The Blast Furnace
The Process . Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from to inches. This ore is either Hematite (Fe 2 O 3) or Magnetite (Fe 3 O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any .

is operating with an air blast than if it is operating with an oxygen blast. While the smelting process is continuous, tapping of matte and slag are intermittent. Matte is tapped into ladles for transport to converters, and slag is either tapped into a cleaning furnace for copper recovery or is dried and recycled into the flash furnace with ore concentrate. 3. 11. b. 12. background report. 3 ...
Blast Furnace Process
· Important properties of sinter for blast furnace process are reducibility, size and size distribution, cold and hot strength, and softening and melting behavior. Typical sinter suitable for blast furnace process is from 15 to 25 mm, as is illustrated in Figure [22].Another important property is the disintegration of sinter in reduction, which occurs during the transformation of .
Secondary Lead Processing
Refining furnaces are used to either remove copper and antimony for soft lead production, or to remove arsenic, copper, and nickel for hard lead production. Sulfur may be added to the molten lead bath to remove copper. Copper sulfide skimmed off as dross may subsequently be processed in a blast furnace to recover residual lead. Aluminum chloride flux may be used to remove copper.

How it is Done a picture of open pit mine blasting There are two types of copper ore sulphide ore and oxide ore and each is treated .
ISASMELT
The process used at the Lünen smelter involves charging the furnace with copper residues and scrap containing between 1 and 80% copper and then melting it in a reducing environment. This produces a "black copper phase" and a lowcopper silica slag. Initially the black copper was converted to blister copper in the ISASMELT furnace.

Fig: Blast Furnace for extraction of copper. Bassemerisation The molten matte is mixed with little silica and charged into a Bessemer converter. Lined internally by basic lining of CaO or MgO. Hot air is blown into the mixture which converts remaining FeS. To FeSiO 3. 2FeS + 3O 2 → 2FeO + 2SO 2 FeO + SiO 2 → FeSiO 3 (slag) The slag is removed and air is passed. The air oxidized Cu 2 S ...
Primary Metal Production
These are vertical furnaces with the charge added at the top and removed at the bottom, while gas is blown into the bottom and exits the top, as shown in Figure 1. The solid charge must consist of particles coarse enough that they will not be blown out of the furnace by the gas. An iron ore blast furnace is a typical example of a shaft furnace.

how is copper processed
Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of % purity. Copper can be recycled indefinitely without the base metal .
