2021-9-15  How to sustainably produce bauxite by effective reverse froth flotation of kaolinite at low temperature is an urgent problem to be solved in the field of mineral processing. In this work, a novel amino-based Gemini surfactant butadiyl-1, 4-bis (dimethyl dodecylammonium bromide) (BBDB) was prepared and first utilized as a novel collector for

Flotation enhancement of low-grade bauxite using oxalic

2021-11-20  Surface pretreatment of low-grade bauxite using oxalic acid was carried out prior to the flotation experiments. 500 g of bauxite samples with a 60% pulp density was firstly ground to 85% < 0.075 mm. After the slurry was transferred to a beaker, a certain amount of oxalic acid solution was added to keep its concentration of 0.01, 0.05, 0.5 mol/L.

THE FLOTATION OF MARGINAL GIBBSITIC BAUXITE

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 rutile/anatase [TiO 2].

Kaolinite removal from bauxite by flotation SciELO

1. Introduction. Chinese bauxite ores have required more elaborated beneficiation processes than the Brazilian bauxite ores. This fact is a consequence of the low alumina/silica (Al/Si) mass ratio in currently mined Chinese ores (Xu et al., 2004 XU, Z., PLITT, V., LIU, Q.Recent advances in reserve flotation of diasporic ores A Chinese experience.
