Gold ore processing includes crushing, grinding, leaching by cyanidation, carbon in pulp recovery andx000D
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 thex000D
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 ionsx000D
from the gold ore in the upstream process before leaching or after leaching will significantly improve goldx000D
quality. Separation of these metal ions can lead to a by-product of economic value. We plan to develop and usex000D
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 processingx000D
and cost of production. It will enhance the yield and the quality of gold. Interfering metal ions removal beforex000D
leaching or immediately after leaching before refining will enhance gold recovery and will lead to additionalx000D
revenues for the company and the local economy as these metals have a market of their own. The plannedx000D
procedure will also improve the quality of the effluents from the wastewater treatment. In this study, novelx000D
environmentally friendly adsorbents capable of selective adsorption of heavy metal in a complex mixture ofx000D
metal ions will be developed. The Musslewhite unit of Goldcorp is very keen to address interfering metal ionsx000D
issues to increase the efficiency of their process and potentially derive financial benefits from the same. Ourx000D
preliminary studies have shown the novel adsorbents to be effective on laboratory model samples.
