Selective leaching for the recovery of Copper from PCB
(Universiti Malaysia Perlis, 2009-12-01)
This paper reported on the leaching behavior of printed circuit board (PCB) using a new leaching agent of ammonia-ammonium persulfate, to recover copper. Cu and Zn leaching were found to be fast and reached equilibrium in ...
Extraction and separation of Cu(II), Ni(II) and Zn(II) by sol-gel silica immobilized with Cyanex 272
(Elsevier B.V., 2009-03)
The extraction and separation of Cu(II), Ni(II) and Zn(II) from aqueous sulfate-acetate solution were carried out using solid phase sol-gel silica containing immobilized Cyanex 272 {bis(2,4,4-trimethylpentyl)phosphinic ...
A study on floatability of copper using modified hallimond tube
(Universiti Malaysia Pahang, 2009-06-20)
The Floatability of copper on the
Modified Hallimond tube depend on lots of
parameters such as dosage and types of collector,
frother, air flow rate, flotation time, and pH value.
All of this parameters give different ...

Electrical properties and thermal stability of Cu-P containing electrically conductive adhesives
(Universiti Malaysia Perlis, 2009-12-01)
Electrically conductive adhesives (ECA) containing Cu-P and Cu as metallic filler, respectively, were studied in term of electrical properties and thermal stability. Both metallic fillers used in this study were prepared ...
Studies on mechanical alloying of copper-tungsten carbide composite for spot welding electrode
(Springer New York, 2009-12)
This article presents a study on the properties and performance of copper-based composite reinforced with recycled tungsten carbide powder as spot welding electrode. The copper-tungsten carbide composite electrode was ...
