New Technology of Ferrous Sulfate Preparation

The traditional preparation of ferrous sulphate is generally made from the waste produced in the production process of titanium dioxide. The effective content of prepared ferrous sulphate can not meet the needs of modern production, and it is difficult to remove the heavy metal impurities, The use of ferrous products. Now ferrous sulphate is widely used by people more and more attention, and now we are prepared for the ferrous sulfate solution is mostly taken to dissolve the solid ferrous sulfate prepared from the deployment. But today we want to introduce to you by experiment another ferrous sulfate preparation of new technology.
Iron and steel plant production of steel products in the process will produce a lot of sulfuric acid slag waste, if not effective treatment will also harm the environment to a certain degree of pollution. We found that sulfuric acid residue through the experiment can be obtained ferrous sulfate solution, and the quality of ferrous sulfate products than the existing market is much better. The following by our ferrous sulfate manufacturers technical staff for everyone to briefly introduce its preparation method. This process is divided into two stages: 1, acid leaching stage: Weigh the grated dry sulfuric acid residue, a certain temperature, stirring conditions, according to solid-liquid ratio of 1: 3, so that Slag of iron oxides and CaO, CaS, MgO, Al2O3 is fully soluble in dilute sulfuric acid. Leaching to continue to be mechanical stirring, and strive to obtain the maximum leaching rate of Fe, in order to increase ferrous sulfate production. 2, reduction, impurity phase: acid leaching solution contains a large number of impurity ions, such as Al3 +, Mg2 +, Fe3 +, etc., with the original iron powder reduction, add CaO impurity.
Through the above new process we can get high-quality standard ferrous sulfate solution, the application effect and value and we have seen ferrous sulfate fairly even better. The use of new technology for the preparation of ferrous sulfate products, we not only get high-quality ferrous sulfate products, but also eliminates the environmental pollution caused by waste problems, the real realization of ferrous sulfate production of sustainable development.
