Reclaim the hidden profit in your anode slimes scrap! Specialty Metals is the top choice in the US for secondary refining of Silver, Gold, Platinum, Palladium and Rhodium scrap. Specialty Metals is the top choice in the US for secondary refining of Silver, Gold, Platinum, Palladium and Rhodium scrap.
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.

Water heater anode rods are generally screwed into the top of the tank. In order for the anode rod to work correctly the anode rod must possess a lower, more negative, electrochemical potential than that of the water heater's steel composition to be protected.
Anode slime behaviour in a laboratory‐scale copper electrorefining process. X. Ling. Department of Chemical Engineering, University of Waterloo, Waterloo, Ontario N2L 3G1. Search for more papers by this author. Z. H. Gu.
Anode slime is a byproduct from copper or lead electrorefining process. The copper/lead anode slime usually contain As, Sb, Bi and precious metals like gold and silver.
The anode slime was collected from the electrolytic cells at Sarcheshmeh Copper Complex. XRF spectroscopy was used for mineralogical characterization of the slime, and the results are shown in Table I. The anode slime analysis by the ICP– MS method is shown in Table II. The anode slime contained approximately % copper and % gold.

Anode slime is treated with sulfuric acidic in a furnace within a temperature range of 400–450°C, leached with water, and then filtered. The results show that the dissolution of manganese increases with increasing temperature in the digestion step.
The decopperized anode slime is first leached with nitric acid at an elevated temperature to obtain a leach solution containing at least about 95% by weight of the silver content, 96% by weight of the selenium content and 76% by weight of the tellurium content of the decopperized anode slime.
Anode Plant Blister copper is collected in one of two anode furnaces and when the furnace is full (650 tonnes), the remaining sulfur is removed by injecting air into the molten bath. The oxygen content is then reduced to target levels by injecting a mixture of steam and natural gas.
XRD and MLA were employed to characterize the anode slime. Copper is occurrence in copper sulfide, while stannum is in stannic oxide. ... W.
