Acid dissolution method is associated with the removal of iron by PTMS magnetic separation
magnetic separator factory
Acid dissolution method is to convert insoluble iron impurities in kaolin into soluble matter in acidic solution (hydrochloric acid, sulfuric acid, oxalic acid, etc.), so as to achieve separation from kaolin. The effect of PTMS magnetic separation on the removal of iron is related to the occurrence state of iron, the amount of acid and the reaction temperature, etc. It is effective for hematite adsorbed on the surface of kaolin in the form of immersion (soluble in acid).
PTMS magnetic separation
But it is difficult to work with other forms of iron minerals (iron sulfide, ilmenite). Pyrite is a common harmful iron impurity in non-metallic ores. It can be removed by biological oxidation PTMS magnetic separation by thiobacillus ferrooxidans. Under the action of thiobacillus ferrooxidans, the oxidation formula of pyrite.
what is magnetic separation in chemistry ?
In the process of iron removal by PTMS magnetic separation of pyrite, the appropriate initial Fe2+ concentration can not only ensure the nutrients required for the growth of thiobacillus ferrooxidans, but also promote the development of thiobacillus ferrooxidans in the absence of Fe2+. The oxidation of Fe3+ and S- in FeS2 to produce H2SO4 is the main life activity, and the oxidation rate is high and energy is obtained from it. This characteristic makes thiobacillus ferrooxidans become an important strain in the field of bacterial metallurgy.
