Jun 24, 2015· Distribution behavior of phosphorus and metallization of iron ore in the carbothermic reduction of high-phosphorus iron ore were investigated. Reduction degree of the iron oxide was evaluated by quadruple mass spectrometry connected to thermogravimetric analysis.
Alkali-leaching and acid-leaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12% for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions.
Bog ore often has a high phosphorus content (Gordon 1996, p. 57). The strength and hardness of iron increases with the concentration of phosphorus. 0.05% phosphorus in wrought iron makes it as hard as medium carbon steel. High phosphorus iron can also be hardened by cold hammering. The hardening effect is true for any concentration of phosphorus.
Jul 01, 2016· Ultimately, the aim is two-fold: firstly, to produce iron ore concentrates with market specifications, based on a biodesphosphorization process for high-phosphorus iron ore deposits that exist across Europe and worldwide, and secondly, to improve the economic competitiveness of marginal iron ore deposits by value-adding by-products and waste.

Ihigh phosphorus iron ore beneficiation in china. Beneficiation iron china Iron ore beneficiation plant, iron ore crushing and Iron ore beneficiation equipment zenith is a iron ore machine manufacturer in China, Chat Mechanism of phosphorus removal in beneficiation of high Abstract: High phosphorous oolitic hematite ore is one of typical intractable iron ores in China, and the.
Iron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite. Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid (Xia et al., 2011).
The conventional beneficiation process of iron ore is found to be less effective in phosphorus removal of high phosphorus oolitic hematite, which is one of the most refractory ores in China. One ninth of China's iron ore resources are oolitic hematite, in which 30−40 billion tons are high phosphorus oolitic hematite. Therefore, the
Representative technological samples of iron ore are collected from Eastern South Aswan iron ore mine in Egypt. The principal gangue contents are SiO2 7.76%, and P2O5 1.13%. Iron and phosphorus exist in the form of hematite 78% and apatite respectively. The ore was fired at 1000°C for 3 hours.
