Mitigating the negative effects of process water on recovering gold

点击翻译按钮获取中文摘要

Low quality water has been used in the minerals industry to save fresh water but shows harmful effects on gold extraction. This project aims to understand the interactions of organic and inorganic components, existing in process water, with gold and determine problematic components that inhibit gold extraction. Expected outcomes will be developed bio-sorbents, based on agriculture waste, that can remove the problematic components in process water efficiently and economically. This will provide major benefits for the minerals industry by providing options to respond and adapt to the impacts of water quality change, leading to increases in yield, revenue and growth of the precious metal sector whilst cutting poisonous chemical consumptions.
