Overview

Experimental analysis demonstrates dextrin's effectiveness in pyrite depression in sulfide copper ores, suggesting environmentally friendly applications.

Key Points

  • To evaluate the effectiveness of dextrin as a depressant in the flotation of a pyrite-containing sulfide copper ore.
  • Applied central composite design (CCD) for flotation experiments.
  • Optimized variables including pH, depressant amount, and collector amount.
  • Determined zeta potential values and sedimentation behavior.
  • Analyzed concentrates using SEM-EDS and FTIR.
  • Dextrin effectively depressed pyrite, aiding in the separation of chalcopyrite.
  • Zeta potential indicated increased surface hydrophilicity at high pH due to dextrin.
  • The resultant concentrate showed high copper and low silica and oxygen content.
