Abstract

By single mineral experiments actual ores test , potentiodynamic tests , infrared spectroscopy , particle size testing and solution chemistry calculation and thermodynamic calculations , the smithsonite the basic flotation behavior as well as the collector , mineral dissolution , pH adjusting agent , and smithsonite flotation behavior and its mechanism of metal ion adsorption of complex components , the transformation of the nature of the solution interface reaction with mineral surfaces and flotation association . The main conclusions of the paper are as follows : a single mineral experimental results show that significant collector dosage and pulp pH smithsonite flotation impact ; anionic collector OL-4 flotation flotability better pH range 7 -9; dissolved interested Ling the flotation of the zinc blende adversely affect the removal of the dissolved component in the pulp on the flotation advantageously ; of Na2CO3 do pH adjusting agent will be reduced to dissolve the smithsonite flotation adversely affected ; Zn2 , Ca2, Mg2, Pb2 activation Ling zinc ore flotation , Fe3 suppression smithsonite flotation . The potentiodynamic and infrared spectra of the test results , the anionic collector OL - 4 smithsonite surface chemical adsorption ; the granularity test results show that the collecting agent OL-4 smithsonite fine particles hydrophobic agglomerates . \Actual ore test results show that the refractory ore, the ore grade of 6.91% Zn Xinjiang oxidized lead-zinc and the process desliming can get the oxidized ore concentrate grade of 20.53% Zn Zn recovery rate up to 73.20 %.
