Gaseous dephosphorization is also not suitable because the partial pressure of manganese is higher than that of phosphorus at smelting temperatures. Therefore, the present investigation focused on the development of a suitable flux for selective removal of phosphorus under oxidizing conditions.

The feasibility and technology on dephosphorization from phosphorous iron ores by bio-leaching were investigated.The results show that Acidthiobacillus ferrooxidans(A.f) can remove phosphor from iron ores and nutrient medium without phosphorus is more effective for the removal than that with phosphorus.The addition of pyrite greatly improves the dephosphorization,and the lower initial pH …

Research work on the high phosphorus manganese ores of southern Orissa, however, started at much later period. From 1968 to 1974 extensive investigation was carried out at R.R.L. Bhubaneswar on the chemical method of beneficiation, particularly on the dephosphorization of manganese ores of this region as these ores are also not amenable to beneficiation by any physical method of beneficiation ...

The dephosphorization of manganese ores and concentrates in a reducing atmosphere is thermodynamically analyzed. It is shown that phosphorus can completely pass to a gas phase in a closed reaction system in a wide temperature range (1000–1800°C) at the amounts of a reducing gas (CO) that exceed the stoichiometric minimum required for reduction reactions.

As domestic manganese ores have low manganese and high phosphorus content, they have to be subjected to processing and dephosphorization. One of the most promising manganese ore deposits among proven ones is the Usinskoe mining deposit with the biggest reserves of manganese in Russia. Manganese ores of Usinskoe mining deposit have comparatively low manganese content (18–22%) and high ...

High P manganese ore has complex composition containing several gangue compounds such as SiO 2, Al 2 O 3, MgO, Na 2 O, etc. 10) Because the gangue components of relatively small amount might interact with phosphorus in ores during the formation of manganese iron carbide, the reactions among the major compounds should be studied prior to that of high P manganese ore. Based on the …

In the process of resource utilization of high phosphorus iron ores, phosphorus should be removed first. Compared to other dephosphorization methods, selective leaching with acid has special advantages such as high dephosphorization ratio, low iron loss and so on. However, a large amount of acidic wastewater containing phosphorus was produced after acid leaching.

Dephosphorization of steels has become a very important metallurgical technique in steelmaking process to produce high quality steels. As the P content is controlled by the reactions in BOF, the double slag technique has generally been applied to obtain low P killed steels. However, this technique is accompanied by the increase in operating time and the decrease of the yield of the steel. In ...
