Dec 20, · G flotation. The Froth Flotation Method is means separating minerals according to their different physical and chemical properties. According to classification, the flotability of g and silver minerals is included in the first category of natural and nonferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate collectors.

Apr 03, · Flotation of ultrafine chalcopyrite can be improved by processing the ore with (1) splitcircuit design and (2) intense agitation conditioning before flotation. At equivalent or even lower collector consumption, a split circuit flotation design, treating the plus 38 and minus 38µmsize ore individually, recovered 93 pct of the copper in a 28.7pctcopper concentrate.

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

3.1. Flotation Fig. 1 shows the recoveries of chalcopyrite and pyrite as a function of flotation time in copper flotation. Lime was used to increase pH to 9.5 in flotation to depress pyrite. It can be seen that chalcopyrite was selectively floated from pyrite with about 90% chalcopyrite recovery and only 4% pyrite recovery.
