ABSTRACT Iron ore tailings have become one kind of the most hazardous solid waste. Beneficiation of iron ore tailings is a significant issue in the world steel industries, from the point of view of both pollution control and secondary resources. This investigation addressed the processing of tailings with high sulphur content from an iron ore concentrator to produce …

The SM ladle treatment processes are comparable for both BF-BOF and EAF steelmaking. However, sulphur removal is less of an issue in the EAF process, since its raw materials (scrap, direct reduced iron) contain less sulphur than the raw materials of the BF-BOF process (iron ore, coke and coal) Citation 1, Citation 4.

Phosphorous is an undesired element present in iron ore used in the steel making process. It leads to an increase in overall production cost as well as deteriorated steel quality. The desired phosphorus content in iron ores used in steel making is < 0.1%. Numerous beneficiation studies are mentioned in the literature; however, there is no commercial scale …

A series of laboratory tests were conducted to investigate the possibility of using sulfur iron ore tailings (SIOT) in GGBS-metakaolin based alkali-activated mortar (AAM) as grouting material. The results indicate that increasing SIOT content leads to a longer setting time of the mortar. This leads to the activation of SIOT particles within the ...

Low-grade manganese oxide ore is generally characterized by high iron content. In this work, sulfidation roasting of an iron-rich manganese oxide ore with elemental sulfur was characterized. The experimental results indicated that manganese dioxide can be selectively reduced over iron oxide by using elemental sulfur.

Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...

In the fourth century BC iron ore started to be mined in the Silesian Upland and the Swietokrzyskie Mountains. At the same time quarries of construction and ceramic materials (stones, clays etc.) appeared in various parts of the country, as did lead, copper, silver and gold mines in Silesia and Malopolska.
