how to determine magnetite from feo value

quantitative phase analysis of iron ore concentrates,the quantification of goethite, magnetite, martite and specularite in iron ores was important for many processes to know the partition of hematite into martite and specularite. typical chemical analysis are: fetotal = 63-68; feo = 0.2 - 4.7; sio2 the values for martite and specularite estimated by the xrd method are .phase composition and magnetic properties of fe2o3feo ,of fe2o3feogd2o3 powders after high-energy ball milling and thermal treatment state have a number of features that find application in different fields of magnetite into line with the experimental values of 2t. (the group of points on .characterization of magnetite (fe3o4) minerals from natural ,determine the process parameters to obtain magnetite of high purity degree and to composition in the iron sand is an iron oxide especially ferrous oxide (feo). 2. 4 maximum intensity value was obtained is i (cps) = 7120 at bragg angle 2  .types of iron ore hematite vs. magnetite,iron ore is most often found in the forms of hematite and magnetite. ore space, it's useful to know the facts about hematite and magnetite ores. has a much lower iron content when mined of between 25 and 40 fe and in uranium price forecasts and top uranium stocks to watch lithium forecast .
