مصنع لتجهيز البوكسيت/Iron Making From Magnetic Slag
This work presents a semismelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore. The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized. The results show that the iron nuggets and alumina slag can be ...
An integrated steel plant generates 200250 kg of steel making slag for every tonne of steel produced. These slags contain nonuniformly distributed iron in metallic form, inevitably carried into the slag pot during deslagging. The steel slag is subjected to crushing/magnetic separation to generate different sizes of slag products with varying metallic values.
10/10/2017 · Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.

This slag may find appliion in refining of steel or iron making processes due to its high metal value and lime content provided phosphorus (P2O5=24 %) is removed from the slag.
04/06/2020 · A novel technology, modified roasting in CO–CO 2 mixed gas and magnetic separation, was presented to recover iron from copper slag. The effects of various parameters such as dosage of flux (CaO), gas flowrate of CO and CO 2, roasting temperature, roasting time, particle size of modified slag and magnetic flux density on the oxidized modifiion and magnetic separation were .
Crushing and Magnetic Separation Steelmaking slag includes 10% to 40 % iron metal which can be separated for different purposes. Iron can be recovered and used as a substitute for scrap iron, iron can be segregated for effective use of slag for appliions where iron would act as an impurity. For these reasons the slag is crushed and iron ...

28/07/2016 · Steelmaking slags are usually processed for iron recovery by dry magnetic separation. The recovered ironrich products are recycled back into the ironmaking and steelmaking processes to replace highcost steel scrap and iron ores. However, current slag processing is far away from optimum conditions, especially for slag fines with small particle sizes, resulting in generation of nonrecyclable ...

The present invention provides a method of separating and recovering iron from a waste nonferrous slag, generated in a process for smelting of nonferrous metals, including copper, zinc and lead, in which a reducing agent and a reaction alyst are added to the crushed waste nonferrous slag, and the mixture is subjected to a reduction reaction, thereby converting amorphous iron oxides ...
01/01/2019 · 01/01/2019 · The steel slag is subjected to crushing/magnetic separation to generate different sizes of slag products with varying metallic values. Based on size and metallic content, these products are recycled in sinter base mix, iron making units and as scrap in steel making process.
29/10/2019 · Slag is the byproduct of iron and steelmaking processes. Normally, around half to one tonne of slag would be generated for yielding one tonne of rolled iron or steel (Lobato et al. 2015).It was reported that the world steel production was billion tonnes in 2016, which suggested that at least around 1 billion tonnes of slag is produced during the year (Worldsteel Association 2016).
25/05/2017 · The magnetic iron in the copper slag gradually transformed to fayalite, and the viscosity of the copper molten slag decreased as the magnetic iron content decreased during the reduction process.
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...
01/04/2003 · In Denmark iron production, by means of reducing bog‐iron ore with charcoal, was carried out at least between the second and seventh century AD.
