Selective extraction, separation and recovery of Cu(II) in presence of Zn(II) and Ni(II) from leach liquor of waste printed circuit board using microcapsules coated with Cyanex 272
(Springer Verlag, 2012-05)
The study was conducted to optimize the selective extraction and recovery of Cu(II) in the presence of Zn(II) and Ni(II) from the leach liquor of waste printed circuit boards (PCBs). The extraction experiments were carried ...
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 ...
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 ...
