During Electrorefining Of Copper Gold May Be Recovered From-GOLD MINING


during electrorefining of copper gold may be recovered from

In electro refining of copper, some gold is deposited as: Copper is refined using an electrolytic method. Impurities from the blister copper deposit as anode mud which contains antimony, selenium, tellurium, silver, gold, and platinum recovery of these elements may meet the cost of refining.

during electrorefining of copper gold may be recovered

Black Copper Black is the product of low grade scrap or WEEE/PCB by simple smelting. The composition of black is very compli ed and impurities has to be removed by firerefining in order to get anode possible for further processing by electrorefining to produce standard hode and byproduct anode slime.

Recovery of Gold as ByProduct from the BaseMetals

0183 32 Jan 01, 2016 0183 32Recovery of gold from electronic scrap and other industrial wastes is increasingly practiced. New hydrometallurgical processes have also been developed to recover gold directly from ores or concentrates of copper, nickel, lead, or cobalt these are also briefly described.Cited by: 6

Electrorefining Copper Metallurgist and Mineral Processing

May 24, 2017 0183 32The recovery of precious metals and other metal values from the anode sludge formed during copper refining is a significant part of the economics of copper refining up to 6,000 tons of sludge are recovered and processed each year.11

PDF A study of the influence of copper on the gold

The Journal of The South African Institute of Mining and MetallurgyAPRIL 2004177 . Introduction. Electrowinning is best suited to the partial recovery of gold from solutions with high gold tenors. Furthermore, no foreign ions are introduced into the solution and it can also be efficiently operated at higher temperatures.

Electrorefining an overview ScienceDirect Topics

0183 32 d Recovery during metal refining. During the electrorefining of copper, the small amounts of arsenic, antimony, and bismuth that are present in the blister copper are solubilized and accumulate in the electrolyte. A bleed solution is usually treated by organic solvents to remove or recover these elements.

Which impurities affect metal recovery with electrowinning

Iron as Ferric Fe3 IonChlorideFluoride and BromideOrganic CompoundsSummaryIn the recovery of base metals such as copper, nickel, cobalt, and tin as well as precious metals such as gold and silver, iron can be a major concern and it can be overlooked when considering the process chemistry. In aqueous solutions, oxidized iron species can be present as ferrous Fe2 and/or ferric Fe3 ions. In an electrochemical cell, iron can be problematic owing to the ferrous/ferric redox couple. At the anode, ferrous Fe2 ion is oxidized to ferric Fe3 ion by losing an electron e : Meanwhile, a

PDF Electrorefining of Copper

by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage either via electrorefining from impure anodes or electrowinning from leach or solventextraction liquors. Electrorefining produces the majority of hode copper ca. 95 as: 208KB
