Quantification of Moisture Contents in Iron and Manganese Ores

Quantification Of Moisture Contents In Iron And Manganese Ores

hematitic iron-rich ores are becoming scarce worldwide and hence new mines are being developed to process ores with low iron contents. these ores normally consist of a mixture of hematite, martite, magnetite, goethite and quartz (major constituents) and kaolinite, gibbsite, siderite, along with many other minor phases.,synthesis of magnetite powder from the mixture consisting,in contrast, ore is difficult to beneficiate if it contains weakly magnetic siderite (feco 3), goethite (feooh), or hematite (fe 2 o 3) as a main iron-bearing mineral. the aim of beneficiation is to remove undesired impurities and to increase the concentration of iron.
