Multivariate modeling and optimization of the reverse …

In the cationic reverse flotation of iron ore at alkaline pH (9 to 10.5), gelatinized starch with NaOH is used as an iron ore depressant (Silva et al., 2019). In this process, a desliming step must be applied to remove particles below 10 µm, which can result in large mineral losses ( Gonçalves and Lima, 2020 ).

Developments in the physiochemical separation of iron ore

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 …
