Removal of Metallic Impurities from Off-Grade Copper Concentrate in Alkaline Solution

Removal of Copper from Aqueous Solution by Ion Exchange Resins

Removal of copper ions from aqueous solution by tree fern.

Tree fern, an agricultural by-product, was used for the sorptive removal of copper ions from aqueous solution. The experimental data was analysed by Langmuir, Freundlich and Redlich-Peterson isotherms. The equilibrium sorption capacity of copper ions was determined from the Langmuir equation and found to be 11.7 mg/g. A batch sorption model, based on the assumption of the pseudo-second-order me...

Copper Leaching Behavior from Waste Printed Circuit Board in Ammoniacal Alkaline Solution

A novel energy-saving hydrometallurgical recovery process for copper from electronic scrap employing the Cu(I)-ammine complex has been presented on the basis of a thermodynamic consideration. In order to experimentally explore the feasibility of the leaching stage in this process, the copper leaching behavior from a printed circuit board (PCB) in ammoniacal alkaline solutions has been investiga...
