An overview of occupational exposure control technology in nonferrous smelting.
Principles of exposure control include: (1) exposure determination, (2) emission characterization, (3) control options development and analysis, (4) technical and economic feasibility evaluation, and (5) selection, implementation, and testing of the exposure control. New technologies that may reduce exposures are being developed in Europe and the United States. These include new approaches to pyrometallurgical smelting and the development of hydrometallurgical smelting technologies. However, for the time being, retrofit controls will be the primary means of exposure control in the domestic nonferrous smelter industry.
