copper mining sulphide to oxide

This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores Scrubbing sulfur dioxide also protects the environment For example FeOs SiO 2 s→ 2 slag This is very similar to the removal of impurities in the blast furnace The liquid left is a mixture of copper sulfides and iron sulfides
