Processing of copper anodeslimes for extraction of metal values 127 Fortygram samples of the decopperised slime were leached with 1 dm3 of solution containing different amounts of acidified thiourea and ferric ion as oxidant.
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. *** Gold recovery ...
Electrolytic refinery slimes are those constituents in the copper anode which remain insoluble during the refining process and ultimately report to the bottom of the electrorefining tank. They are periodically recovered and processed for their metal values.
The chloride leaching solution of lead anode slime is used to recover Cu/ Bi/Sb separately. As a conclusion, it is widely acknowledged that the anode slime is complex in content but of high value, and the tendency to utilize the anode slime is to shorten recovery process and production period, reduce circulating loss and increase recovery rate.
copper anode slime processing equipment made in china Equipments For Attrition For Copper Anode Slime 77 Views. The Zenith is the professional mining equipments manufacturer in the world, located in China,Indiacopper anode slimes processing equipment in .
The equipment may be designed and installed in modules. In this investigation, a sulphuric acid pressure leaching process was proposed among the other hydrometallurgical processes to treat the copperanodic slimes for extraction of copper. The slimes without the copper are then enriched in lead, tin and silver.
transported as LME Agrade copper. The anode slime residue from the electrorefining process is sent to the slimes treatment plant where it is passed through a series of processes to recover gold and silver. Initially, contaminants such as selenium are removed by leaching, before the slimes are neutralised and treated with sodium cyanide to
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 electrorefining process. Copper concentrates can also contain precious metals like gold and silver.
The processing of copper anode slimes is an additional economic driver for copper electrorefineries, due to the fact that slimes contain precious metals such as silver, gold and platinum group metals (PGMs) ( Pt and Pd) as well as base metals like copper, nickel, selenium, tellurium and impurity elements such as lead, antimony and bismuth.
Processing of copper anodeslimes for extraction of metal values. Mar 5, 2002 ... Processing of anodic slimes from an Egyptian copper electrorefining plant, ... Key words: anode slimes, leaching, copper, silver ... capital costs are relatively low when compared to those for a smelter, process may be. Read More
Ag recovery from copper anode slime by acid leaching at atmospheric pressure to synthesize silver nanoparticles. ... An alternative method for processing of copper anode slime is wet chlorination where chlorine solution removes almost all of metals in the anode slime but recovery of silver is poor in this case as AgCl precipitates.
Since anode slime is formed from the insoluble impurities of the anode in the electrolysis process, the composition of the slime depends on the composition of the copper anodes ( Schlesinger et al ...
Selenium is mostly extracted from copper anode slimes because the seleniumrich ores are too rare to be mined with profit. When copper anode slimes are processed in a precious metal plant the first step is to remove copper by pressure leach in an autoclave. The anode slime is .

[Online Chat]
copper anode slimes processing equipment from china. copper anode slime processing equipment from china. How copper is madematerial, used, processing, steps, product . In its nearly pure state, copper is a reddishorange metal known for its high thermal and top two copper producing countries, followed by Russia, Canada, and China. .
The hydrometallurgical processing of copper anode slimes has the advantages such as costs are relatively low when compared to those for a smelter, process may be applied to small and large ...
Anode slimes derived from copper electrowinning contains significant amounts of gold and silver. The processing of the slimes is complicated by the presence of impurities such as Te, Se, Pb, As and Bi. The processes adopted by commercial operations vary widely and are dependent on the initial copper anode slimes composition.
The anode slime is collected in the bottom of the electrolytic cells during the copper electrorefining. This slime generated during the copper refining process contains, among other base metals, costly precious metals. As previously mentioned, the blister copper, from the pyrometallurgical processing of copper sulphides (such as chalcopyrite ...
