removing of sulphur and iron from copper ore

Copper Mining and Extraction Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air. The product from ...

Copper extraction - Wikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates ...

This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year. The pale green liquid draining from the bottom contains ...

The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur ...

This stage changes Copper Iron Sulphate (CuFeS2) to copper oxide (CO). It removes some sulphur as sulphur dioxide. By heating the concentrated ore between 500°C and 700°C in air, the product is calcine, a solid mixture of oxides, sulphides, and sulphates. This is one reaction which takes place to purify the copper: 2CuFeS2(s) + 3O2(g) > 2FeO(s) + 2CuS(s) + 2SO2(g) Smelting with fluxes ...

smelting Definition Facts Britannica

In modern copper smelting, a reverberatory furnace is used. Concentrated ore and a flux, commonly limestone, are charged into the top, and molten matte—a compound of copper, iron, and sulfur—and slag are drawn out at the bottom. A second heat treatment, in another (converter) furnace, is necessary to remove the iron from the matte.

The matte (copper-iron sulfide) from the furnace is charged to converters where the molten material is oxidized in the presence of air to remove the iron and sulfur impurities (as converter slag) and to form blister copper. Blister copper is further refined as either fire- refined copper or anode copper (99.5% pure copper), which is used in subsequent electrolytic refining. In fire-refining ...
