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 …
3. Energy requirements3.1.. Theoretical energy requirementsThe minimum (theoretical) energy requirement was calculated by one of the authors and a coworker using a steady-state exergy-balance equation for the entire (from ore to blister) process [3].Empirical data were the ore-grade (1.32%), its mineralogical composition (sulfur ore) …
The overburden/ore ratio is approximately 77/1 [48] in open pit mining. In spite of its fine adhesion (<53 μm) saleable Cu and S concentrates are extracted economically from the extracted ore [49 ...
The specific energy for the concentration of copper from Thanatia is a function of the hardness of the ore, represented by the Bond Index (Wi) and the reduction ratio of the process (Rr). By assuming Wi = 14 kWh/t and Rr = 480 (P80 = 34 μm), the "new ERC from HSC" value obtained was 6576 GJ/t-Cu.
