Hematite

Hematite

Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe 2 O 3 and has been widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 176;C (1,740 176;F).

It is the most effective way in processing hematite. Magnetizing roasting is accepted when minerals component is complex or other mineral processing technology cant reach fine processing index. Weak magnetic strong magnetic separation. It is the tradition processing technology dealing with magnetite and hematite mixed ores.

A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006. 7.4. Hematite ore of particle size 4000 microns is to be ground dry to 200 microns (P 80). The work index of the ore was determined and found to be equal to 15.1 kWh/t. Balls of diameter 110 mm were added as the grinding media. The mill was rotated at 68 % of the critical

Hematite The mineral hematite information and pictures

Hematite is one of the most common minerals. The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals. Noncrystalline forms of Hematite may be transformations of the mineral Limonite that lost water, possibly due to

Hematite Processing by Flotation

Hematite Processing by Flotation

The Flowsheet for Hematite Benefication Process by Flotation The above flowsheet has been developed to produce a high grade product economically with maximum recovery. Due to the flexibility of Units and especially the SubA Flotation Machine, gravity flow can be utilized throughout the mill, thus keeping pumping requirements to a minimum.
