Review of hydrometallurgical recovery of zinc from industrial wastes
Zinc containing wastes/secondaries viz. zinc ash, dross, flue dusts, sludge, residue etc. are generated in various chemical and metallurgical industries. The materials contain different level ofExpand
Review on hydrometallurgical recovery of rare earth metals
Abstract Rare earth metals are essential ingredients for the development of modern industry as well as designing and developing high technology products used in our daily lives. Consequently, theExpand
Thiosulfate leaching of gold from waste mobile phones.
The present communication deals with the leaching of gold from the printed circuit boards (PCBs) of waste mobile phones using an effective and less hazardous system, i.e., aExpand
Hydrometallurgical recovery/recycling of platinum by the leaching of spent catalysts: A review
Abstract Platinum is one of the precious metals with many applications, including in catalysis, electronic devices and jewelry. However, its limited resources are becoming depleted. To meet theExpand
Solvent extraction of cadmium from sulfate solution with di-(2-ethylhexyl) phosphoric acid diluted in kerosene
Abstract In the present paper, solvent extraction process has been used for extraction of cadmium from sulfate solution using di-(2-ethylhexyl) phosphoric acid (D2EHPA) with 1% isodecanol in keroseneExpand
ABSTRACT Solvent extraction gains importance in the hydrometallurgical processing of ores, and in concentration and even processing of secondaries, due to development of new organic extractants whichExpand
Recovery of lithium and cobalt from waste lithium ion batteries of mobile phone.
