the flotation performance recognition in sulphur flotation process. GUI et al [11] proposed a texture feature extraction method based on color co-occurrence matrix to better monitor and evaluate the production state. Recently, based on GUIs' work, ZHAO et al [3] presented a multi-scale gray level

Surface sulfidization mechanism of cuprite and its

We further improved the flotation recovery of cuprite with a moderate increase in the concentration of sulfide reagents. The flotation recovery of cuprite reached 47.41% at 1 × 10 −3 mol/L Na 2 S and 2 × 10 −4 mol/L NaBX. This may be attributable to the formation of additional hydrophobic copper sulfide components on the cuprite surface.

The iron purity rose 15.6% on average from 56.22% to 65.03%, corresponding to an average decrease in silica purity from 14.77% to 2.32%. In addition, a stabilizing flotation performance was registered by comparing the fed purity dispersions and concentrated purity dispersions for both iron and silica.
