Study of the Technology for Gold Recovery from Gravity-Flotation ...
2022.6.13 Gold recovery during the combined gravity-flotation concentrate cyanidation using surfactants at a particle size of 89% 10 μm ( − 0.01 mm) is on average 81.6% compared with the use of TCCA—84.0% (average result for 3 tests). Reducing the concentrate size from 89 − 0.01 to 89% − 0.004 mm does not improve gold recovery.
