The recovery of valuable metals from waste printed circuit boards (WPCBs) is crucial in order to harness their economic resources, and prevents potential environmental contamination. However, selective extraction of Cu and Zn, and the co-extraction of other metals as impurities at ambient temperature using selected lixiviants such as HCl, H2SO4, HNO3, trifluoromethanesulfonic acid …
Mining is the process of digging things out of the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction.Mining can include extraction of metals and minerals, like coal, diamond, gold, silver, platinum, copper, tin and iron.Mining can also include other things like oil and natural gas.. Some mining is done by scraping away the soil (dirt ...
EXTRACTING METALS FROM SULFIDE ORES. Many important metals are present in nature combined with sulfur as metal sulfides; these include cadmium, cobalt, copper, lead, molybdenum, nickel, silver, and zinc. In addition, gold and platinum group metals are associated with sulfidic base metal ores. The extraction of metals from their ores has been an ...
Oct 17, 2020· The copper is refined by electrolysis.The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid.Cathodes are thin rolled sheets of highly pure copper or, more commonly these days, reusable stainless steel starting sheets (as in the IsaKidd process).

Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copper-bearing solution with scrap iron.
