Trace Pollutant Emissions from the Processing of Metallic Ores.

摘要

The report gives results of a study of eight metallic ore processing industries. Selected for their potential for hazardous pollutant emissions,the industries were:iron and steel,ferroalloy,primary copper,primary lead,primary zinc,aluminum,titanium,and uranium. Bases for selection were:quantity of ore processed,toxicity of potential emissions,fugitive dust emissions potential,and process characteristics. The report describes the processes in each industry in terms of a functional process statement,process operating conditions,energy requirements,potential emissions,and method of transferring material from one process to the next. Eleven processes are recommended for more detailed study because of their significant hazardous pollutant emissions potential.
