flotation process of quartz

Towards a new process for the flotation of quartz ...
2015-11-1 · The process described in this study represents a third use of HF, in which the chemical is employed to produce a directly floatable quartz surface. HF in aqueous solution is a weak acid, and only some 10% is dissociated in a 0.1 N solution ( Sidgwick, 1950 ). However, the dissociation constant falls continuously with dilution.
