Hematite and magnetite are the most important ore minerals in the Indian iron ore deposits. About 59% hematite ore deposits are found in the Eastern Sector and about 92% magnetite ore deposits occur in the Southern Sector, especially in Karnataka. Of these,
Grid power is available within 40km of the deposits and sufficient water can be sourced from ground water aquifers located in the North Carson sink. The Nevada Department of Conservation and Natural Resources has already granted the required water rights for the life of the mine.
Magnetite Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a highly magnetic substance used primarily in steel manufacturing and coal washing. There are more than 20 identified magnetic deposits and prospects located across South
High grade for magnetite deposits with the average grade for the Opaban deposit of 57.3%Fe being almost double that for most magnetite deposits. This means the proportion of ore which reports to the final product is significantly higher than for most other deposits (>60% compared with 30 – 35% for most magnetite deposits).
· Some researchers proposed that the magnetite ore directly crystallized from iron oxide melts, similar to magnetite-apatite deposits (i.e., Kiruna-type; Mucke and Golestaneh, 1982, Mucke and Younessi, 1994). Skarn origin for GGID is also suggested by some, ).
· Iron ore grinding and classification Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits are much finer-grained and therefore require significant grinding to liberate the magnetite from its silicate matrix. Various magnetite
· But in actual fact magnetite can be very profitable for a company. When you mention iron ore, most people think about the BHP''s and Rio Tinto''s of the world that produce the direct shipping stuff and have made billions doing it. But that''s just one avenue to a profitable iron ore business. There are two main types of iron ores ...
Magnetite. Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.

Processing of Magnetite Iron Ores - Comparing Grinding Options. Although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed.

· Ore grade, thickness and size of deposits vary considerably. The orebodies that lend themselves to mining have generally a thickness of 30 to 60 meters grading 30 – 35 % Fe and 0.15 -0.25 % P. The grain size varies from 0.05 to 2.5 millimeters.
· 2.2. Late magmatic iron ore deposits This type of iron ore deposit is associated with the mafic-ultramafic magmatic intrusions of the iron and its iron minerals are rich in vanadium and titanium, commonly referred to as vanadium-titanium magnetite deposits.

Type Of Grinding For Iron Ore. 2019-12-4iron ore mining often focuses on looking for hematite deposits known as red iron ore and magnetite as they have naturally weak magnetic fields that aid in their purificationematite however responds better to the flotation
Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits require significant and different beneficiation, which typically involves grinding of the run-of-mine ore to a particle size where magnetite is liberated from its silicate matrix.

hematite ore deposits are found in the eastern part of India and 82% of magnetite ore deposits occur in southern part of India, especially in the state of Karnataka. India possesses around hematite resources of 11,464 million tons of which 6,013 million
would be on its own by reducing the total installed power by 1/3 and annual grinding media cost by 2/3. INTRODUCTION In the past decade the interest in Australia''s iron ore deposits has shifted to include the vast magnetite deposits scattered throughout

· Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in consumer demands. Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores.
211 Ore and gangue mineralogy and zonation Ore minerals are predominantly magnetite and hematite, less commonly siderite. Gangue is mostly quartz in the form of variably metamorphosed chert beds. Other gangue minerals that might be present, depending on
Braemar ore deposits are unusually soft and only slightly abrasive when compared to typical taconite or BIF deposits. The Braemar deposits therefore offer competitive grinding cost advantages. Braemar magnetite grains occur in a matrix of soft siltstone and shale and break readily along grain boundaries.
· The entire process involves the crushing and grinding of ores to powder form, exposing it to a magnet for separation followed by other agglomeration processes for value addition and onward utilization. Most miners of magnetite ore install a beneficiation and

Magnetite ore and processing A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further
Conversely, fine-grained magnetite ores require fine grinding, often to below 30 μm, to liberate the magnetite from the silica matrix, incurring greater costs and energy consumption. The comminution energy consumption could be over 30 kWh/t, an order of magnitude higher than for hematite ores.
Due to the depleting reserves of DSO ores and increasing development of low-grade hematite and magnetite deposits, the need for iron ore beneficiation is increasing. Even the DSO ores are requiring a higher level of processing as the depth of existing mines is increasing (below water table) where ores are wet and more sticky, which creates challenges for conventional crushing and screening.
· The majority of steel production is supported by iron ore sourced from high-grade hematite deposits, although a significant fraction comes from magnetite deposits. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits require significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix.
