EXTRACTION OF COPPER FROM LEACH LIQUOR OF METALLIC COMPONENT IN DISCARDED CELL PHONE BY CYANEX® 272
Discarded cell phones contribute significantly to the amount of electronic waste generation whilst some of its components are toxic and recoverable. Also, due to the increasing demand for Cu(II) in building/construction, electrical and as chemical tool in freshwater, it is imperative to develop low...

| description | Discarded cell phones contribute significantly to the amount of electronic waste generation whilst some of its components are toxic and recoverable. Also, due to the increasing demand for Cu(II) in building/construction, electrical and as chemical tool in freshwater, it is imperative to develop low cost and ecofriendly
technique as a substitute for the conventional treatments such as
reduction-roasting route at elevated temperatures. In the present study, the hydrometallurgical operations involving leaching, solvent extraction and precipitation for the recovery of Cu(II) by Cyanex®
272 in kerosene was examined. Various parameters affecting the extraction of Cu(II) such as pH, extractant concentration and phase ratio were optimized. At optimal conditions, about 96.3 % Cu(II) was extracted into the organic phase by 0.2 mol/L Cyanex®
272 at equilibrium pH 5.0 and aqueous to organic phase ratio 1:1. The stripping of the loaded organic was carried out by 0.1 mol/L HCl solution and stripping efficiency of 98 % was obtained. By McCabe Thiele diagram, four stages are required for complete extraction of Cu(II). |
