Towards a new process for the flotation of quartz

01-11-2015· Flotation is an indispensible tool in the production of high purity quartz concentrates for such uses, as most of the contaminating minerals can be floated with the appropriate collectors leaving the purified quartz behind in the sink fraction.

Flotation of quartz particles assisted by nanobubbles

10-04-2015· Flotation. The flotation of quartz was conducted with classified-sized fractions and with the composite samples, prepared by blending all the quartz fractions studied as described in Table 2. Thus, flotation tests were carried out with different setups: i. Flotation with coarse bubbles in a Hallimond tube; ii.

The flotation of quartz from iron ScienceDirect

01-10-2005· The flotation of quartz from magnetite can be completed by using CS-22 only, but the quebracho should be used as a depressant in the flotation separation of quartz from specularite. (3) CS-22 is preferred to adsorb on the surface of quartz, changes its zeta potentials and contact angles, and increases its hydrophobicity.

Non-HF collectorless flotation of quartz ScienceDirect

15-03-2019· There was no flotation of quartz in pure water, with only frother, or with NaF and frother. Quartz started to float when it was treated with H 2 SO 4 and frother, and with H 2 SO 4, NaF and frother. The recovery of quartz increased with the increase in the concentration of H 2 SO 4 and NaF.
