摘要

The tailings from Huangyan Lead and Zinc Mill mainly contains quartz，mica，illite and aluminous minerals，一whichis full of promise to be used for raw porcelain material to substitute feldspar，but its Fe₂O₃ and MnO content are 6.66% and 7.37% respectively，much higher than the fixed level (Fe₂O₃+MnO<1.5%). By using magnetic separationtechnique，the Fe₂O₃ and MnO content can be，reduced to 1.05% and 0.42% respectively. The processed tailings forporcelain material can make porcelain formation temperature reduce by about 100℃.Morever the comprehensive uti-lization of the Pb and Zn tailings can avoid tailings being piled up，thus eliminating environmental pollution。
