Thermodynamic modeling of lead blast furnace TAN Peng-fu(谭鹏夫) (Mount Isa Mines Limited, Queesland 4825, Australia) Abstract: A thermodynamic model was developed to predict the distribution behavior of Cu, Fe, S, O, Pb, Zn, As, and the heat balance in a lead blast furnace. The modeling results are validated by the plant data of a lead smelter in Kazakhstan. The model can be used to predict......

J. Cent. South Univ. Technol. (2008) 15: 835-839 DOI: 10.1007/s11771-008-0154-0 Recovery of indium and lead from lead bullion HE Jing(何 静)1, WANG Rui-xiang(王瑞祥)1, 2, LIU Wei(刘 维)1 (1...; Abstract: Lead and indium were recovered by electrolysis and nonequilibrium solvent extraction process from lead bullion. The effects of current density, electrolytic period and circle amount of electrolyte......
Preparation of lead sulfate powder directly from galena concentrates QIN Wen-qing(覃文庆), LIU Hui(刘 辉), TANG Shuang-hua(唐双华), SUN Wei(孙 伟) School of Resources Processing... is above 99% and its average crystallite size is about 42 nm. In this process, emission of lead vapour and SO2 cannot occur. The experimental results demonstrate the feasibility of realizing a green route......

Transformation behavior of lead fractions during composting of lead-contaminated waste LIU Jian-xiao(刘剑潇)1, XU Xiang-min(徐祥民)1, 2, HUANG Dan-lian(黄丹莲)2, ZENG Guang-ming(曾光明)1, 2 1... inoculants, which may be due to the more microbial biomass and the higher pH value in composting of Pb-polluted waste with inoculants. Key words: lead fractions; lead-contaminated waste; composting......
