Experimental methods Two-step process for the preparation of iron carbide. The preparation of Fe 3C from high phosphorus oolitic hematite at 105 Pa was carried out using a two-step process, which was H 2 reduction and subsequent carburization with CH 4. Firstly, the.The phosphorus extraction was above 80 , reaching final values of 0.018 from an initial value of 0.421 power. Xu et al. 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.

    Beneficiation Study on an Oolitic Hematite - Scientific.Net. High phosphorous oolitic hematite ore is one of typical intractable iron ores in China, and the conventional beneficiation methods are found to be impracticable to remove phosphorus from the ore effectively.The strong global demand for iron and steel has necessitated the utilization of various low grade iron ores, which are not suitable for direct utilization in ironmaking processes. The low grade iron ores cannot be dressed effectively using the traditional mineral processing methods because of complicated min-eral compositions. The main problem associated with exploiting these deposits is the.
