Extraction of iron from copper-plant slag | SpringerLink

In the production of copper from sulfide ore slag accumulates at the processing plant. In the present work the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag may be converted to metallic form by the gasification products of carbon in .

Innovations in Copper: Mining & Extraction: Producing copper .

Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal) the only way to recover copper from an acid solution was by a process called cementation. In this process copper was in effect "traded" for iron by contacting the copper-bearing solution with scrap iron.

and 5-61 ppm magnesium. Traces of copper ranged from 4 ppm in iron tailings to 570 ppm in copper tailings. Iron content varied from 137 ppm in copper tailings to 1248 ppm in iron tailings. Particle size separates ranged from fine sand to clay. The tailings are structureless with no consistency and are easily eroded by wind and water.

Iron Extraction and Purification / Steel | ChemKey

Avoiding the pollution problems in the extraction of iron from the ore. Not having to find space to dump the unwanted iron if it wasn't recycled. (Offsetting these to a minor extent) Energy and pollution costs in collecting and transporting the recycled iron to the steel works.

Innovations: Introduction to Copper: Mining & Extraction

The process yields concentrates containing roughly 30% copper which are sequentially fed to a smelter a furnace in which most of the some iron and sulfur are removed then to a converter or converting furnace where most of the remaining iron and other impurities are removed. (Depending on the type of smelting and converting furnace used as .

Where such ore is mined at a cost of between 25c. and 50c. a ton it is commercial on a 12c. market even if leached with sulphuric acid and the copper precipitated with pig iron to the waste of the acid and iron and the production of an impure cement copper that requires further treatment.

Copper leaching from primary sulfides: Options for biological .

In addition to the reactions involving the copper minerals pyrite in the ore will also oxidize to a limited extent (2–3%). This minor oxidation is beneficial in regenerating soluble iron and acid for the leach system. The leached copper sulfate is forwarded to solvent extraction and electrowinning of copper cathode.

Iron processing | Britannica

History. There is evidence that meteorites were used as a source of iron before 3000 bc but extraction of the metal from ores dates from about 2000 bc.Production seems to have started in the copper-producing regions of Anatolia and Persia where the use of iron compounds as fluxes to assist in melting may have accidentally caused metallic iron to accumulate on the bottoms of copper smelting .
