hematite beneficiation ore

Hematite is often cheaper to process than other forms of iron ore as it generally does not require beneficiation due to its higher iron content. However, hematite ores may contain higher concentrations of contaminant elements (such as phosphorus, alumina and silica) and may therefore need to be blended prior to smelting.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

INTRODUCTION India's iron ore reserve is around 25,249 million tonnes (MT) apart from Banded Hematite- Quartzite (BHQ) and Banded Hematite Jasper (BHJ) and occupies sixth position in the world iron ore reserves.[1, 2] Although India is blessed with large reserves of iron ore, a substantial amount of these iron ores are unsuitable for direct use in the blast furnace because of high amounts of ...

24-06-2021· High alumina & silica content of Indian Iron ore resources require suitable beneficiation techniques to produce quality raw material for steel manufacturing. Banded Hematite Jasper (BHJ) reserves are abundantly available in India but not considered as an ore of Iron for production purposes due to its high Silica content and complex mineralogy.

19-04-2016· Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with "Sub-A" Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 …

Hematite is the most abundant iron ore mineral present in available resources while the major impurities include silica, alumina, calcite, clay matter, and phosphorus.
