Abstract: There is 26.41% Fe and 0.67 g/t Au in a low grade specularite ore from Shanxi.Gold mainly exists in form of natural gold，natural gold accounted for 88.15% of total gold.Iron mainly exists in form of hematite-specularite，hematite-specularite iron accounted for 68.28% of total iron.To recovery valuable elements Au and Fe，preferential flotation of gold，flotation tailings low intensity magnetic separation-high gradient magnetic separation-reverse flotation to recovery iron process was conducted.Results indicated that，at grinding fineness of -0.074 mm 83.78%，using lime as pH regulator，sodium silicate as dispersant，butyl xanthate + butylamine aerofloat as collector，2# oil as frother，via one roughing two cleaning two scavenging gold flotation，gold concentrate with 29.31 g/t Au and recovery of 87.93% was obtained，gold tailings via one roughing one cleaning one scavenging low intensity magnetite separation，iron concentrate 1 with 65.86% Fe and recovery of 13.34% was obtained，low intensity magnetite separation tailings via one roughing one scavenging high gradient high intensity magnetic separation，high intensity magnetic separation concentrate using NaOH as regulator，modified starch as depressor，sodium oleate as collector，via one roughing two cleaning one scavenging reverse flotation iron，iron concentrate 2 with 61.79% Fe and recovery of 50.67% was obtained，mixed iron concentrate combined by iron concentrate 1 and iron concentrate 2 with 62.59% Fe and recovery of 64.01% was obtained.Test results can provide technical basis for comprehensive recycle of valuable elements.
