electrolytic refining

Electrolytic refining had the advantage that it separated out the silver from the copper.

Anodes are shipped to an external copper refinery for electrolytic refining.

In 1920, he patented a refining process that became the basis for recovering nickel by electrolytic refining.

In electrolytic refining, fire-refined copper is cast in the form of a large block, which acts as an anode.

The major stages in the pyrometallurgical route are smelting, converting, refining and electrolytic refining.

These cannot be removed by fire refining and the copper must undergo an additional refining process, electrolytic refining.

Unrefined copper; copper anodes for electrolytic refining.

The principal source of tellurium is from anode sludges produced during the electrolytic refining of blister copper.

Soon after, in the 1870s, Electrolytic refining of gold was developed, the Wohlwill process, to deal with the problem of removing platinum from the gold.

Copper Cathodes are the product of electrowinning, direct from leach solutions or following solvent extraction, or of electrolytic refining.

'It is entirely of Australian manufacture produced by The Electrolytic Refining And Smelting Co.

• Earliest attempt for electrolytic refining of nickel, Hoepfner Refining Company, Hamilton, Ontario (closed 1902).

These pyrometallurgical operations include successive stages of roasting, smelting, converting, and electrolytic refining in specialized furnace processes to remove sulphur and other metallic impurities.

CATHODE - A rectangular plate of metal produced by electrolytic refining which is melted into commercial shapes such as ingots.

Correspondence with the Electrolytic Refining & Smelting Co. of Australia re supply and treatment of Mt Morgan blister copper.

The Butte system, while sound, deliberately replaced to lower the load on the overtaxed electric system, which was primarily used for commercial uses, including electrolytic refining of copper and zinc.

The ATSDR also notes how the electrolytic refining process also required the management of large amounts of acidic waste capable of dissolving heavy metals:

The product is then cast into copper anodes which are shipped to Noranda Metallurgy Inc.'s CCR Division in Montréal-East for electrolytic refining.

Silver is also produced during the electrolytic refining of copper and by application of the Parkes process on lead metal obtained from lead ores that contain small amounts of silver.

At the end of the 19th century, a chemist at the refinery perfected the electrolytic refining of copper, a process that produced a purer form of copper needed in electrical wiring.

Electrolytic refining of copper was first patented in England by James Elkington in 1865 and the first electrolytic copper refinery was built in Newark, New Jersey, in 1883.

For example, anode casting - the conversion of blister Cu (the impure product of the smelting process) into anodes for use in electrolytic refining - may take place at either a smelter or a refinery.

Finally, anodes (in what is known as tough pitch copper) for electrolytic refining are produced in a furnace in which sulphur is burned off with air blown through tuyeres, after which excess oxygen is removed.
