Iodide-assisted leaching of chalcopyrite in acidic ferric sulfate media
TLDR
In this paper, the authors investigated the use of potassium iodide to assist chalcopyrite leaching and proposed mechanisms by which iodide enhanced the leaching efficiency, showing that tri-iodide might play a significant role in leaching enhancement.About:

Effect of Ultrasound on the Oxidative Copper Leaching from Chalcopyrite in Acidic Ferric Sulfate Media
TL;DR: In this article, the reaction kinetics of copper leaching from chalcopyrite in acidic ferric sulfate media with (UAL) and without (non-UAL) ultrasound assistance were compared.
Journal ArticleDOI
Kinetic modelling of chalcopyrite leaching assisted by iodine in ferric sulfate media
TL;DR: In this paper, the effect of different parameters on the kinetics of copper extraction in the presence of iodine and elucidated the possible rate-limiting steps were quantified and the authors showed that redox potential was the principal factor determining the leaching performance via controlling the aqueous iodine speciation.
