Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.
Mineral processing of the ore to generate a commercial iron ore concentrate is very challenging due to the nature of these ores. Accordingly, Hatch and Ironstone are developing a new pyrometallurgical process Hatch Ironstone Chloride Segregation to produce metallic iron from high silica and high phosphorus oolitic iron ores.

The World War II demand for iron and steel stimulated large-scale ore production in East Texas, along with the production of steel. At Longview the Madaras Steel Corporation built a pilot plant in 1941 to reduce iron ore to sponge iron by a process, invented by Julius D. Madaras of Detroit, that eliminated the pig-iron stage and used cracked.
Nov 01, 2016018332Beneficiation. The iron ore sample was initially subjected to classification, jigging, magnetic separation, and flotation techniques for the recovery of the iron values. Magnetic separation studies were conducted by a laboratory model wet high-intensity magnetic separator WHIMS supplied by Box Mag Rapid, England.
Processes in the manufacture of iron ore pellets will be the first sponge iron refining processbeneficiation of raw materials in comminution and magnetic separation, due to the local iron ore raw materials are still many impurities which would lead to lower levels of iron in the material.
Oct 09, 2020018332Sometimes known as direct-reduced iron, sponge iron is a product that is produced using iron ore.The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source. This type of iron can be produced in several different types of furnaces, including coke or charcoal ovens,.
Government may unveil incentives for iron ore beneficiation Indian government has hinted at rolling out more incentives for beneficiation of low grade iron ore in the country. Mr ACR Das industrial advisor to union steel ministry at an industry conference said that quotWe are in the process of drawing up a plan to give some interest subsidy to.
Some iron ore companies are already marketing green iron ore pellets, while others are only just starting to develop beneficiation processes for their production sites. For a high-grade iron ore deposit ie greater than 62 per cent, a dry crushing and sizing process is sufficient to achieve the required product quality and size fraction.
Oct 25, 2013018332NMDC is the prime source of iron ore for sponge iron producers as they have almost 100 reserves of sponge iron grade, particularly DRCLO in Bailadila Sector. They are single largest dominant player in terms of market share of the sponge iron producers. In fact, NMDC has more than 43 of non captive iron ore market share.
