Experiment of Cyanide Leaching of Xianrenyan Surface Gold Ore

FU Chou-lin

Abstract

Three cyaniding leaching methods were compared based on characteristics and chemical composition of Xianrenyan surface gold ore.The effects of pretreatment of ore,particle size,blasting and stirring,and roasting on gold leaching rate were investigated.The results show that heap leaching is the reasonable method for Xianrenyan gold ore with the advantages of low cost and large handling capacity.
