摘要：

Using ultraviolet-visible spectrophotometry and laser and electron microscopy, adsorption of cyanuric triamide agent (CTA) at the surface of silver-rich galena PbS-Ag and pyrite FeS2-Ag is recorded. The X-ray spectrum of the new reagent phase on silver particles contains O, C and N bands typical of CTA. New experimental data on kinetics of selective flocculation of ultrafine particles of silver-bearing sulphide minerals under treatment by CTA and thermomorphic polymers (TMP) are obtained. It is found that CTA and TMP introduced jointly in sulphide slime pulp accelerate settling of slime fractions, which promotes mineral aggregation and improves flotation performance. The prospects of using CTA and TMP as modifiers in flocculation of slime fractions of silver-bearing minerals are demonstrated.
