The Life Cycle of Water Used in Flotation: a Review
Zhang et al. investigated the effects of kaolinite on copper and gold flotation using both fresh and seawater. The results showed that kaolinite played a negative role in both copper and gold flotation in fresh water because of kaolinite particle aggregation, resulting in a lower copper and gold grade being achieved.
