  • Copper Mining And Processing Processing Of Copper Ores

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing processing by fire.

  • Manganese Processing Britannica

    The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment.

  • Pdf Pgm Extraction From Oxidized Ores Using Flotation

    A by-product of the smelting and converting furnaces is sulfuric acid. In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW Solvent Extraction 8211 Electrowinning. The acid would have to be made anyway as it would be environmentally unacceptable to release sulfur dioxide gas into the atmosphere.
