concentration; frother type; entrainment; particle size; two-way ANOVA 1 Introduction Froth flotation is a separation technique applied to various types of ores using differences in the interfacial... on gangue recovery in froth was investigated. Effects of frother type and collector dosage on flotation performance were tested at pH 10. The results were evaluated statistically by two-way analysis......

SYNERGISTIC ACTIVATION OF CHELATING AGENT ON XANTHATE DURING THE FLOTATION OF REFRACTORY COPPER OXIDIZED ORES徐晓军,刘邦瑞摘 要:<正>Abstract:For realizing the effective flotation of refractory copper ox-idized ores and developing the activation-flotation theory ,the influencesof nine different organic chelating agents on xanthate collection power andits......
of butyl xanthate. The flotation tests of single mineral show that DMPS has strong depressing effect on pyrrhotite in the absence and presence of copper ion, but has activated effect on marmatite in the presence of copper ion. The floatability of marmatite is improved in the pH range of 2-12. The flotation test of mixture mineral shows that copper-activated marmatite can be separated efficiently......
and increases the amount of sulfur compounds produced in copper extraction processes. Therefore, selective separation of Cu/S by flotation is desirable. In the flotation of complex sulfide ores, high pH... with selectivity for chalcopyrite have been developed by many domestic and foreign scholars in recent years [15-16]. Dialkyl thionocarbamates are powerful collectors for the flotation of copper sulfide......
was developed which relates the flotation process to the image parameters, Nsne and Dagl of the froth and predictions are well consistent with the experimental data. Key words: sulphide ores; batch flotation...) (80g/t) as a collector and polypropylene glycol (100g/t) as a frother. Flotation experiments were conducted in an open top Leeds laboratory flotation cell with a capacity of 3L. Three impeller......
