Effects of operating variables on modified flotation

Abstract An attempt has been made in this paper to investigate effect of collector type, particle size distribution, collector dosage, air flow rate, pulp density and wash water rate parameters on modified flotation parameters on sphalerite flotation in a flotation column. In the experimental studies, the fractional recoveries after 0.5, 1, 2, 3, 5, 10 and 20 min of flotation time were fitted

Abstract A specially designed mill which allowed the control of pH throughout grinding was used to study the effect of grinding conditions on chalcopyrite flotation and chalcopyrite separation from pyrite. The mechanism of galvanic interaction between minerals and grinding media was investigated by ethylene diamine tetra acetic acid disodium salt EDTA extraction and X ray photoelectron

Jun 08, 2016· In practical operation the function of promoters may be considered two fold: namely, to collect and select. Certain of the xanthates, for instance, possess both collective and selective powers to a high degree, and it is reagents such as these that have made possible some of the more difficult separations.
