Improving Flocculation Performance of Copper Flotation …
Large amounts of tailings are produced when copper minerals are concentrated by flotation. For instance, the flotation process is performed with water containing 25–35% wt solid ratio and is consumed 1.9–3 m 3 water per ton of ore processed (Gunson et al., 2012; Li et al., 2019).
Hydrophobic-surface of copper from converter slag in the flotation system
Flotation tests show that, Z-200 butyl xanthate and butylamine dithiophosphate all have good collecting ability on copper. At the concentration of 0.7 × 10 −4 mol/L, the recoveries are all more than 85%. Z-200 has the best flotation result but in alkali environment its flotation results become worse. (2)
