Alkylation: In a standard oil refinery process, isobutane is alkylated with low-molecular-weight alkenes (primarily a mixture of propene and butene) in the presence of a strong acid catalyst, either sulfuric acid or hydrofluoric acid.In an oil refinery it is referred to as a sulfuric acid alkylation unit (SAAU) or a hydrofluoric alkylation unit, (HFAU).
The Copper Leaching and Copper Cementation Process The method of dissolution by sulfuric acid and ferric sulfate with chemical precipitation by means of scrap or sponge iron appears to offer the best potential for wide application and low costs.
The aim of including SX in copper refinery plant is removal of copper that bringing with O2 and constructed. In these plants EW is better than SX to removal of copper oxide. The amount of bleeding should be calculated according to amount of O2 in anode.
In a pyrometallurgical process, gas from the gas-cleaning section enters the sulfuric acid plant via a drying tower, where most of the humidity is removed to minimize the potential for corrosion inside the plant.

Sulfuric acid is a corrosive, clear, colorless, odorless, oily liquid that is the largest-volume industrial chemical produced in the world and is the most commonly used strong acid.
The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning plant, with the barred (denuded) sulfuric acid recycled back on …
The first acid plant was commissioned in 2005 with a capacity of 100tpd at Usoke Ave. The sulphuric acid produced at the Usoke compound is used in the leaching of mined ore for the production of copper cathodes and cobalt carbonate.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide ... are used to process such copper-containing materials as intermediate products (e.g., cement copper or ...

Liquid wastes from the copper processing plant include large quantities of water. Most of the water can be reused with minimal refinement. The leaching process creates some sulfuric acid liquid waste.
Espoo/Finland — The contract includes the delivery of three skid mounted, modular sulfuric acid plants that will produce the acid and SO 2 gas required in the process of the new Mutoshi copper-cobalt plant. According to the supplier, the plant concept ensures the benefits of modular prefabricated plant delivery, such as low investment ...

Acid Plant. Processing sulfur technological gases formed in pyro-smelting copper concentrate processing in a smelting furnace and the converters in metallurgical production results in sulfuric acid production. Two systems for sulfuric acid production are used and managed with an automatic system.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
The final phase of the solvent extraction process employs a strong acid to strip the copper from the organic solution, producing a blue, enriched copper-bearing solution that is treated at an electrowinning plant.
Copper processing or pyrometallurgical processes employ high-temperature chemical ... acid plant, which converts the sulfur dioxide-rich gases to sulfuric acid (a useable ... Energy and Environmental Profile of the U.S. Mining Industry. Energy and Environmental Profile of the U.S. Mining Industry Ore . Crushing Grinding Metal. 4. Copper .
The Lurgi-Mitsubishi Double Contact Absorption process is applied in sulfuric acid plant to convert SO 2 in smelter off-gas into sulfuric acid with sulfuric recovery ratio in the world's highest level at more than 99.8%. The sulfuric acid is supplied through pipeline to the next door fertilizer company
This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process. In Latin America, the total is closer to 40% whereas in the United States the total is approaching 30%.
