Since the late 70’s the use of W reclaimed from scrap has steadily increased. Besides alloying well with nickel, cobalt and iron, and other popular alloying metals, niobium gives the alloy many of its refractory metal properties without adding unduly to the weight. tool steels and nickel-base superalloys Anodes and targets for x-ray. Each cell of a battery stores electrical energy as chemical energy in two electrodes, a reductant (anode) and an oxidant (cathode), separated by an electrolyte that transfers the ionic component of the chemical reaction inside the cell and forces the electronic component outside the battery. The output on discharge is an external electronic current I at a voltage V for a time Δt. The chemical.

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, Co, and Cr from mixed contaminated super­ alloy scrap.

Abstract "The Bureau of Mines is conducting research to recover strategic and critical metals such as ni, CO, and cr from mixed contaminated superalloy scrap. One approach being studied involves melt refining of superalloy scrap to produce anodes for.

Download PDF: Sorry, we are unable to provide the full text but you may find it at the following location(s): (external link) http. The Bureau of Mines investigated a method for increasing the leaching rate of bulk superalloy scrap to facilitate recycling and recovery of critical metals such as Ni, Co and Cr.

The residue from this operation was a nickel–cobalt concentrate. The authors claimed that no solid waste was generated. Hundley and Davwas,Holman and Neumeler, recovered critical metals from superalloy scrap by matte smelting and hydrometallurgical processing.

They present flow diagrams for the recovery of nickel, cobalt, chromium. Holman JL, Neumeler LA () Experimental nickel-cobalt recovery from melt-refined superalloy scrap anodes.

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.

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.

An electrorefining process to recover nickel, cobalt, chromium and other metals from mixed and contaminated superalloy scrap was developed by the U.S.

Bureau of Mines. The process is based on controlled potential electrolysis (CPE) to selectively deposit a nickel-cobalt alloy and permits the recovery of chromium, tungsten and molybdenum as.

The initial experimental results described in this report are from electrolytic tests using alloy anodes cast from elemental nickel, cobalt, and chromium, the main constituent metals of superalloys. Experimental nickel-cobalt recovery from melt-refined superalloy scrap anodes.

Personal Author: One approach being studied involves melt. "The U.S. Bureau of Mines treated mixed and contaminated superalloy scrap by pyrometallurgical and hydrometallurgical methods to separate and recover metal values. Experimental nickel-cobalt recovery from melt-refined superalloy scrap anodes CO, and cr from mixed contaminated superalloy scrap.

Bureau of Mines program to reduce the Nation's reliance on foreign supplies for critical metals, a procedure was devised to separate and recover. "The Bureau of Mines is conducting research to recover strategic and critical metals such as ni, CO, and cr from mixed contaminated superalloy scrap.

One approach being studied involves melt refining of superalloy scrap to produce anodes for electrol.

The products of the process are a chromium-nickel alloy suitable for reuse in the superalloy industry, electrolytic nickel, electrolytic cobalt, and iron-molybdenum residue. Recovery of the principal elements contained in the scrap is chromium percent, nickel percent, cobalt percent, and molybdenum.

The second type of scrap represents the oxidized tantalum and fine-grained unoxidized tantalum scrap. The last one has to be oxidized by roasting, before treating with nitric or hydrochloric acid.

Both types of scrap result in a residue that contains oxidized tantalum (European IPPC Bureau, ). Download: Download full-size image; FIGURE. The anode alloy typically MmNi Co Mn Al (Mm = mischmetal). (NiMH), spent catalysts, and spent/scrap superalloys, and liquid wastes such as copper bleed stream and.L (equivalent to KC20WN), is a single phase cobalt based superalloy, finding extensive applications in liquid propulsion engines.

For optimal performances in service, a uniform fine grained.The recovery of copper and other base metals from secondary copper feeds (including PCB) has traditionally been carried out via remelting and alloying of copper and copper-based alloy scrap (brass.
