Chapter 82 Metal Processing and Metal Working Industry
The flash smelting process is an example of an energysaving pyrometallurgical process in which iron and sulphur of the ore concentrate are oxidized. The exothermic reaction coupled with a heat recovery system saves a lot of energy for smelting. The high sulphur recovery of the process is also beneficial for environmental protection.
Nucor DRI Facility
to increase its competitive advantage in the industry. One way was to invest in a direct iron ore reduction facility. This process involves converting natural gas and iron ore pellets into highquality DRI (directreduced iron), which is the raw material used by Nucor's steel mills. Not only does this process .
The Blast Furnace | Scool, the revision website
Carbon dioxide produced in 1 + 2 react with more coke to produce carbon monoxide: The carbon monoxide reduces the iron in the ore to give molten iron: The limestone from 2, reacts with the sand to form slag (calcium silicate): Both the slag and iron are drained from the bottom of the furnace. The slag is mainly used to build roads.

Magnetite Facts Figures | The Magnetite Network
The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.

The Properties and Effects of Manganese as an Alloying Element
Effects of Manganese as an Alloying Element. Manganese is used as an alloying element for many different applications. Manganese is a key component of steel. In fact, this chemical element is present in all commercially available steels and is responsible for the steel's hardness and strength, but to less of an extent than carbon.

Amazing Uses of Hematite You Probably Didn't Know About
Usually, any type of iron ore is processed first to get rid of all its impurities before it is fed into the blast furnace for conversion into iron, but because the concentration of iron in hematite is so high, it can be added to the furnace directly without processing it first.
