This article studied on calcium ions affecting mechanism to collecting quartz in the system of dodecyl sulphate. Studied calcium ions on Zeta potential of quartz surface and flotation behavior through flotation experiment, Zeta potential measurement, infrared spectroscopy and solution chemistry of calcium calculation. The results show that the ability of collecting quartz by anionic collector dodecyl sulphate is weak within pH range of 4-14, and basically can be seen cannot collect quartz. When adding calcium ions, the capacity of collecting quartz increases significantly. By Zeta potential of quartz surface, when pH>2, Zeta potential of the quartz surface shows negative charge, is not conducive to the adsorption of the anionic collector dodecyl sulphate. When adding calcium ions, Zeta potential increases significantly, and at pH = 10, Zeta potential begin to rise sharply, at this point, the concentration of Ca(OH)+ in the solution composition of calcium is also started to increase, and the recovery rate of the quartz begin to increase sharply. The concentration of Ca(OH)+ is the maximum within pH=11.5-13.5, and Zeta potential of quartz surface shows positive charge, and the recovery rate of the quartz is corresponding to the maximum. So can be determined, Ca(OH)+ is the main reason of affecting Zeta potential of the quartz surface, and Ca(OH)+ is the main active ingredient that activate flotation of quartz in the system of anionic collector dodecyl sulphate.
