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 determined. Initially, the iron ore samples contained 34 wt. % Fe in addition to other gangue materials. Therefore, the ore was subjected to a high-temperature …

Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the …

Iron ore assayed 59.02% Fe, 3.64% alumina, 3.87% Silica and 6.11% LOI. Proximate of coal and iron ore analysis was carried out and the result are shown in Table 1. Iron ore and non coking coal were crushed and ground to proper size. Mineralogical studies of iron ore fines by optical microscope was carried out.

Iron ore. Recent increase in demand for steel & increase in its costs has boosted up the production of iron & steel. The demand for iron ore also has sharply increased. The good quality iron ore is fast depleting thereby forcing the iron makers …

Appropriate beneficiation process has to be advanced to reduce the waste generation in mines and for the sustainable growth of the iron ore industry some. Major reason for difficulty in …
