“…Simultaneously, a globally increasing interest on topics such as sustainability, green chemistry and circular economy has emerged (Stahel, 2016;van Schalkwyk et al, 2018;Kinnunen and Kaksonen, 2019;Velázquez Martínez et al, 2019) and the implementation of more sustainable chemicals as well as reductions in environmental impact has since gained attention in the mining industry (Huang et al, 2019;Peçanha et al, 2019).…”

The mechanism of enamine on a quartz surface was investigated by pure mineral flotation tests combined with quartz surface wettability measurements, zeta potential tests and other analytical methods. The results show that the enamine flotation system had a quartz flotation pH range of 6.0-8.0 and a suitable collector concentration of 50 mg/L. Under neutral conditions, when the collector concentration was low, the enamine was adsorbed on the quartz surface through a weak electrostatic force. Semi-micelle adsorption occurred when the collector concentration reached the critical micelle concentration value of 10 mg/L. At enamine concentrations higher than 50 mg/L, multilayer adsorption of enamine and quartz occurred. The infrared spectroscopy results showed that no new peaks were formed before and after the interaction between quartz and enamine and that the enamine was mainly physically adsorbed on the quartz surface.

“…Depressants are a crucial factor in the flotation separation of valuable minerals from gangue minerals Huang et al, 2019 andChen et al, 2020). Previously studies have shown that talc and other Mg-bearing minerals can be depressed by polymeric depressants such as carboxymethyl cellulose (CMC), the carboxyl substituent groups along the cellulose chain (Shortridge et al, 2000;Parolis et al, 2008).…”

The effect of lizardite on talc flotation when using carboxymethyl cellulose (CMC) as a depressant was studied by micro-flotation experiments and adsorption measurements, zeta-potential measurements, magnesium ion dissolution analysis, and solution chemistry calculation. The results for the micro-flotation experiments showed that the addition of lizardite further decreased the floatability of talc at pH 8.5 when using CMC as the depressant. The mechanism was that magnesium ions dissolved from lizardite lattice, then formed hydrolyzed species of magnesium cations and interacted with talc surfaces, which promoted CMC adsorption, and thus decreasing talc floatability.
