(3) Retarder. The flotation automatic dosing machine improves the hydrophilicity of minerals, blocks the functions of minerals and collectors, and inhibits their floatability. For example, using lime to inhibit pyrite, zinc sulfate and cyanide Suppress sphalerite, tap water glass suppresses silicate gangue minerals, and use starch, gel (tannin) and other organic drugs as retarders to achieve the purpose of multi-metal separation and flotation reagents.
(4) Flocculant. It aggregates fine mineral particles into solid particles and accelerates their sedimentation rate in water; it can be used for selective flocculation, desliming and flocculation-flotation. Common flocculants include polyacrylamide and starch, etc.
(5) Dispersant. It prevents the accumulation of fine ore particles and forms a single state. Its function is exactly the same as that of flocculant, such as sodium silicate, phosphate, etc.
The automatic dosing machine for flotation not only ensures accurate raw materials, but also reduces the cost of labor and raw materials and improves production efficiency. It is favored by various mining plants.
