Some have been no than an extension of modern instrumentation for chemical analysis, as applied to specific flotation problems. But there has also been a number of simple yet illuminating experiments devised to shed light on particular flotation problems.
2020-7-14ensp0183enspCoal floatability evaluation is of vital importance in the prediction of flotation results and the design of a flotation flowsheet. In this work, a new experimental approach based on bubbleparticle attachment kinetics BPAK and bubbleparticle detachment kinetics BPDK were proposed to evaluate the floatability of coal particles. During attachment and detachment processes, a variation.
EXPERIMENTAL OBSERVATIONS ON THE FLOTATION OF MARINE DIATOMS. II.

To improve the recovery of copper from refractory copper oxidized ore by sulfidization-flotation process. The result determined the optimal flotation process parameters of refractory copper oxidized ore, and the better quota selecting separately obtained by a large number of research. The copper concentrate grade reaches 10.85, the recovery reaches 57.41.
All the experimental data validate the hypothesis that kaolinite covers molybdenite, reducing its flotation recovery. The depressing effect of kaolinite on molybdenite flotation in seawater is enhanced by the magnesium and calcium hydroxo complexes at pH gt 9, which induce heterocoagulation between kaolinite and molybdenite, thus reducing recovery.
