“…As common-used collectors, amines have been widely used in the flotation of nonsulfide system, such as silicates (quartz (Li and De Bruyn, 1966;Novich and Ring, 1985;Takeda and Usui, 1987;Smith and Scott, 1990;Fuerstenau, 2005;Ata and Yates, 2006), muscovite (Herder et al, 1987;Nishimura et al, 1992;Nishimura et al, 2000), feldspar (Hanumantha and Forssberg, 1997), lepidolite, kaolinite Hu et al, 2005), illite (Zhong et al, 2008), pyrophyllite (Zhao et al, 2003)), metal oxides (bauxite (Wang et al, 2004), zirconia, goethite and corundum (Fuerstenau. 2005)), sylvite (Monte and Oliveira, 2004;Cao et al, 2010), etc.…”

“…There are many studies addressing the concentration of Chinese bauxites (Hu et al, 2003;Zhao et al, 2003;Yuehua et al, 2004, Wang et al, 2004Xu et al, 2004;Zhang et al, 2008b). The main aluminium-bearing mineral in Chinese ores is diaspore.…”

This paper presents a potential condition to separate kaolinite through flotation when it is present in bauxite ore. This research anticipates a Brazilian industry requirement, considering the tendency towards the need for aluminosilicates removal from bauxite ores, as has already occurred in China. Kaolinite is the most abundant aluminosilicate, and gibbsite is the main aluminum bearing mineral in Brazilian bauxite ores.The first step was a fundamental study involving microflotation experiments with pure samples of kaolinite and gibbsite. Ammonium quaternary salts and amines were used as the collector and corn starch as the depressant.In a fundamental study, the best conditions determined in the first step were evaluated for the flotation of kaolinite from bauxite ore using laboratory scale experiments. Tests with AQ142/starch (pH 10) and CTAB (pH 7) led to satisfactory results. In general, the highest values of alumina/silica mass ratio were obtained with AQ142/starch and the highest values of mass recovery and metallurgical recovery were achieved with CTAB.

“…In iron ore processing, the reverse flotation of silica and silicates has been tested successfully by both cationic and anionic reagents to obtain purified ferriferous concentrates (Houot, 1983;Ma et al, 2011;Pradip et al, 1993;Pradip, 2006). Much work regarding the reverse flotation of diasporic ores has been reported which involve the effective flotation and collection of alumina-silicate gangue minerals such as pyrophyllite, illite, kaolinite and chlorite using cationic reagents like alkyl amine and carboxy hydro-oxidoxime (Xu et al, 2004;Wang et al, 2004). For phosphate rocks, direct flotation is sometimes ineffective due to similar physico-chemical properties of phosphates and carbonates (Gharabaghi et al, 2009;Kawatra and Carlson, 2013;Sekhar and Jain, 2009).…”
