1.16: Methods for Separating Mixtures
Filtration is a separation method used to separate out pure substances in mixtures comprised of particles—some of which are large enough in size to be captured with a porous material. Particle size can …
A reagent scheme for galena/sphalerite flotation separation: Insights
This manuscript comprises two parts. In the first part, flotation was adopted to separate galena from sphalerite-rich sulphide ore. In the galena/sphalerite flotation, aerofloat was used as the collector to replace xanthate, and Zn 2+ and SO 3 2− were combined to depress the sphalerite flotation.
Flotation Processes: A Review
Flotation is a separation mechanism engaging numerous interconnected sub-processes, the collective operation of which determines its overall success. The complexity and interrelationship of various factors involved directly impact the development of a successful prediction model [3]. A satisfying system of controlling flotation is …
