Abstract
This chapter basically covers solder strip leaching, base metal leaching, and precious metal leaching techniques. Previously performed laboratory and industrial leach test results, conditions, reagents, extraction ratios, leach reactions, and flowsheets are reviewed and discussed in detail. Alternative leaching reagents are compared from chemistry, research level, and commercial extend points of view. Analytic hierarchy process (AHP) is used to compare various leaching processes. Brominated epoxy resin leaching, purification of metals from leachates by solvent extraction, and industrial scale refining solutions are also covered in this chapter. Occupational, health, and safety hazardous characteristics determination tests were briefly mentioned.
