Suppression of Cyanide Formation in Hall Process Potlining
EPA Contract Number: 68D00034Title: Suppression of Cyanide Formation in Hall Process Potlining
Investigators: Keller, Rudolf

EPA Contact: Manager, SBIR Program
Phase: I
Project Period: July 1, 1990 through January 1, 1991
Project Amount: $50,000
RFA: Small Business Innovation Research (SBIR) - Phase I (1989)
Research Category: Pollution Prevention/Sustainable Development , SBIR - Pollution Prevention
Description:
Spent potlining from industrial primary aluminum produc- tion cells is a designated hazardous material because of its cyanide content. Over 100,000 tons of this material are annually landfilled in the United States.It would be desirable to avoid the formation of cyanide during the operation of the cells. EMEC Consultants pro- pose to investigate the conditions at which cyanides form and migrate within the cell. It is hoped that ways to eliminate the formation of cyanide can be identified. A possible, proprietary approach is already outlined in the proposal. The experimental investigation of its feasibility is prepared in Phase 1, then planned to actually be initiated on industrial electrolyzers in Phase II.
