Flotation and adsorption of quartz with the new collector

Oct 12, 2018 A new surfactant butane-3-heptyloxy-1,2-diamine [CH3(CH2)6OCH(CH3)CH(NH2)CH2NH2; BHLD] was synthesized. It has been innovatively used as a collector in the flotation of quartz. In this present study, the flotation behaviors of quartz with BHLD were investigated by micro-flotation of quartz. It was found that the recovery of the quartz reaches

Finally, the geometric optimization of the cervantite and the quartz (001) plane was performed. In the optimized lattice, after geometric optimization, water molecular, DDA ion and

Developing Effective Separation of Feldspar and Quartz

Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = 2.1).It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz [].However, there is a large amount of chemical activator (HF or NaF) in the flotation system, as
