Figure 1 shows the Fe and gangue contents in the iron ores from different deposits of the major iron ore producing nations and from Muko deposit of Uganda. In this figure, the total gangue content was determined as the sum of SiO 2 and Al 2 O 3 contents in iron ores. All the iron ores were divided into three groups according to the total Fe and gangue content.
Iron ore concentrates are used as a metallurgic raw material in iron smelting with grade between 70 and 72.3% Fe. Iron ore concentrates are characterised by low sulphur and phosphorus content. Iron ore concentrate recovery is based on magnetic beneficiating methods.

Occurrence of high concentration of iron (Fe) in groundwater is very common particularly in areas of tropical climate. In groundwater, Fe generally occurs in the oxidation state - reduced soluble ...
Fig. 1, respectively. The contents of iron total and iron(II) were analyzed by titration method (ISO 25971-1, 2006; ASTM, D 3872, 2005). The XRF analysis (ISO 9516, 1992) was used for the elemental analysis of iron ore concentrate. Table 1. Chemical content of the iron ore concentrate Fe Fe(II) S .

least 65% Fe with reasonable gangue contents (SiO 2 <6.0% and Al 2 O 3 <1.0%). The Davis tube and low intensity drum type wet magnetic separators were used for upgrading the Fe content and separation of gangue impurities from the iron ore. The results showed that, in order to produce a concentrate with sufficient Fe grade (>65% Fe), the iron ...
Iron ore concentrate with Fe content less than 63% A deep beneficiated iron ore product, made from a mixture of dried sintering ore and iron ore concentrate, to be used in blast furnace production. Mixing sintering ore with iron ore concentrate raises the total iron content, which makes sintering and subsequent blast furnace production more efficient.

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...
01-10-2014· In this process, the concentrates were first partially reduced by pulverized coal, with subsequent grinding and magnetic separation to produce iron concentrate and titanium-bearing tailing. The iron concentrate, with a total iron content of 94.57%, could be directly used in steelmaking.
For example, the daily, weekly and monthly indices are listed because of the varied liquidity displayed by different parts of the market. Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references.
IORMs come from iron ore, a rock containing Fe in such quantities that it is advantageous to process the ore. Iron Ore Concentrate. Iron ore concentrate – An enriched product, the content of elements and mineralogical composition of which meet the requirements of further metallurgical processing.
For that reason, hematite ore is important for many mining companies.As Australia's Magnetite Network explains, "[d]irect shipping ores, when mined, typically have iron (Fe) content of between ...

World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil. Production in Australia was 530 Mtonne. South Australian total production in 2013 was in the order of 12 Mtonne, including 3.2 Mtonne of magnetite direct shipping ore, and 665,000 tonne of magnetite concentrate.
01-09-2020· Banded iron ore such as BHQ is one of the potential resources of iron having a total iron content, i.e., Fe (T) of 35–48 wt%, which is lying unutilized in most of the Indian iron ore mines. The challenge before the policymakers and researchers is to think of a sustainable process technology to utilize these iron ore resources wisely.
Figure 1 shows the Fe and gangue contents in the iron ores from different deposits of the major iron ore producing nations and from Muko deposit of Uganda.
