Metal Recovery from Leached Plating Sludge
he 23 US. Army installations engaged in plating employ a variety of techniques to treat wastewater. While some sites have implemented recovery and T reuse, a majority still find it advantageous to precipitate the metals and discharge the wastewater. Sludge is collected in clarifiers, treated by gravity thickening, then dewatered in pressure or vacuum filters, lagoons or drying beds. The dewater...
متن کاملrecovery of nickel from spent catalysts by hydrometallurgical method
there are no appreciable amounts of nickel resources in iran; therefore, secondary resources of this element are to be more considered in future. spent nickel catalysts that are used in various industrial processes are one of them. for example nickel catalyst that is used in hydrogenation of edible oil have large amounts of nickel and they are generally supported on porous materials like silica...

متن کاملA Review of Technology of Metal Recovery from Electronic Waste
Electronic waste, or e-waste, is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems, aware‐ ness, and proper regulations, the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal value, including pr...
