copper extraction blast furnace


Useful Products from Rocks - Chemistry GCSE Revision

Extraction of Iron Ore from a Blast Furnace. A metal such as iron which is less reactive than carbon can be extracted from its ore using carbon. Reactions in the blast furnace: C O 2 > CO 2; The coke burns to form carbon dioxide and to produce heat; CO 2 C > 2CO; The carbon dioxide reacts with more hot coke to produce carbon monoxide gas.

Reinventing copper extraction with electricity MIT News

Reinventing copper extraction with electricity Greater recycling of steel which uses electric arc furnaces instead of coal-fired blast furnaces has also fueled the improvements in energy consumption. & 34;If you look carefully at the history of aluminum production steel production which are commodities where we speak about little numbers

copper extraction and purifi ion - chemguide

Extracting copper from its ores. Much like in the Blast Furnace the calcium carbonate is involved in the production of the slag. An overall equation for this series of steps is: The copper I sulphide produced is converted to copper with a final blast of air. Warning

Copper Blast Furnace Smelting-Copper-

Copper Blast Furnace Smelting Blast furnace has been used for iron/copper/copper-nickel/zinc/lead and zinc-lead complex concentrate smelting for a long time. It plays a fundamental role to modern metallurgy and is still very important in the small-scale smelting appli ion.

Copper extraction - Wikipedia

Smelting was initially undertaken using sinter plants and blast furnaces or with roasters and reverberatory furnaces. Roasting and reverberatory furnace smelting dominated primary copper production until the 1960s.

Extraction of Copper from Copper pyrite Grade 12 Science

In molten state FeS and Cu2S are missible and the molten mixture of Cu2S and FeS is called copper malte. The lower end of blast furnace has two openings for slag and copper matte. Fig: Blast Furnace for extraction of copper


EXTRACTION OF COPPER IMPORTANT ORES OF COPPER Copper pyrite or chalcopyrite CuFeS 2 . Chalocite Cu 2 oThe concentrated ore is then roasted in a furnace between 500oC and 700 C in the presence of a current of air. Sulphur is oxidized to SO blast furnace with 1200oC. The hot air is blasted and FeO is converted in to ferrous
