摘要
介绍了用硫酸浸取处理黑钨碱解渣，再氧化除杂，碳酸氢铵沉淀制取工业碳酸锰，并回收渣中黑钨矿的方法。
A technique is reported in this paper that extraction of manganese carbonatesand recovery of wolframite from residues of alkoline hydrolysis of wolframite by means ofleaching the residues with sulfuric acid,oxidizing the solution for elemination of impuritiesand setting it with ammonium hydrogen carbonates.
