Table 9 show flotation results of gold present in tailings at pilot scale with the 3PC column.Results showed a decrease in the flotation efficiency when increasing the air flowrate. Thus, for flowrates higher than 1.6 cm/s, a higher degree of turbulence was observed in the collection cell that led to a rupture of the floating bubble-particle aggregates

Feb 28, 2016 · Flotation feed grade was 0.006 to 0.01 oz/st Au with 0.1 to 0.3 oz/st Au column concentrate and 0.05 to 0.20 oz/st Au conventional concentrates. Recoveries ranged from less than 10 to approximately 50 pct. Gold recovery was complicated by: 1) CIL circuit operation, 2) the complex origin of the Au and 3) a complicated reagent scheme

fluidized bed adsorption columns, or directly to leached ore slurries by the addition of carbon to agitated slurry tanks, followed by separation of the carbon from the slurry by coarse screening methods. Gold cyanide is adsorbed into the pores of activated carbon, resulting in a process solution that is devoid of gold. The loaded carbon is heated by

Jul 13, 2016 · GOLD FLOTATION The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation

Conventional flotation using 60 minutes residence time across four roughing stages recovered about 97% of the gold into concentrates grading about 50 g/t Au. A single stage of column flotation roughing using 25 minutes residence time matched the conventional circuit recovery of 97%, but produced grades of+ 150 g/t Au
