摘　　要：对氧化锰矿电化学阴极处理，可明显改善氧化锰矿的可浮性。在ｐＨ值８．５，电化学作用时间５ｍｉｎ以及电压１５Ｖ条件下，获得了较理想选别指标。较之未经电化学处理的常规浮选，其精矿产率γ、回收率ε分别提高１１．３０和２０．４９个百分点。Floatability of manganese oxide ore is obviously improved by electrochemical cathodic treatment. Under pH 8.5, electrochemical reaction time 5 min and electric pressure 15V, ideal beneficiation index is obtained. Concentrate yield and recovery are respectively increased 11.30% and 20.49% and concentrate grade is increased about 2% than traditional floatation untreated by electrochemistry.
