  • Cationic flotation of quartz from an artificial mixture

    1988-1-1 · The cationic flotation of quartz was carried out from an artificial mixture (1:1 by weight) of fine grained ( − 10 μm) quartz and hematite, using hexylamine acetate (HAA) and dodecylamine acetate (DAA) as collectors. Selective flotation of quartz was possible in the pH range 9–10 using HAA.

  • Comparative studies of reverse cationic/anionic

    2011-9-14 · Obviously, the flotation of quartz in reverse cationic flotation is significantly faster than that in reverse anionic flotation. In reverse anionic flotation, even after prolonged flotation time, a small portion of quartz remains unfloated. Download : Download full-size image; Fig. 2.

  • Flotation and adsorption of quartz with the new

    2018-10-12 · 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 98.9%.

  • Separation of ultra-fine hematite and quartz particles

    2021-4-1 · Mixtures of the ultra-fine quartz and ultra-fine hematite could be treated at pH 9 by starch first, which selectively flocculated hematite, followed by PEO, which selectively flocculated quartz. The asynchronously flocculated slurry was then treated by a cationic collector such as DDA acetate that could float the flocculated ultra-fine quartz

  • Effect of Mn (II) on quartz flotation using

    2014-9-6 · Quartz is, in most cases, the major gangue mineral found in the manganese ore. Mn iron, dissolved from the surface of ore, will determine the interfacial properties of the particles and, thus, their flotation behavior. In this work, the effect of Mn2+ on quartz flotation was investigated through flotation tests. It was found that quartz can be depressed with Mn2+ and floated with dodecylamine
