Open the CIPO recordAbstract From the Canadian patent
This invention relates to a method for preparing manganese chloride from at least one oxidized manganese compound. The oxidized manganese compound is lixiviated with any one of calcium chloride, magnesium chloride or alkaline and alkaline-earth chlorides. The reaction between the oxidized compound and the chloride produces the manganese chloride in a liquid form. The method provides a high productivity yet obviates the problems of corrosion in the equipment and the requirement of condensing gases as in known methods.
