Nickel Recovery from Western Sources--task 1--Report--technical and Economic Evaluation.
NTIS: PB 256 574 Available for Reference At Bureau Libraries :123 pages
This report describes a conceptual plant design and cost analysis for winning nickel and associated values from Pacific northwest laterite deposits. In the process, selected ore undergoes a controlled reduction with carbon monoxide, a selective oxidation and leaching in ammoniacal ammonium sulfate solution, followed by solvent extraction. The metal values are selectively stripped from the solvents and the metal products electrowon. According to the report, a 5,000-ton-per-day commercial plant based on the process could provide a modest return on equity.
