  The Challenges and Prospects of Recovering Fine Copper …

  202256 · Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

  The Challenges and Prospects of Recovering …

  199281 · The results of an investigation to characterize the chalcopyrite/solution interface are presented. Several techniques were used, including galvanostatic and steady-state polarization, cyclic voltammetry and impedance spectroscopy. The results show that the dissolution of chalcopyrite was incongruent. Initially, at low potentials (< 0.12 V), iron …
