Xanthate Sorption and Floatability of Sphalerite

Basic Study on Flotation of Sphalerite, 3rd Report

Abstract

Floatability of copper- or silver-pre-activated sphalerite in potassium ethyl xanthate solution was studied. Furthermore, the thickness of the hydrophobic layer formed on the surface of the samemineral was estimated from the iodometric measurements of the concentrations of the xanthate before and after the flotation. The results thus obtained were compared with those of the electron diffraction investigations described in the first and second reports of this research.
