    The objective of this study is to investigate the hygroscopic properties of the mixed lead concentrate (MLC) and recycle dust (RD) and to discuss the relationship between their hygroscopicity and microstructure. The hygroscopisity of MLC and RD was investigated by the moisture adsorption test performed over the temperature range of 25-85íŠ and relative humidity (RH) of 35-95%. The microstructure was investigated by the scanning electron microscopy (SEM) and the laser particle size analysis (LPSA). The results indicate that the equilibrium moisture content (EMC) of MLC and RD vary from 0.076% to 0.667% and 0.033% to 0.354%, respectively. Besides, the EMC of MLC is higher than that of RD under the same condition of RH. The changing trends of EMC for both materials are different which indicates that MLC and RD accord with different hygroscopicity rules. Moreover, the SEM results show that the microstructure of MLC tends to be more irregular and much rougher than that of RD. According to the LPSA results, the average particle sizes of MLC and RD are 5.319ŽIm and 2.657ŽIm, respectively, and the size distribution of RD particle is more homogeneous, which cause the different hygroscopic properties of the two materials. Lastly, two kinds of isothermal adsorption models are fitted to help predicting equilibrium moisture adsorption content of the MLC and RD during the production.
