New reagents for controlling of H2O2 by metal sulfide and its effect in sulfide mineral floatation [PDF]
International Journal of Mining and Geo-Engineering, 2021 Our recent studies revealed that the ground sulphide minerals in contact with water generate H2O2 but its effect on the oxidation of pulp components and hence in deteriorating the concentrate grade and recovery in flotation has not been explored yet. The

Hematite and quartz microflotation using millet starch as depressant
REM: International Engineering Journal, 2021 Brazil is among the world's largest iron ore producers. The standard concentration method is reverse cationic flotation using amines, and their derivatives, such as quartz collector and corn (as either grits, flour, or starch) as the hematite depressant.

Investigations on the Reverse Flotation of Quartz/Hematite Using Pullulan as a Novel Depressant
Metals, 2023 The traditional hematite depressant starch has the disadvantages of poor solubility and high viscosity. In this study, a novel hematite depressant, pullulan, with better performance and flotation effect than starch was found.
