a) Reduction roasting & beneficiation of low-grade hematite \/ limonite \/ goethite ores or tailings (35-55% Fe grades) into magnetite ore, using a fluid bed roaster & subsequent pelletisation in the vertical shaft kiln \u2013<\/p>\n

\"\"<\/p>\n

We offer a new technology from China, which can beneficiate low grades of hematite \/ limonite \/ goethite ores (including BHQ & BHJ) and also recover the left-over tailings from the conventional beneficiation plants, by converting them into magnetite ores, using the fluidised bed reduction-roasting method.\u00a0 Once the iron ore becomes magnetite, it is much easier to beneficiate & pelletise the same.<\/p>\n

The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants)\u2026\u2026.\u00a0Click here for more details<\/u><\/a><\/strong><\/p>\n

b) Reduction roasting & beneficiation of low-grade Ferruginous manganese ores, using a fluid bed roaster & subsequent briquetting.<\/p>\n

C) Dry beneficiation of contaminated iron ore fines (0-2 mm sizes), using a very high gauss rare earth rare earth dry magnetic separator \u2013<\/p>\n

We offer dry beneficiation plants to up-grade the contaminated hematite iron ores. In the dry beneficiation process, iron ore is ground to 0-2 mm size. After screening, the fines are passed through a very high gauss rare earth magnetic separator (up to 8,000 gauss). A demo plant has been set up & experiments on many types of raw materials were carried out in the last 5 years, which have proven that up-gradation of Fe from 50-52% to 56-60% Fe\u00a0 is possible. The non-mag contains 20-40% Fe. The technology is also suitable for pre-separation of contaminants such as silica & alumina from low grade ores of larger sizes\u2026\u2026\u00a0Click here for more details<\/u><\/a><\/strong><\/p>\n
