cationic flotation of fine quartz

of Quartz by - Columbia University

Flotation of quartz at pH 6.5*0.5 is given in Figure 1 as a function of dodecylarnine hydrochloride concent~ion. It is. 6 seen that amine causes flotation but interestingly, use of excess amine causes a depression. The flotation obtained at lower concentrations is in agreement with the expected electrostatic adsorption of the cationic amine surfactant on the quartz particles that are ...
