Mopani Copper Sulphuric Acid

Copper miners using the solvent extraction electro-winning process require between three and 3.5 tons of sulphuric acid to turn ore into one ton of copper metal. Mopani is also seeking to capture at least 97% of the emissions from the smelter before they are released into the atmosphere.

12.3 Primary Copper Smelting

Control of SO2 from smelters is commonly performed in a sulfuric acid plant. Use of a sulfuric acid plant to treat copper smelter effluent gas streams requires that particulate-free gas containing minimum SO2 concentrations, usually of at least 3 percent SO2, be maintained. Table 12.3-

How Hydrometallurgy and the SX/EW Process Made Copper

Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. 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.

Innovations in Copper: Mining & Extraction: Producing

The bacteria, which were native to the soil, in effect created a completely natural metallurgical processing plant. Until recently, conventional acid-leaching of copper was utilized as a means of recovering copper from low-grade materials such as waste rock and flotation tailings and was conducted in dumps that were already in place.

Operations Sterlite Copper (A Unit of Vedanta Limited)

The sulphur dioxide gases generated in the smelting process is collected and ducted to the Sulphuric Acid Plant. Set up with basic engineering from Kvaerner Chemetics, Canada, the plant is based on the absorption process known as DCDA, and has a designed capacity to produce (3600) tonnes of sulphuric acid

Copper recovery using leach/solvent extraction

processes using dilute sulphuric acid. The first process, vat leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of high-grade oxide ores was decreasing and vat leaching was on the decline.

copper processing Definition, History, & Facts Britannica

Copper was discovered and first used during the Neolithic Period, or New Stone Age. Though the exact time of this discovery will probably never be known, it is believed to have been about 8000 bce. Copper is found in the free metallic state in nature; this native copper is the material that humans employed as a substitute for stone.
