Nov 29, 2007· More precisely, the invention relates to a method and device for treating anode slime obtained from copper electrolysis. In copper electrolysis, the insoluble element of the anodes falls on the bottom of the electrolytic tank as anode slime, from where it is recovered when the anodes are replaced.

Luo et al. reported a method for treating anode slime in several operations, including removal of copper and nickel by leaching with dilute sulfuric acid, leaching of selenium, silver and tellurium with dilute HNO 3 (2–8 M), recovery and recycling of HNO 3, selective solvent extraction of silver, and, finally, separation and recovery of ...
Abstract. A vacuum evaporation technology for treating antimonyrich anode slime was developed in this work. Experiments were carried out at temperatures from 873 K to 1073 K and residual gas pressures from 50 Pa to 600 Pa.
Anode slime (product from electrolytic refining of copper cathodes), is one of the most important source for precious metals production. At Aurubis anode slimes are treated in a modern Boliden top blown rotary converter (TBRC) process in two routes and fully controlled by XRF. The LBMA Assaying Refining

TECHNICAL BULLETIN BULLETIN 14 ALUMINUM HYDROXIDE SYMPTOMS "Crackling", "gurgling", or "popping" noises from new water heaters (installed less than six months). CAUSE In a few isolated parts of the United States where the water supply has a relatively high pH (8+), water conditions will react with the aluminum anode to form excessive
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.

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.
The copper anode slime produced in one copper smelter domestically was pretreated with pressure acid leaching method and the leaching behavior of copper,tellurium and selenium in copper anode slime was results show that this method can attain thorough removal of copper and part removal of tellurium and selenium and the silver is still not leached in leaching process.
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 follows the same general pattern, the products 139
