Replacing Dichromate with Polysaccharide Depressant in Cu

Aug 27, 2021· Up to10%cash back· However, in Chinese flotation plants, it is rarely used in complex sulfide sequential flotation. Competitive adsorption and surface cleaning are important for sequential flotation. Liu and Zhang found that at high pH if using sodium hydroxide as a pH modifier, galena could be depressed by dextrin but not chalcopyrite with xanthate collector. If using lime as a pH modifier or adding calcium cations alone, chalcopyrite was depressed because calcium adsorbed on the chalcopyrite
