PdCl4 þ 2H2 O ðDG0 ð75 CÞ Fig. 5. A process flowsheet proposed for hydrometallurgical extraction of copper and precious metals (Au, Ag and Pd) from PCBs of scrap mobile phones (Quinet et al., 2005).
Because copper is an element, it can be infinitely recycled. New and old copper scrap or copper alloys can be melted, repurified, and recycled into new components ~50% of copper used in the copper industry was recycled. In 2010, 770,000 metric tons of copper were recycled, at estimated value of 6 billion
The development of copper hydrometallurgy is presented and various processes proposed for copper recovery from sulphide concentrates are discussed. Leaching, extraction and stripping are considered, including reagents and processes. The extraction of copper from chloride solutions is discussed.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and ...
The resulted powder was leached with HNO 3, and then the solution was submitted to solvent extraction with di(2ethylhexyl) phosphoric acid (DEHPA) using nheptane as a diluent. For reextraction, HNO 3 was used again, and yttrium was precipitated by adding four times the stoichiometric amount of oxalic acid, reaching 68% yttrium purity.
Hydrometallurgy, which involves the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual material, plays an integral role in the multibillion dollar minerals processing industry.
Sep 09, 2019· The used approach utilizes thermodynamic relationships coupled with original mass balance constraints, where the solid phases are explicitly expressed. The obtained results are useful for optimization of the overall scheme of thiosulfate leaching in gold hydrometallurgy to minimize reagent consumption and maximize gold extraction.

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copperinconcentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically .
