Manufacture of Steel

  The first step in the steel manufacture begins at the blast furnace To separate iron from iron ore coke substance when gas is taken out of coal limestone and dolomite are charged into the blast furnace Temperature raised to 1600oF This high temp causes the coke to burn and melt the iron This red hot iron drained at an opening at the base of the furnace.

iron processing

iron processingiron processingIron making The primary objective of iron making is to release iron from chemical combination with oxygen and since the blast furnace is much the most efficient process it receives the most attention here Alternative methods known as direct reduction are used in over a score of countries but less than 5 percent of iron is made this way.

Melting stages The overall duration of the process can be divided into three main stages 11 Heating stage The scrap is heated by the arc and oxy fuel burners at the top of the furnace The heating is done by radiation convection due to the hot gas going through the scrap porosities and conduction due to contact points between scraps.

Copper recovery using leach/solvent extraction

 

low quality copper from the leach solution on scrap iron was practiced on oxide ore that was too low grade for vat leaching or low grade sulphide ore that had to be mined in order to expose the underlying high grade sulfide ore Copper recovered from leaching low grade copper ores was considered a bonus and little effort had been made to fully understand the leaching process or to maximize

Sintering A Step Between Mining Iron Ore and Steelmaking

  Seven open pit iron ore mines each with associated concentration and pelletizing plants and three iron metallic plants one direct reduced iron DRI plant and two hot briquetted iron HBI plants operated during the year to supply steelmaking raw materials The United States was estimated to have produced and consumed of the world s iron ore output. Globally iron ore

Extracting ores

We will discuss the extraction of iron from iron ore as an example Extraction of iron Iron atoms are found in the compounds FeO Fe 2 O 3 and Fe 3 O 4 and in rocks like haematite and magnetite South Africa is the seventh largest producer of iron ore in the world Iron has been mined in South Africa for thousands of years South African

Steelmaking CO2 carbon dioxide emissions by process step

The main process steps that generate carbon dioxide in iron and steelmaking are the production of coke and the production of hot metal in the blast furnace Ancillary facilities such as power plants also produce large volume of CO2 The table below identifies typical CO2 production volumes per tonne of output for each steelmaking process stage Figures show are for typical steel plants in the
