10/22/2019 · Extraction of silver from Ag2S by the use of sodium cyanide is an example of : (A) roasting (B) hydrometallurgy (C) electrometallurgy, The development of ion exchange, solvent extraction, and other processes has led to an extremely broad range of applications of hydrometallurgy, now used to produce more than 70 metallic elements. Besides most gold and much silver , large tonnages of copper and zinc are produced by hydrometallurgy.
Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy.
Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Copper can be extracted by this method, but not zinc.
In the hydrometallurgical process of copper anode sludge, valuable metals like gold and silver are extracted as catalysts and antioxidants using sulfuric acid and the presence of ferric ion ( ). In this research, gold leaching will be based on laboratory criterion and copper extraction will be according to laboratory standards and a pilot study ,Kamberovic , et al.
Answer. Hydrometallurgy involves formation of aqueous complex compounds and is used in extraction of less electro positive or less reactive metals like gold and silver. Copper is also comparatively less active metal as its reduction potential is high and it can be displaced from solutions of …
