Purpose
Manganese sulfate, one of important trace element fertilizers, used as base fertilizer, seed soaking, seed dressing, topdressing and foliar spraying, can promote crop growth and increase yield. In animal husbandry and feed industry, it can be used as a feed additive to better breed livestock and poultry and has fattening effect. It is also the raw material for processing paint and ink drier manganese naphthenate solution. In addition, it is used as a catalyst in the synthesis of fatty acids. Further, it can also be used as raw materials for papermaking, ceramics, printing and dyeing, ore flotation, electrolytic manganese production and manufacturing of other manganese salts.
