Surface Characteristics and Flotation Behaviour of Low-Grade Manganese Ore

Abstract:

Evaluation possibility of low grade manganese mineral from Hunan by froth flotation technique was investigated. Manganese mineral sample was characterized with mineralogical analysis, XRD, and SEM studies for its mineral content and surface characteristics. XRD analysis showed that the gangue contents of manganese minerals are constituted mainly by dolomite as a carbonate mineral, quartz and feldspar. SEM indicated that existence of rhodochrosite, which mainly fills in the dolomite minerals. The influences of important factors on manganese mineral flotation are investigated. The size of grind, pulp pH, dosages of depressant and collector are essential to the effective recovery of rhodochrosite in manganese mineral flotation.
