  A study on the sulphuric acid leaching of copper converter slag …

  200431 · Abstract In this study, extraction characteristics of Cu, Co, Zn and Fe from copper converter slag by oxidative leaching with potassium dichromate–sulphuric acid lixiviant were investigated. The experimental results indicated that the presence of dichromate has a large influence on the extraction of metals. Cu recovery seems to be …

  Recovery of copper from the copper slag and copper slag flotation ...

  Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings.

  A Review of the Flotation of Copper Minerals

  200921 · An increase in temperature, sulphuric acid and sodium nitrate concentration, and decrease in stirring speed and particle size, enhanced the leaching rate of copper. The experimental data were best fitted by a mixed control kinetic model. An activation energy of 83 kJ/mol was found.

  Pressure leaching of copper converter slag using dilute sulphuric acid ...

  198361 · Abstract In our earlier studies [1–4], conditions were optimized for leaching converter slag with ferric chloride/dilute sulphuric acid for the recovery of cobalt, nickel and copper. By using both leachants most of the copper, nickel …

  Reaction of Copper and concentrated sulphuric acid

  2021414 · The copper takes the [O] and become CuO while sulfuric acid become sulfur dioxide. Then CuO reacts with remaining sulfuric acid to form CuX2SOX4 C u X 2 S O X 4. This is a grossly simplified version of what probably happens, but it gives you a sense of why conc. HX2SOX4 H X 2 S O X 4 can react with Cu. – S R Maiti. Apr 14, 2021 at 9:59.
