【 摘 要 】

The paper presents the preliminary studies concern the results of Polish copper ore beneficiation in Jameson cell. To investigate the simultaneous influence of flotation machines type, grain size (0-25, 25-45, 45-75 μm), type (isobutyl and ethyl xanthate aqueous solution) and dosage (100, 150 g/Mg) of collector, flotation time on the efficiency of the process, the multi-level experiment has to be performed for carbonate lithological type of copper. Compering results of flotation test it can be concluded that the best results were obtained for 0-25 μm with the use of isobutyl xanthate aqueous solution in a dosage equal to 100 g/Mg. Tests of significance (MANOVA, ANOVA) showed a high influence of factors on the difference between an efficiency of separation in the most cases. This paper shows an attempt to create a model for the copper ore enrichment process at Jameson cell. The equations were described using a logarithmic substitution. The model evaluation was made based on mean squared error MSE and coefficient of determination R2.
