The Acid Plant is a sulphuric acid and sulphur dioxide production plant to be constructed at KCC, which is anticipated to improve the reliability (compared to imports) of the supply of these reagents to the WOL project processing circuit. The Acid Plant is designed to produce 1,900 tonnes per day of sulphuric acid, 200 tonnes per day of sulphur dioxide and net 17 MW of co-generated power.
The Environmental Protection Agency is investigating the possibility that a high degree of control of sulfur oxides (S02 and SO.,) emissions from copper reverberatory furnace off-gases can be achieved by blending these gases with those from roasters and converters and using the combined streams as a feed to a sulfuric acid plant. The Bor copper smelter in Bor, Yugoslavia, experimented with this

Among the methods of the processing of copper anode-slimes, two of them have been successful on an industrial scale, namely roasting and pressure leaching (Gaylarde and Videla, 1995). The by-production of sulphuric acid is the troublesome aspect of roasting process because the economic marketing of sulphuric acid depends strongly on site location.
Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters
Refined Copper Smelting and Refining Process. After electrostatic precipitators remove dust particles in the gases, the gas is transferred to the sulfuric acid plant. At the sulfuric acid plant, the catalytic reaction of vanadium oxides causes SO 2 to oxidize into SO 3,
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.

Copper Electrolytic Refining Process In the electrolytic refining of copper, a thin sheet of high-purity Cu serves as the cathode. The blister copper plates are taken and used as anodes in an electrolyte bath of copper sulfate, CuSO4, and sulfuric acid H2SO4.
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
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-
Processing of copper anode-slimes for extraction of metal values 129 EFFECT OF ACID CONCENTRATION Figure 5 shows that copper extraction increases when the acid concentration increases from 0.02 M to 0.5 M. A further increase in the acid concentration resulted in practically no increase of copper extraction which may be due to the fact that the

The plant designed was primarily based on the Sulfur based effluents that are currently disposed from the Ceylon Petroleum Corporation refinery at 25 MTPD were to be completely regenerated in the
Copper slag is produced during the smelting process at Hindalco’s copper smelter located at Dahej. Aluminium fluoride: Hindalco produces aluminium fluoride by reacting HFA (a by-product of the phosphoric acid plant) with aluminium hydroxide (from Hindalco’s aluminium manufacturing facilities).
The objectives of the modular copper sulphate production plant concept are: To offer small and medium sized copper oxide concentrate producers an alternative process flow sheet to more conventional dense media separation (DMS) or artisanal hand sorting copper processing methodologies.

Copper blister is pyrometallurgically refined in two 200-ton anode furnaces with further casting in 16-mould casting wheel. Figure 8 gives an overview about the two anode furnaces while figure 9 shows the 3-D modelling.
