FLOTATION MODE OF GOLD-CONTAINING ORES WITH THE TURNOVER OF ROUGH CONCENTRATE

Abstract

The study of the dynamic properties of a thin layer of water enclosed between solid surfaces made it possible to reveal the role of fluid adhesion and slip in their interaction. The resistance to approach of solids is presented in the form of corrections for sticking and sliding. The effect of sticking hydrophobic fine gold on thin plates and flakes of native gold was studied during the flotation of a charge composed of gravity tailings of gold ore (yield 98.187%, gold content 1.1 g/t) and heavy concentrate (yield 0.059%, gold content 49.88 g). /t), isolated by gravity from the waste ofplacer washing. It has been established that grains of finely dispersed gold are more strongly attracted to the surface of large gold particles (aggregation constant 43.7) than to each other (aggregation constant 0.070).
