As a chemical substance, manganese sulfate will appear as impurities in the production process. The manufacturer will carry out purification treatment before leaving the factory. The finished product is what we need. The removal of iron is an important process. Here is a detailed introduction to everyone.
The domestic production process of manganese sulfate is divided into rhodochrosite method, pyrolusite method and by-product method according to the raw materials for production; according to the refining process, it can be divided into high temperature roasting method, acid leaching method, two-mine adding acid method, sulfur dioxide method and other sulfuric acid. Ferrous method, manganese monoxide method, comprehensive utilization method, etc. In all production processes, acid leaching is required. During the acid leaching process, impurities such as Fe, Al, Zn, Co, Ni, and Pb are leached with manganese. In actual production, due to various factors, the experimental process conditions are often not met, and the impurity content in the leachate cannot meet the standards required by the relevant high-purity manganese sulfate industry. Therefore, the study of the purification and removal of various impurities in the leachate is of great significance to the development of the entire manganese industry.
Iron is an important companion element in manganese ore. In the process of leaching of manganese ore, iron enters the manganese sulfate solution in the form of Fe2+ and Fe3+. In order to ensure the removal of heavy metals, the iron in the solution is generally removed before removing heavy metals. ion. Hydrolysis and precipitation method has the advantages of simple process, easy control of operating conditions, high working efficiency, and adhesion of heavy metal ions to suspended colloid in solution, which is suitable for industrial production.
I believe that after reading the above introduction, we also understand the removal of iron in the manganese sulfate solution. In fact, the process is relatively simple. If you do not understand the actual operation, you should consult in time. When choosing a manufacturer, remember to choose a regular manufacturer to avoid Buying impurities to remove unclean products affects normal use.
