flotation tests of manganese ore were carried out to investigate collecting performance of the novel synthesized lha compound. the samples were ground to 90% passing 74 μm. the pulp was conditioned at 25 wt.% solids in an xfd-type laboratory flotation cell with a volume of 0.75 l for 3 min and the impeller speed was fixed at 2000 rpm.
manganese ore beneficiation technology low grade manganese ore cannot be directly used in industrial production due to high impurity content thus there is a need for a method of enriching low grade manganese ore. manganese ore processing is the process of separating valuable minerals from impurity content by physical or chemical properties.
manganese ore concentration by flotation. the slime fraction of the ore overflowed by the hydraulic classifier and by the rod-mill spiral classifier is thickened in a spiral rake tray thickener for treatment by flotation. the flotation circuit is designed to treat three classes of manganese ores. those ores with a high calcite gangue.
many of them can be exploited a cheap beneficiation process will be required. test work on a sample of ore from a low-grade deposit in s.w. viti levu showed that a marketable manganese concentrate could not be produced from this ore by gravity concentration or flotation even though a low manganese recovery may be acceptable.
