Semi-industrial Tests of Pressure Leaching on High-iron Sphalerite Concentrate

Wang Jikun,Zhou Tingxi,Wu Jinmei

Strategic Study of CAE 2005, Volume 7, Issue 1,   Pages 60-64

Abstract:

High-iron sphalerite was subjected to two-stage pressure leaching. The leaching rate of zinc and iron was 97.09 % and 15.2 % respectively. The yield of elemental sulphur was 93 % . The residual acid in the leachate was 3.95 g/L. By easy neutralization and purification, zinc sulphate solution was obtained, which would be sent to the zinc electrowinning operation. For the purpose of comparison, one-stage pressure leaching on average sphalerite was conducted. Leaching rate of zinc and iron was 98.09 % and 37.88 % respectively, and the yield of elemental sulphur was 96 % . The leachate with higher acid content (46.4 g/L) could be integrated into the existing traditional hydrometallurgical process of zinc

Analysis of factors affecting passengers ’ mountain sickness basedon nonparamertric tests

Chang Haijuan,Liu Meng,Pang Liping,Yang Peng,Wang Jun

Strategic Study of CAE 2009, Volume 11, Issue 2,   Pages 65-69

Abstract:

2 882 samples were taken in Qinghai- Tibet railway cars, and 1 693 samples were taken out randomly, then the factors that may affect the ability of individual' s hypoxia- resistant were analyzed in statistics. This paper has done this work by nonparametric statistics and correlation analysis , and got the conclusion that five factors, which are mountain sickness one have suffered before, sex, smoking frequency, bodily form and age, influence individual' s hypoxia- resistant ability. The conclusion makes a good sense, as it can provide statistics foundation for continuous iatrical research, while giving directive suggestion to reduce passengers' mountain sickness, and providing warranty for the design and amelioration of oxygen supplying system in Qinghai- Tibet railway cars .
