Selective Extraction of Metals from Chloride Solutions 2019-5-24  Rare earths are not extracted at low pH values, whereas some transition metals (Fe, Mn, Co, Zn, Cu, In) are extracted. This makes [P8888][oleate] a promising extractant for the separation of transition metals from rare earths. It is also shown that this bulky and long-chained IL has a very low viscosity due to the uptake of water. Recovery of metals and nonmetals from electronic The recovery of metals from e-waste material after physical separation through pyrometallurgical, hydrometallurgical or biohydrometallurgical routes is also discussed along with purification and refining. Suitable PCB recycling flowsheets for industrial applications are also given.
