A beneficiation test of high carbonate manganese ore was studied on the basis of study of the ore properties.When the joint flowsheet of high-gradient magnetic-reverse flotation of the high carbonate manganese ore was adopted,the manganese concentrate with the productivity of 21.75％,grade of 31.78％ and recovery of 45.84％ (the phase of manganese recovery is 81.78％.)was achieved through the high-gradient magnetic-reverse flotation closedcircuit test.It also gives some reference to the similar manganese.%本文在对某高碳酸盐型锰矿进行矿石性质研究的基础上,开展了选矿试验研究.结果表明,原矿经“高梯度强磁—反浮选”联合流程选别后,可获得锰精矿的产率21.75％,品位Mn 31.78％,回收率45.84％(对锰矿物相回收率81.78％),为同类锰矿的开发利用提供了借鉴.
