At present,there are a lot of ways of comprehensive utilization of the tailings.But they only use it to produce concrete block,sheet metal,cement and other materials,not fully utilizing tailings’composition,which contains enonnous of SiO2 and A12 O3,not extremely be used.We introduced the current ways of comprehensive utilization of gold tailings in this article,on the basis of preliminary exploration of gold:Takes the flux by K2 CO3,through high temperature calking decomposition gold tailings,the resultant was resolved in water,acidified by CO2,the residue was removed by filtration and the remaining solution was prepared potassium carbonate and white carbon black,the residue was acidified by H2SO4 firstly and prepared A1(OH)3.

Key words: Gold tailings, Calcinations, Comprehensive utilization, Flux
