natural floatability and collectorless flotation of

Abstract. This chapter first explains the natural flotability of some minerals in the aspect of the crystal structure and demonstates the collectorless flotaiton of some minerals and its dependence on the E h and pH of pulp. And then the surface oxidation is analysed eletrochemically and the relations of E h to the composition of the solutions are calculated in accordance with Nernst Equation

zeta-potential and flotability of the scheelite mineral in

It was found that the flotability of mineral scheelite depends on the hardness and electro-conductivity of the chosen type of water as well as on Ca2+ content. Also, it was found the floatability of mineral depends on the scheelite particle size fraction used in microflotation experiments. ... Adams, R.W., i dr. (1986) Mining chemicals handbook
