A strategy for the efficient recovery of highly pure copper and antimony metals from electronic waste (e-waste) was implemented by the combination of hydrometallurgical and electrochemical processes. The focus is on copper …
Printed circuit boards, which make up part of waste from electrical and electronic equipment, contain elements that can be economically reused, such as copper, silver, gold, and nickel, as well as metals that are harmful to the environment and health, such as lead, mercury, and cadmium. Thus, through recycling this scrap, materials that would otherwise be discarded …
Different methods e.g. precipitation, solvent extraction (SX) and electrowinning (EW) are available for recovery of copper from leach solutions of WEEE. Copper can be precipitated as hydroxide or sulfide by the addition of sodium hydroxide (or lime) or sulfide salts (Habashi, 1999; Janyasuthiwong et al., 2016). SX can also be used suitably to ...
