EXPERIMENTAL STUDY ON MINERAL PROCESS OF FINE PARTICLE GOLD ORE

Experimental study on mineral process of fine particle gold ore was carried on.Base on the floatability experiment of grinding fineness and the orthogonal experiment of the reagent conditions,the best operating condition was confirmed.By close-circuit experimentations,it obtained gold concentrates containing 48.04 g/t with recovery of 85.63%.The results indicated that fine particle gold in the ore can be recovery effectively with sulfide minerals.
