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
Anode slime is the byproduct of copper or lead electro-refining process and found in electrolytic cell bottom or on the anode scrap surface. The copper anode slime and lead anode slime usually contain precious metals like gold and silver. Depending on the treatment capacity, process of anode slime recovery is achieved by two different methods ...

Anode slime is an important material of recycling precious metals. Up to now, treating the arsenic- and antimony-rich anode slime by conventional processes has the following problems: its economic and environmental effect is less than satisfactory, and the removal effect of arsenic and antimony from anode slime in present processes is not all that could be desired.

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 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 being pure nickel cathodes and an anode slime containing the .
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
