Abstract:

This paper introduces geography , geology and ore character of Jianchaling gold mine ,and analysis the experiment result . It discusses the technology including cyanidation ,flotation cyanidation and pretreatment cyanidation etc. Experiment study demonstrates : individual cyanidation is suitable for lesser enclosure of the gold ore ,leaching rate of 85 %;flotation cyanidation is fit for the sulfur bearing gold ore ,the total recovery rate of 82 %;pretreatment cyanidation is suitable for the high enclosure and low sulfur gold ore ,leaching rate reaching 90 %. It’s necessary to research novel pretreatment process to improve leaching rate of refractory ore further .

Key words: Jianchaling gold mine, gold ore, pret reatment , cyanidation
