EXPERIMENTAL NICKELCOBALT RECOVERY FROM MELTREFINED SUPERALLOY SCRAP ANODES By J. Holman1 and L. Neumeier2 ABSTRACT The Bureau of Mines is conducting research to recover strategic and critical metals such as Ni. Experimental nickel-cobalt recovery from melt-refined superalloy scrap anodes.

Pittsburgh, Pa.: U.S. Dept. of the Interior, Bureau of Mines, (OCoLC) @article{osti_, title = {Experimental nickel-cobalt recovery from melt-refined superalloy scrap anodes. Report of investigations/}, author = {Holman, J L and Neumeier, L A}, abstractNote = {The Bureau of Mines is conducting research to recover strategic and critical metals such as Ni, Co, and Cr from mixed contaminated superalloy scrap.

We are developing improved technology to increase the recycling of mixed contaminated Cr-Co-Ni-bearing scrap and waste materials. According to a study of critical metals availability approximately million lb/yr of mixed contaminated superalloy and associated heat- and corrosion-resistant high-alloy scrap is downgraded or exported.

The scrap is melt-refined and cast into anodes for electrodeposition of recyclable Ni-Co alloy. Experimental nickel-cobalt recovery from melt-refined superalloy scrap anodes. Published Date: One approach being studied involves melt refining of superalloy scrap to produce anodes for electrolytic deposition of ni-co alloy.

This melt refining of superalloy turnings is described based on melt-oxidation and oxidation-carburization. Experimental nickel-cobalt recovery from melt-refined superalloy scrap anodes / ([Pittsburgh, Pa.]: U.S.

Dept. of the Interior, Bureau of Mines, []), by J. Holman and L. Neumeier (page images at HathiTrust) The Nickel question [electronic resource]: shall nickel matte be subjected to an export duty.

One approach being studied involves melt refining of superalloy scrap to produce anodes for electrolytic deposition of Ni-Co alloy. This melt refining of superalloy turnings is described based on melt-oxidation and oxidation-carburization experiments, using roasted superalloy grinding sludge to supply the 0 needed to oxidize Cr and other.

Furthermore, such waste products have accumulated in huge quantities and call for serious action for resource recovery and environmental reclamation. Resource recovery from such 'waste' or converting them to useful by-products is a growing necessity as discussed in Section student resource book.
