粗铅冶炼过程中砷镉铊的走向分布及治理措施

在粗铅冶炼工艺中,铅精矿和其他含铅物料中的砷、镉、铊分布于各工序环节,不利于有价金属资源的回收,而且加大了冶炼废弃物的处理难度,另外还对人体健康和环境造成负面影响。现有文献对于砷、镉、铊在粗铅冶炼过程中的分布及趋向还未见报道,本文根据某冶炼企业实际生产情况,统计了2021年及2022年分别为期14d的两套物料平衡数据,对砷、镉、铊在各冶炼工序的分布进行了分析,得到以下结论。砷的分布情况：在底吹炉工序中,约85%砷进入高铅渣,约9%砷进入烟灰,约6%砷进入硫酸净化污酸系统;在还原炉工序,约70%以上砷形成铅铜锍进入粗铅,约20%砷进入还原炉烟灰,10%以下的砷通过还原渣进入烟化炉。镉、铊的分布情况：高度富集于底吹炉和侧吹炉烟灰中,其中底吹炉烟灰中富集比例为85%～95%,只有5%～15%进入高铅渣转至还原炉工序,极少部分进入硫酸系统。企业采用开路底吹炉烟尘方式减少粗铅冶炼系统中砷、镉、铊的含量,开路标准是烟尘含镉超过20%时从收尘系统开路,当烟尘含镉低于15%停止开路,取出的烟尘可直接作为回收镉的原料外售。本文分析结果及解决方法可为同类企业控制冶炼系统中砷镉铊的分布提供参考。

Thallium loading in owls and other birds of prey in Denmark

Due to previous findings of increased concentrations of the rodenticid, thallium, in free-living Danish carnivores, thallium analysis has been carried out on material from 77 owls and birds of prey. Thallium was found in 2/3 of the birds and in 10% the concentration was so high that the load of thallium may have caused the death of the birds. The load of thallium in birds of prey was lower than concentrations found in carnivores, probably because poisoning caused by direct intake of thallium baits placed for rodent control does not seem to occur among birds of prey. From the investigation of this limited number of birds, it is not possible to tell if thallium did have any influence on the maintenance of a healthy population of birds of prey, but the large number of thallium loaded birds also justify the restrictions in the sue of thallium which were given from the 1st of July, 1975.

Serum enzyme abnormalities in protein energy malnutrition

A semi-quantitative right coronary artery score (RCA score) was derived from the ratio of the number of the major left ventricular branches of the right coronary artery to the total of the right coronary and left circumflex arteries, to stratify the extent of perfusion in patients with right coronary artery dominance. Thirty-seven patients with one-vessel coronary disease involving a dominant right coronary artery proximal to the left ventricular branches were selected for study. Thallium scintigraphy was performed after right intracoronary injection in 11 patients, and 26 patients underwent conventional stress thallium scintigraphy (24 exercise thallium and two dipyridamole thallium scintigraphy). Thallium scores of perfusion region size after right intracoronary thallium injection and perfusion defect size in stress thallium studies were quantitated from planar thallium images. Both the RCA score and the regional thallium scores spanned over a wide range. The RCA score (range 0.23-0.85) correlated best with the posterior (70 degrees left anterior oblique view) plus lateral segment (40 degrees left anterior oblique view) thallium score (r = 0.88 and 0.53 for intracoronary and stress thallium studies respectively). It also correlated with the summed thallium scores in the posterior, lateral, apical and inferior segments (r = 0.73 and 0.54 respectively) but not with thallium scores in the apex or inferior segment alone. The proposed RCA score quantitates the variable posterolateral perfusion territory of the right coronary artery, and could stratify the area of myocardium at risk from coronary stenosis in the majority of patients with right coronary dominance.

Aspects of technology transfer

Bibliometric studies have shown that the number of articles and citations of these articles in extractive metallurgy is relatively small compared to most other scientific and engineering disciplines. However, many of these other disciplines can have a significant influence on extractive metallurgy, and this article gives examples drawn from such diverse areas as solid-state chemistry, materials for energy storage, solid-state physics, molten salt chemistry, and physical metallurgy. By use of this information, it is demonstrated that significant improvements in the extraction of metals are possible. The Extraction and Processing Lecturer Award honors an outstanding scientific leader in the field of nonferrous extractive metallurgy with an invitation to present a comprehensive lecture at the TMS Annual Meeting. Derek J. Fray is a Professor of Materials Chemistry in the Department of Materials Science and Metallurgy, University of Cambridge. He earned his B.S. in metallurgy in 1961 and his Ph.D. in extractive metallurgy in 1965, both from Imperial College, London University. Dr. Fray has held teaching positions at the Massachusetts Institute of Technology, the University of Cambridge, and the University of Leeds, where he served as department head. Dr. Fray is the recipient of several honors and awards. He is a fellow of the Royal Academy of Engineering, as well as several other universities and organizations.
