摘　　要：研究了几种无机和有机添加剂对电解金属锰矿石(主要是菱锰矿)中锰的浸出率的影响.实验结果表明,葡萄糖、蔗糖等有机添加剂在常规时间里,可使锰的浸出率达到85%以上,是实际工业生产中可取的添加剂;浓硫酸虽也可提高浸出率,但由于具有强腐蚀性而不宜采用.Some organic and inorganic addition agents were tested in order to improve lixiviate rate of Manganese in rhodochrosite.The result showed that there was clear improvement of lixiviate rate of Manganese in normal hours when using organic addition agents such as glucose,sucrose,and so on,with the reaching more than 85%.Thus,they are advisable in eletrolytic manganese industry.Although thick sulfuric acid increases the lixiviate rate,it is not advisable due to its corrosiveness.
