Sodium oxido(trioxo)manganese - Preparation Method
Open Data Verified Data
chlorine oxidation method: the soft manganese ore powder (or recovered manganese dioxide) crushed to 100 mesh or more is 1:0. 9~1 t 1.10 mixture with caustic soda, after heating at 400N500 ℃ oxidation roasting 8~12h, the manganese dioxide is converted into Sodium manganese, and then water or mother liquor
After leaching, chlorine is added at 93~95 ℃ until the pH value is 6.5~6.8 to prepare sodium permanganate solution, which is concentrated by evaporation, crystallized and centrifuged, sodium permanganate crystals were obtained as finished products.

Sodium oxido(trioxo)manganese - Safety
Open Data Verified Data
liquid products are generally for our own use, with the pump into the tank can be, do not need to package. Can also be used in polyethylene plastic drum or storage tank closed packaging. It belongs to class I inorganic oxidant, risk code number: GB 5.1 class 51047. UNN0.1503; IMDG CODE page 5183, Class 5.1. Liquid products are packaged in closed form in polyethylene plastic barrels or tanks. Store in a cool, ventilated, dry warehouse. Prevent sun and rain during transport. It is strictly prohibited to mix with other commodities and keep away from heat sources and fire. When loading and unloading should be light to prevent packaging damage. Operators should wear work clothes and gloves. Fire can be suppressed with water and sand. Toxicity and protection: see potassium permanganate.
