Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their etallurgy 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 . A Textbook of Hydrometallurgy, 2nd edition The Recovery of Elemental Sulfur from Sulfide Ores by Fathi Habashi Bulletin No. 51 Montana Bureau of Author: Fathi Habashi. The refractory sulfide gold ores in which gold is surrounded by sulfide minerals, oxidative pretreatment of the ore is important to oxidize the sulfides and expose the gold (Carrillo-Pedroza et . As the first book to compile the fundamentals, applications, reference information and analytical tools on the topic, Hydrometallurgy presents a condensed collection of information that can be used to improve the efficiency and effectiveness with which metals are extracted, recovered, manufactured, and utilized in aqueous media in technically viable and reliable, environmentally Cited by:
To make the separation more efficient, small amounts of an anionic sulfur-containing compound, such as Na + C 2 H 5 OCS 2 −, are added; the additive binds to the sulfur-rich surface of the metal sulfide particles and makes the metal sulfide particles even more hydrophobic. The resulting froth is highly enriched in the desired metal sulfide(s. Hydrometallurgy has evolved, both as an alternative to and a complementary method for the pyrometallurgical recovery of metals. It eases the recovery of value metals from ores containing impurities that can produce high-melting-point slags. It also makes it economically viable to recover metals on a smaller scale and from sulfide ores. Hydrometallurgy originated in the 16th century, but its principal development took place in the 20th century, stimulated partly by the desire to extract gold from low-grade ores. 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. Hydrometallurgy. The extraction and recovery of metals from their ores by processes in which aqueous solutions play a predominant role. Two distinct processes are involved in hydrometallurgy: putting the metal values in the ore into solution via the operation known as leaching; and recovering the metal values from solution, usually after a suitable solution .

Example Suppose you are working in the chemistry laboratory of a mining company that has discovered a new source of tungsten ore containing about 5% WS 2 in a granite matrix (granite is a complex aluminosilicate mineral). You have been asked to outline an economical procedure for isolating WS 2 from the ore and then converting it to elemental . hydrometallurgy[¦hīdrō′medəl‚ərjē] (metallurgy) Treatment of metals and metal-containing materials by wet processes.
