How Does Sulfuric Acid Recovery Of Copper

However, it is also applicable in locations where smelter acid is not available by the purchase of sulfuric acid or the manufacture of sulfuric acid from sulfur or pyrite. In addition, it offers the opportunity to recover copper from an entirely different set of ores and mining byproducts than is possible by smelting; namely, oxidized materials.

Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO 4.It is a colorless, odorless, and syrupy liquid that is soluble in water and is synthesized in reactions that are highly exothermic.. Its corrosiveness can be mainly ascribed to its strong acidic nature, …

Sulfuric acid leaching of lead smelter mattes resulted in the recovery of about 45 pct of the nickel and cobalt and 10 to 45 pct of the copper. The addition of manganese dioxide increased the cobalt and nickel recovery from 45 pct to greater than 90 pct, and increased the copper from 10 to 45 pct to nearly 100 pct recovery.

Oct 24, 2019· Copper is less reactive than many metals, but it does react with sulfuric acid. This connection with sulfuric acid has many uses in industry and in learning chemistry. Sulfuric dioxide is produced when copper metal is heated up in concentrated sulfuric acid, and the resulting copper ions can easily react in several other copper related reactions.
