Physico-chemical Models of Optimal Conditions for Galena Flotation
The interaction and galena flotation with xanthenes and dexanthogen regularities have been defined. So, using thermodynamic method of analysis, the thermodynamic stability of galena-xanthenes-water system and the behavior of lead xanthenes surface state in solution were devised.Thus, results of eared out calculations and experimental investigation completely coincide without depending on witch product of sulfur oxidation is formed in the solution. In additional, was obtained quantitative physico-chemical models for the necessary xanthenes concentration of lead sulfide complete flotation in the tuning fork of: at pH values from 7.0 up to 9.0 (or at the formation of lead carbonate PbCO3) and at pH values from 9.0 up to 12 (or at the formation of lead hydro carbonate Pb3(OH)2(CO3)2.Physico-chemical models derived can be used as the criteria for functional units of automation systems to control and regulate the flotation process in mineral processing plants.
