A PROCESS FOR PRODUCING MANGANESE SULFATE SOLUTION FROM MANGANESE ORES CONTAINING POTASSIUM IMPURITY |
摘要 |
<p>Manganese sulfate solutions of improved purity are prepared by digesting a combination of a reduced manganese ore with an aqueous acid solution in the presence of a particulate potassium-iron salt byproduct. The salt byproduct is the salt byproduct formed, in situ, by reaction of potassium impurity with ferric ion during digestion of a combination of a reduced manganese ore and an aqueous acid solution.</p> |
