Studies on the Interaction of Guar Gum With Chalcopyrite

Adsorption of biosolids and their main components on chalcopyrite, molybdenite and pyrite: Zeta potential and FTIR spectroscopy studies

“…The IEP of the chalcopyrite sample used in this investigation is close to the value reported by other researchers, namely around pH 3.0 (Rath et al, 2001). However, Mitchell et al (2005) have reported an isoelectric point at pH 5.5 for a chalcopyrite sample containing 65% chalcopyrite.…”

“…Compared with the well-known electrokinetic behavior of oxides, that of sulfide minerals is less well understood, and different isoelectric points (IEP) are reported in the literature. In the case of chalcopyrite, for example, an IEP at around pH 3.0 has been reported by Rath et al (2001), but Mitchell et al (2005) have reported an isoelectric point at pH 5.5 for a chalcopyrite sample containing 65% chalcopyrite. For pyrite, Mitchell et al (2005) and Patra and Natarajan (2006) have reported an isoelectric point at a pH between 2 and 2.5.…”

A study of the relative adsorption of guar onto pure minerals

“…In a study on the interaction of guar gum and chalcopyrite, Rath et al (2001) found that conductivity and co-precipitation tests confirmed metal ionguar gum complex formation in the bulk solution. Thus these authors proposed that the interactions between guar gum and chalcopyrite involved the dissolution of the mineral.…”

Reactivity recovery of guar gum coupled mZVI by means of enzymatic breakdown and rinsing

“…starch, dextrin, guar gum and carboxymethyl cellulose) and mineral surfaces has been studied widely (Laskowski et al, 2007;Lin et al, 2010;Liu and Laskowski, 1989;Liu et al, 2000;Ma and Pawlik, 2007;Rath et al, 2001). To further explain the stabilization mechanisms and adsorption configuration between Fig.…”
