Quartz-Calcite-Hematite System Flotation

2020-7-18  The flotation of hematite from a mixture of quartz and hematite (Figure 5) was almost unchanged from its flotation behavior alone. There was a smaller quantity of hematite present than when floated alone and, if quartz adsorbed no collector, the widening of the pH flotation range on the alkaline side might be expected.

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%.
