Electrolytic Manganese Flakes 99.9

China's electrolytic manganese metal production is mainly based on 99.7% of the products (most of the manufacturers have actually reached more than 99.8%), and only a few manufacturers produce 99.9% of the products (because the market demand for 99.9% of the products is small, but many enterprises are doing).Feasibility study reportWhen it is claimed to produce 99.9% of the main raw materials -Manganese oreforManganese oxide oreandManganese carbonate oreTwo categories, in addition to the different ways of making liquid in the previous process,electrolysisThe production process is basically the same.

Manganese carbonate oreIt is a direct use of sulfuric acid withManganese carbonateChemical reactionsPreparationManganese sulfatesolution, and then prepared through a series of processes such as neutralization, purification, filtration, etcelectrolyte, by adding additives such asSelenium dioxide,Ammonium sulfiteWait to enterelectrobathElectrolysis is performed; exploitManganese dioxideThe process of producing electrolytic manganese is different from the production process of manganese carbonate, mainly because manganese dioxide does not react with sulfuric acid under general conditions, and must be treated as divalent manganese and then reacted with sulfuric acid to prepare manganese sulfate solution, and the treatment method is generallyroastingThe method is to combine manganese dioxide withReductivenessSubstances (generally coal) are mixed together and heated in a closed manner, and the tetravalent manganese is reduced to divalent manganese at a certain temperature, and then reacted with sulfuric acid after crushing, which is called roasting method; The other method is called the two-mine method, which is usedManganese dioxide finesand pyrite occurs under the action of sulfuric acidRedox reactionsto prepareManganese sulfate. However, due to the high cost, these two methods are basically not used in the industry, among them, the roasting method is more common than the two-mine method, but it is used by many roasting production plantsRoasterIt is simple and easy to make, but the energy consumption is high and the pollution is largeReverberatory furnace, adoption is not recommended.
