    used to produce a matte 40 50 wt Cu and a disposal slag ca. 0.5 wt Cu. In contrast, oxide ores are processed directly to impure black copper 95 wt Cu and to a copper-rich slag. The two ore types can be smelted together to produce matte and a slag with low copper content. Another product is top gas, which contains flue dust..This concentrated ore is mixed with limestone CaCO 3 and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag..Nov 07, 2007 Titanium Dioxide TiO2 Production and Manufacturing Process. TiO2 is produced from either ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid sulphate process or chlorine chloride route. The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores.

    Development of Manufacturing Process for Blast

    Blast furnace slag is a combination of silica and other non-ferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered..process for metallurgical dusts and ore nes recycling as presented to the ow sheet in the corresponded supplementary le. Examined parameters were slag FeO x.10.2.2 Blast furnace slag. Blast furnace slag BFS is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is
