Developments in the physiochemical separation of iron ore

Jan 01, 2015· Table 11.1 shows the points of zero charge (pzc's) for some iron oxides and quartz (Aplan and Fuerstenau, 1962).This property is important when using flotation collectors that are physically adsorbed, for example, amines. The pzc's for the three iron oxides, hematite, magnetite, and goethite, are around neutral pH (~ pH 7), whereas the pzc for quartz is in the acidic region (~ pH 2).
