The solidification of cyanide slag was carried out by different cementing materials as solidification agents.The results showed that the compressive strength of solidified body by modified magnesium oxysulfate cement(MOC) was better than those by portland cement(PC),aluminate cement(AC) and sulpho aluminate cement(SAC). The leaching rates of CN- from solidified bodies were in the order that RAC>RSAC>RPC>RMOC,and the accumulative leaching fractions of CN- from solidified bodies were similar to the leaching rates of CN-.Part of cyanide slag participated in the cementing reaction in MOC solidified system,which could increase the strength of solidified body and inhibit the leaching of CN-.
