Technical Field

Background

Manganese sulfate is used as basic manganese salt, is an important intermediate product for producing electrolytic manganese metal, other manganese salts and manganese oxides, and is widely applied to industries such as energy, medicine, fertilizer, feed, food, paper making, catalysts and the like. Particularly, in recent years, along with the rapid development of electronic chemicals in China, such as electrolytic manganese, chemical manganese dioxide, trimanganese tetroxide, lithium nickel cobalt manganese oxide ternary positive electrode materials, lithium manganate positive electrode materials and other series of high-quality and high-purity electronic chemicals, manganese sulfate is more and more valued as a main raw material for producing the electronic chemicals. But also puts higher requirements on the quality of the manganese sulfate, particularly the requirement on the content of impurities in the manganese sulfate is quite strict, and the content of heavy metal impurities in the manganese sulfate is required to reach trace level. At present, manganese sulfate in China is mainly prepared by leaching manganese ore with sulfuric acid and then removing impurities and purifying, wherein the impurity removing process mainly comprises the step of removing impurities such as iron, a part of heavy metals, calcium, magnesium and the like. In the manganese sulfate monohydrate products in the market, the content of impurities such as potassium, sodium, calcium, magnesium and the like is generally about 3000 micrograms/gram, and the content of heavy metal impurities (such as copper, nickel, zinc, cobalt and the like) is not lower than 100 micrograms/gram. In order to develop a wider market and meet the requirement of high-end electronic chemicals on the quality of manganese sulfate, manganese sulfate must be further purified to produce a high-purity manganese sulfate product with the impurity contents of potassium, sodium, calcium, magnesium, heavy metals and the like meeting the market quality requirement, so that higher requirements on the process and equipment are provided.
