Sep 01, 2010 To eliminate such risks, China has to focus on the utilization of its domestic iron ore resources though most of them are either refractory or of low gradeC-23, A large deposit of over 4 billion ton of high phosphorus iron ore is in Hubei province with an Jul 31, 2021 Abstract. High-phosphorus iron ore resource is recognized as refractory iron ore because of its high phosphorus content and complex ore phase structure. Therefore, it
High-phosphorus iron ore is traditionally dephosphorized by chemical process with inorganic acids. However, this process is not recommended nowadays because of its high cost and consequent environmental pollution. With the current tendency for development of a low-cost and eco-friendly process, deph Sep 01, 2010 A new method (gas-based separation plus melt separation) has been proposed to remove phosphorus of the high phosphorus iron ore which was 1.25% of phosphorus content and 50.0% of iron content. HSC chemistry package and the coexistence theory of slag structure were adopted for theoretical analysis. The gas-based reduction was carried out using a fixed bed reactor and the ore

Many countries have high phosphorous iron ores distributed with some large scale deposits worldwide such as Sweden, France, Canada, Pakistan, China, northern Sudan, Nigeria and Italy . It was found that several possible ways to 8 make high quality steel from high phosphorus apatitic iron ores, of Soc China, v. 22, p. 28062812, 2012. investigated the phosphorus removal of oolitic hematite ore of high content of iron by applying a reductive calcination with dephosphorizing agent (Na 2 SO 4 and Na 2 CO 3). The calcined mass was subjected to two stages of magnetic separation and grinding.

Dec 08, 2021 Chinas iron ore imports hit 13-month high in November. China imported about 105 million tonnes of iron ore in November 2021, up by 7% year on year and 15% higher than in October, according to the latest Chinese customs data. The last time import volumes were at this level was October 2020. From January to November 2021, China imported 1 billion tons of iron ore, down by 2.1. Iron Ore Sample Analysis. The high phosphorus oolitic iron ore used in this research was obtained from western Hubei in China. Table 1 shows the chemical composition of the ore examined by chemical analysis, indicating that iron content reached 51%, and phosphorus content was 0.52%. If phosphorus could be removed appropriately, the ores of this kind would be of great value in use.
