Abstract: A refractory silver ore in Hebei province contain various silver minerals and which dissemination characteristics are complex.Based on the study of technological mineralogy and scheme comparison,obtain the flotation and cyaniding the flotation tailings combined process.Study on influence factors to silver recovery rate in flotation experiment,which include the grinding fineness,pulp pH value,combined collector of butyl xanthate,the dosage of FZ-9538 and so on.The optimum technological conditions are determined.The closed circuit test can get the silver concentrate which of grade is 3145g/t and the recovery is 82.52%;Flotation tailings silver grade is 42g/t,after 24 hours cyanide leaching,the silver leaching rate is 65.48%,the recovery rate to raw ores is 11.45%.Both flotation and cyanide experiment,the silver recovery rate is 93.97%.
