The phenolic content present in leaf extract can easily donate electron to hydrogen peroxide and thereby neutralising it into water (Lateef et al. 2017 ). The hydrogen peroxide-scavenging assay at different concentrations of green-synthesised Ag–TiO 2 NCs and TiO 2 NPs were investigated (Fig. 10 ).
As a result, an ilmenite concentrate is obtained with a titanium dioxide concentration of at least 50 % and a beneficiation degree of 49 %. Such a concentrate can later be used in the process of chemical processing to obtain titanium and its various compounds.
