Chat Online1. A method of refining iron comprising feeding an iron ore feed a carbon-containing substance and an oxygen containing gas into a secondary reactor to produce products comprising gas and hot solids containing char and partly reduced iron ore separating and removing at least about 90 of the calorific gas from the products produced within the secondary reactor to form an intermediate feed
Chat OnlineThe term "refining" is used in a narrower context. Henry Cort s original puddling process only worked when the raw material was white cast iron rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable a preliminary refining process was developed to remove the silicon.
Chat OnlineThe Ore Extraction and Refining Process Before iron ore can be used in a blast furnace it must be extracted from the ground and partially refined to remove most of the impurities. Leaning on his long tongs this young iron puddler s helper posed for this photograph in the early 1860s when the Sons of Vulcan was a young union.

Chat Online· The cuprous oxide is dissolved in the metal and so carries oxygen to all parts of the molten mass. The process is efficacious but the gold is of course contaminated with the reduced copper. The use of manganese dioxide in the Transvaal in refining gold-zinc-slimes from the cyanide process was described by Johnson and Caldecott in 1902.

Chat Online· When the iron ore is extracted from the mine it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

Coke production is discussed in detail in Section 12.2 of this publication and more information on the handling and transport of materials is found in Chapter 13. 12.5.1.1 Sinter ProductionThe sintering process converts fine-sized raw materials including iron ore coke breeze
Chat OnlineThe principle of zone refining is that the impurities in an ingot or ore of metal are more soluble in the melt state when compared to the corresponding solid state of the impurities. In the zone refining process the impurities are concentrated at one end of the block of metal so that the rest of the block is purified. It can be noted that the
Chat OnlineIron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron one must deoxygenate the ore leaving only iron atoms behind which is the essence of the refining process. To purify and strengthen iron materials like coke are mixed in with it to remove oxygen.
Chat OnlineIron ore coke and lime are added to the top of a furnace. Hot air is blown in from the bottom. The furnace operates at a high temperature (around 1200°C). Iron ore reacts with carbon/coke to form iron metal and carbon dioxide. The iron is tapped off at the bottom of the furnace.
Chat Online· Main component of BF slag is SiO 2 and Al 2 O 3 coming from iron ore as gangue minerals and CaO added as a flux during sintering process. On the other hand BOF slag mainly contains CaO added as a refining agent and SiO 2 and iron oxides produced by oxidation refining process. The EAF slag is classified into two types oxidation slag and
