There is a great variety of manufacturing and industrial wastes with significant contents of chromium and nickel. Among them are stainless steel and ferroalloy flue dusts, electrochemical and electrical discharge machining sludges, spent electroplating solutions, and sludges. Although chromium and nickel are both scarce and costly, neither metal is reclaimed from these nuisance wastes. The present report views the technology presently available for recovering cr and ni from metalliferous wastes, much of it developed in federal Bureau of Mines laboratories. The status of the most promising recovery schemes is described with recommendations as to which would benefit from pilot plant or industrial trials.
