  • Kinetics of copper leaching from directtoblister copper

    Coppermaking from sulfide concentrates entails two major steps: smelting and converting. In continuous directtocopper smelting process these two steps are combined into one. The principal advantages of this process are: isolation of SO2 emission to a single, continuous, SO2rich gas stream, minimization of energy consumption and Comprehensive Utilization of Copper Slag in a Pyro ,The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. The problem was solved by leaching with sulphuric acid under

    Sulphuric acid is obtained from the sulphur contained in the concentrate treated in the smelting works. The acid has a standard concentration of 98.5%. Sulphuric acid has innumerable applications; it is fundamental in making fertilizers, pigments, acrylic glass, detergent and explosives. It is also vital in electrolysis, fundamentally to refineCopper Smelting and Refining Process Pan ,The matte produced by the flash smelting furnace is transferred to the Converter furnace.

  • IDENTIFICATION OF METALLURGICALSULPHURIC ACID

    Around 200 million metric tons of sulphuric acid is manufactured per year Most of it from strong SO 2 (~12%) gas. SO 2 in smelting and roasting gas accounts for about 30% of sulfuric acid production. Two and a half to four tonnes of sulphuric acid are produced for every tonne of copper smelted from sulphide concentrates [5].Innovations: How Do They Do That? Wringing Sulfuric Acid ,As little as 1%. of the S0 2is emitted, The BHP smelter at San Manuel produces 450,000 gallons of sulfuric acid a day, or enough to fill 12,500 rail cars or 52,000 trucks every year. BHP Copper uses 18 percent of the sulfuric acid it makes for leaching its own oxide ore. Another 40 percent of its sulfuric acid production is sold to other mining
