Pig iron is an intermediate product of the iron industry also known as crude iron which is obtained by smelting iron ore in a blast furnace Pig iron has a very high carbon content typically 3 8–4 7% along with silica and other constituents of dross which makes it very brittle and not useful directly as a material except for limited
Iron ore is converted into various types of iron through several processes The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements Pig iron has only limited uses and most of this iron goes on to a steel mill where it is converted into various
Requirements/Products The overview tab of the industry window shows which cargo items are consumed and produced The | symbol stands for "or" so the requirements in the example on the right are two planks or one steel to produce one tool In addition the factory will use two planks and one steel or one steel and one plastic to produce a machine

Beneficiation of Iron Ore and the treatment of magnetic iron taconites stage grinding and wet magnetic separation is standard practice This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation All such plants are large tonnage operations treating up to 50 000 tons per day and ultimately requiring grinding as fine as minus 500
The iron ore production has significantly expanded in recent years owing to increasing steel demands in developing countries However the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter shows the status of the pelletizing process
Dewatering is an important process in mineral processing The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density This is done for a number of reasons specifically to enable ore handling and concentrates to be transported easily allow further processing to occur and to dispose of the gangue

Learn everything you need to know about zinc mining and processing including what zinc is used for and where it is found The zinc mining process is conducted primarily underground with more than 80 percent of all zinc extracted beneath the Earth's surface Eight percent of zinc is mined in open pits with the remaining 12 percent being
The more advanced way to smelt iron is in a blast furnace A blast furnace is charged with iron ore charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ) Huge quantities of air blast in at the bottom of the furnace and the calcium in the limestone combines with the silicates to form slag
Jul 20 2017A mixture or burden of iron ore limestone flux and coal is heated in a blast furnace to produce molten iron or pig iron from which steel is made Emerging ironmaking processes such as smelting reduction and direct iron plants are not as widely used but their adoption is expanding as the technology improves and environmental concerns grow
