Reference number : GC-2017-Q4-01510, amendment number : , agreement type : G, recipient legal name : Rakshit, Sudip (Lakehead University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Gold ore processing includes crushing, grinding, leaching by cyanidation, carbon in pulp recovery and_x000D_
electrowinning. This method is one of the major gold separation procedures used by most such industries._x000D_
Interference of other metal ions in the ore in upstream and downstream processes has a significant effect on the_x000D_
production process efficiency. A substantial amount of heavy metal ions is present in the downstream (tailing)_x000D_
process. This has been identified as a challenge that needs to be overcome. Selective removal of the metal ions_x000D_
from the gold ore in the upstream process before leaching or after leaching will significantly improve gold_x000D_
quality. Separation of these metal ions can lead to a by-product of economic value. We plan to develop and use_x000D_
novel adsorbents that can specifically recover valuable metals from solution containing mixture of metal ions._x000D_
Selective recovery of some metal ions from the production line of gold ore will also improve the processing_x000D_
and cost of production. It will enhance the yield and the quality of gold. Interfering metal ions removal before_x000D_
leaching or immediately after leaching before refining will enhance gold recovery and will lead to additional_x000D_
revenues for the company and the local economy as these metals have a market of their own. The planned_x000D_
procedure will also improve the quality of the effluents from the wastewater treatment. In this study, novel_x000D_
environmentally friendly adsorbents capable of selective adsorption of heavy metal in a complex mixture of_x000D_
metal ions will be developed. The Musslewhite unit of Goldcorp is very keen to address interfering metal ions_x000D_
issues to increase the efficiency of their process and potentially derive financial benefits from the same. Our_x000D_
preliminary studies have shown the novel adsorbents to be effective on laboratory model samples., program purpose french : Gold ore processing includes crushing, grinding, leaching by cyanidation, carbon in pulp recovery and_x000D_
