  • Starch chemical modification for selective flotation of

    Sep 01, 2020· Ideally, as a depressant native starch must not interact with both valuable copper sulphides and carbon gangue to achieve selective flotation Therefore, through specific starch modification which entails molecular size changes and insertion of new chemical groups, desirable qualities of the derivatives can be anticipated ( Chen et al, 2003 )Oct 01, 2019· Copper sulphides flotation at high pH values with sulphide ores using traditional collectors are economically beneficial but at the same time this also decreases the recovery of associated rare and precious metals (Zhong et al, 2015) Bench scale flotation experiments were performed at natural pH (pH 82) to investigate the recovery of copperComparison of single and mixed reagent systems for
