Recovery of valuable metals from electronic and galvanic industrial wastes by leaching and electrowinning

Size-controlled preparation of Cu2O nanoparticles from waste printed circuit boards by supercritical water combined with electrokinetic process

“…Recently, to obtain high purity products of copper from waste PCBs, many new processes were proposed such as leaching-electrowinning [12,13], mechanical separation-electrometallurgy [14], and vacuum metallurgy [15]. In addition, a process combined supercritical water (SCW) and electrokinetic (EK) technique also was developed for the recovery of high purity copper and other heavy metals from waste PCBs [16,17].…”

Equilibrium and Thermodynamic Studies of Pb(II), Cu(II) and Zn(II) Adsorption onto Dicliptera bupleuroides Leaves

“…To protect the public health and environment the removal of these metals from wastewater is important 2 . Copper, zinc and lead have been introduced in the environment from a variety of sources like storage battery 3 , paints and pigments 4 , electronics 5 fertilisers 6,7 and electroplating 8,9 . High concentration of copper leads to severe gastrointestinal irritation and possible necrotic changes in the liver and kidney in human 10 .…”

Preparation of nano-Cu2O/TiO2 photocatalyst from waste printed circuit boards by electrokinetic process

“…Many separation and recycling techniques for Cu in waste PCBs have been developed such as pyrometallurgical [3], hydrometallurgical [4], bioleaching technology [5] and mechanical process [2]. In recent years, to obtain high purity Cu products from waste PCBs, many researchers [6][7][8] proposed some new process such as leaching-electrowinning [6], mechanical-electrometallurgy [7] and vacuum metallurgy technology [8].…”
