passed to the nickel refinery. There are 21 anodes and 20 cathodes in each cell and a current of 15; amp per square foot is main- tained. The quantity of anode slime formed by the dissolving of these anodes is small and falls to the bottom of the cells, where it is periodically recovered. The dissolving of the nickel anodes
The aim of this research is to get better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of
TBRC is an advanced smelting equipment for treating anode slime, WEEE, non-ferrous metal smelting slag and setting slurry to recover gold, silver, other precious metal and rare metal. It can also treat copper concentrate and secondary material like scrap copper, scrape lead, lead slag, lead dust, etc.
During the electrolysis process pure copper is deposited on cathode plates and impurities which are soluble fall to the bottom of the cell as anode slimes or sludge. Precious metals (Ag, Pt, Pd), can be extracted from the anode sludge created by the electro-refining process. Copper concentrates can also contain precious metals like gold and silver.
The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.

Electrowinning is the oldest industrial electrolytic process. The English chemist Humphry Davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide.. Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in .
the anode slime •With a traditional, moderate temperature autoclave this nickel may not leach in decopperization representing a nickel loss of up to 25% of nickel revenue, lowering the economic return on nickel recovery •Also, that nickel will increase costs in downstream precious metals refinery (PMR)

Nov 23, 2015· This is the third and final installment of our smelting and gold refining series. In this last video we smelt the dried anode slimes and recover a button of precious metals.
A hydrometallurgical process is provided for the recovery of tellurium as elemental tellurium powder from copper refinery anode slime containing high amount of lead. The process involves the removal of copper and lead from anode slime followed by the recovery of tellurium as elemental powders. An economical and environment friendly process is provided for producing tellurium from a high lead ...
Peñoles silver refinery in Torreon, Mexico, operated continuously for three weeks using conditions appropriate to the production of 99.999% gold. The feed to the process was gold-containing anode slime from the silver Gold refining by solvent extraction—the Minataur™ Process by A. Feather*, K.C. Sole*, and L.J. Bryson* Synopsis
Processing of copper anode-slimes for extraction of metal values 127 Forty-gram samples of the decopperised slime were leached with 1 dm3 of solution containing different amounts of acidified thiourea and ferric ion as oxidant.
