Fig. 3 Magnetic recovery of α-Fe 3 O 4 (a) and γ-Fe 2 O 3 (b) from the concentrates after rod milling;
and recovery of goethite precipitates in the cycle use of α-Fe 3 O 4 (c) and γ-Fe 2 O 3 (d)
study provides a feasible way to convert a hydrometallurgy waste of zinc hydrometallurgy to value-added raw materials for the ironmaking and production of building
materials. An array of techniques has been used to characterize the goethite formation on MNPs and the results showed that γ-Fe 2 O 3 is superior to α-Fe 3 O 4 for the
formation of goethite particles on its surface.
