摘　　要：研究了黄铁矿、锰矿粒度、酸矿比对锰浸出回收率的影响．高品位、细粒度的黄铁矿对锰浸出率的提高有显著作用．为提高锰的浸出率，提出了锰矿中浸、酸浸二段浸出流程．此外还探讨了黄铁矿还原氧化锰矿的反应机理．The effect of pyrite particle size of pyrolusite and sulfuric acid/pyrolusite ratioon the extraction of manganese was studied.It showed that pyrite with high content and fineparticle size significantly improved the extraction of manganese. To get high manganeseextraction from pyrolusite,a process with、neutral and acid leaching was suggested.Themechnism of pyrolusite reduction py pyrite has also been discussed

关 键 词：氧化锰矿 黄铁矿 浸出工艺 回收率
