| Abstract: | The floatation concentrates of cyanidation tailings was very refractory,for which the dissolution of gold by NaCN for leaching 24 h under the grinding size of <37 μm of 99.5% was only 3.95%.After the pre-oxidation of intensified alkaline leaching under normal temperature and pressure,the dissolution of gold by NaCN was enhanced to 85.85%,and the adsorption recovery by activated charcoal was 99.62%. |
