    copper anodesludge:recovery of precious metals, market ...

    In Copper Plants, during electrolysis, pure copper is deposited on the hode plates and impurities which are soluble and fall to the bottom of the cell as anode mud or sludge. Gold, like other precious metals (Ag, Pt, Pd), is extracted from the anode sludge created by the electrorefining process; Copper concentrates often contain precious metals like Au and Ag. Recovery of these metals from ...

    [Recovery of copper from sewage sludge by bioleaching ...

    Sewage sludge contains not only a lot of organic matter and plant nutrients, but also some harmful metals. Recovery of sludgeborn metals for sewage sludge of high metal content is very important for safe reutilization of sewage sludge and for economic consideration. Here, we reported a recovery technique for sludgeborn copper using bioleachingsolvent extractionelectrodeposition (LSXEW ...

    EXPERIMENTAL

    Copper has been plated on steel from complex coppertriethanolamine solutions containing copper oxalate, nitrate, citrate, tartrate and carbo nate which do not deposit copper by immersion. Good quality deposits are obtained over a wide range of operating conditions and the bath performance can be improved by the addition of nitrates, ammonium compounds and rochelle salt. The bath is ...

    The problem of processing slimes of galvanic production, formed as a result of neutralization of technological solutions and wastewater containing heavy nonferrous metals is considered. At present, sludges are transported to disposal area and are not used in any way. Typically, such sludges contain significant amounts of chromium and nickel, which creates environmental hazard.

    The precipitated electrocoagulation sludge is a mixture mainly of copper and aluminum hydroxides, and of some absorbed organic additives present in actual electroplating effluent. The sludge was left to settle down, then was filtered, dried at 102 oC for 24 hours, cooled and weighed. Its quantity follows the Faraday's law of electrolysis and is expressed as mass in g of Total Suspended ...
