Investigation of the Attenuation and Release of Cu2+ Ions by Polymer-Treated Tailings

This study investigated the attenuation and release behaviour of copper ions using a standard kaolin-silt slurry as synthetic tailings in high solids/high salinity application before after inline flocculation. A homogenous, was prepared 0.6 M NaCl solution treated low-shear mixer by adding Magnafloc® 336 flocculant. Following evaluation morphological properties both untreated (UT) polymer-treated (PT), identical equilibrium tests were performed via bottle-point method constant concentration technique. The maximum uptake capacity 25% more than at state chemisorption process which had capability binding onto one location on sorbent, could be influencing other sites same sorbent. Polymer treatment resulted highly porous structure that exhibited an increased to adsorb retain compared UT materials. indicates strong between active site particles with greater this material for preserving heavy metal within their across wide pH range (2–10) results advance fundamental understanding how flocculation can considerably improve sorption favouring potential long-term rehabilitation purposes mine closure role desorption ions’ play achieve goal.
