Cyanidation of a copper-gold ore - ScienceDirect

Effect of lead nitrate on gold leaching of a copper-gold ore. Pre-leaching: 30 min; cyanidation: pH 10.5, NaCN 710 mg/L, 02 15 ppm, 48 h. Pb(NO3)2 to 97.8% with 300 g/t Pb(NO3)2 (tests 4 to 6). The gold recovery remains the same for Pb(NO3)2 concentrations greater than 300 g/t (test 7).manganese ore gold cyanidation redox cameroon,manganese ore gold cyanidation redox cameroon manganese ore gold cyanidation redox cameroon Supergene gold mineralogy at Ashanti,Ghana CiteSeerXCyanide Leaching Of Gold - Mine Engineer.Com,The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve in 10-13 hours, while a 150 micron particle might take from 20 to 44 hours to dissolve in the same solution.
