Mechanisms for the improved flotation of inherently …
: It is well documented that unavoidable ions in a pulp such as Mg 2+, Ca 2+, and K + have a significant effect on the interaction for particles, especially for flotation of metallic sulfide minerals and clay minerals. In this study, the effect of electrolytes on the flotation of inherently hydrophobic mineral-graphite was studied. It was found that the …

Selective depressing mechanism of H-acid monosodium salt on flotation
Even if the HAMS dosage was increased to 6.0×10âˆ'3 mol/L, the flotation recovery of sphalerite remains above 90%. For graphite, its flotation recovery was very sensitive to HAMS dosage. When the dosage of HAMS increases to 1.0×10âˆ'3 mol/L, the recovery of graphite flotation decreases sharply to about 40.97%.
