of fine tailing in Özberil Coal Washing Plant (Kale-Denizli) and used for laboratory scale tests. Total amount of samples used in the laboratory tests were about 150 liters. Chemical analysis indicated that sample also contained clay minerals besides coal particles and magnetite .
----- -19- APPROACH Magnetite recovery in a heavy-medium coal-washing plant is generally performed by drain and rinse screens and drum magnetic separators. As finer sizes of coal are washed, new techniques will be used.
The dense medium separation process used in most coal washing and magnetic separation plants requires a suspension of finely milled magnetite in water. Magnetite for coal washing must be of overall high purity and be devoid of contaminants, such as hematite, sulphides or other minerals.
It is believed that this is the cause for much of the loss of heavy media experienced in the coal cleaning plants. Reduction of Fe 2 O 3 to Fe 3 O 4 by controlled heating of the magnetite in hydrogen increases the magnetization and points out a possible method which may be used to reduce plant losses.
The magnetite can be reused in this process 90 percent of the time. Magnetite is also used as a source of iron to manufacture iron-based chemicals and fertilizers. Ferric chloride and ferric sulphate are manufactured with magnetite as one of the starting materials. These chemicals are effective in clarifying raw water in water purification plants.

heavy media process. In India in 80% cases the heavy media used is magnetite. The paper essentially deals with the magnetite stability factors, its preparation and recovery processes, its operational uti-lization and the existing systems in some Indian coal washing plants. A case study to operating system has been made with a view to
Magnetite is a natural aggregate manufactured from the iron oxide Magnetite. With its high specific gravity Magnetite is used as a coarse material to produce heavyweight concrete. When used as the aggregate portion of a concrete mix, magnetite increases the density of the concrete to twice that of standard concrete.

Medium density control for coal washing dense medium cyclone circuits Lijun Zhang, Xiaohua Xia, Fellow, IEEE, Jiangfeng Zhang, Member, IEEE Abstract—The dense medium cyclone (DMC) process used in coal beneficiation plants is studied from a control system perspective. Employing the dynamic model of the DMC process
Global consumption of magnetite in non-metallurgical uses is not precisely known because magnetite production is commonly reported with other iron oxides such as hematite. In Australia, the major commercial application for magnetite is in the dense-medium washing process used in most coal preparation plants (Doral Resources NL 1990).
Uses for Magnetite. When used as the aggregate portion of a concrete mix, magnetite increases the density of the concrete to twice that of standard concrete. This so called "heavy concrete" has become a common building material in nuclear plants as well as (in brick form) for the mitigation of .

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth.

new dense-medium cyclone plant at Tertre in Belgium to process 10 x 0 mm raw coal. The plant was unique in that the feed to the plant was not de-slimed before processing. The raw coal was mixed with magnetite and gravity-fed to two 500 mm diameter (D) cyclones at a feed pressure of 9D. The minus 0.75 mm coal in the feed drained through
