This research is aimed at the up-gradation of indigenous Pakistani iron ore, i.e., Dilband iron ore (hematite), by utilizing common metallurgical processes. First, the magnetic properties of the ore were The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process.Iron ore slimes beneficiation using optimised ScienceDirect

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and The blast furnace and direct reduction processes have been the major iron production routes for various iron ores (i.e. goethite, hematite, magnetite, maghemite, siderite, etc.) in the past few decades, but the challenges of maintaining the iron and steel-making processes are enormous. The challenges, such as cumbersome production Recent Trends in the Technologies of the Direct Reduction
