2022 5 1 The depletion of the hematite iron ore reserves >63% Fe of the Quadrilátero Ferrífero Brazil, in parallel to the growing demand for this commodity by the world market, led to the use of siliceous itabirites ∼30%–45% Fe by the mines located in this region. For a satisfactory performance of the reverse cationic flotation of
2021 8 15 The flotation processes performed in the main iron ore beneficiation plants located in the Iron Quadrangle region Brazil consist of flotation of natural fine particles below 0.15 mm, without grinding or flotation of all the material after grinding using ball mills run of mine . Utilization of humic acid as a depressant for hematite in
The flotation has been successfully applied to process the iron ore for the particle size Ps from 10 µm up to 150 µm. The presence of the slimes Ps 10 µm is harmful on the reverse flotation
2012 8 17 ABSTRACT Bauxite ore is the primary mineral resource for the production of aluminum metal and includes gibbsite Al OH 3, diaspore α AlO OH and boehmite γ AlO OH . Gangue minerals generally include iron oxides Hematite Fe 2O 3, Goethite FeO OH, silicates quartz SiO 2, kaolinite Al 2Si 2O 5 OH 4 and others such as
The main concentration method for iron ore enrichment is the reverse cationic flotation, in which the iron ore, typically hematite, is depressed Filippov et al., 2010 FILIPPOV, L. O.; FILIPPOVA, I.

2022 5 20 Abstract. Reverse cationic flotation is an important method for iron ore flotation. In this process, it is particularly important to find efficient, environmentally friendly and inexpensive hematite depressants. Hydrolyzed polyacrylamide HPAM, an inexpensive and environmentally friendly synthetic polymer organic reagent, was studied for the
