中文摘要: 采用不同絮凝剂对电解锰锰矿浸出矿浆进行絮凝沉降试验，考察了絮凝剂电性、离子度、分子量以及添加量对矿浆絮凝沉降效果的影响。结果表明，矿浆含固率为6%时，添加60 g/t分子量1 400万~1 700万、离子度30%的阳离子絮凝剂，矿浆沉降速度由自然沉降时的0.04 m/h提高到0.69 m/h，能够满足电解锰行业制液工序生产要求。
Abstract:Sedimentation experiment for electrolytic manganese ore leached slurry was carried out with different flocculants. The effects of electrical property, ion ratio, molecular weight, and dosage of flocculant on sedimentation were investigated. The results show that settling velocity of leached slurry with solid content of 6% drops from 0.04 m/h of free settling to 0.69 m/h under the optimum conditions including 60 g/t cationic flocculant with molecular weight of 14 million to 17 million, and ion ratio of 30%, meeting the standard of pulp production process in electrolytic manganese industry.
keywords: flocculant manganese ore slurry settling velocity
