solvent extraction of metals

Solvent extraction for metal and water recovery from Solvent extraction of metals Book WorldCatorg

The use of solvent extraction to recover metals and water from industrial residues is highlighted in this work The method was applied 1 to selectively concentrate Zn from effluents generated by the zinc industry 2 to separate Zn and Fe from spent pickling effluents produced by the hot dip Note Citations are based on reference standards However formatting rules can vary widely between applications and fields of interest or study The specific requirements or preferences of your reviewing publisher classroom teacher institution or organization should be applied
