· Coal mining - Coal mining - Coal deposits: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases. The initial product of this ...

Sales during the period were 42,958 tonnes of dense medium magnetite for use in coal washeries. Comparative sales figures are as follows: Iron Ore Fines Tonnes Scheelite M.T.U. Period Ended 30 June 2015 31 March 2015 30 June 2014 Exploration Magnetite
Australian scheelite and magnetite producer Tasmania Mines lifted Sept qtr (Q3) production of dense medium magnetite for use in coal washeries from its Kara No 1 mine to 109,523t, up from 83,832oz in the previous period.Sales improved to 50,649t dense medium
· Magnetite, slurried in water, is used to create an apparent heavy medium in which fine coal (0.1 to 2.4 mm) is cleaned of its mineral impurities. The magnetite is much finer in size (1 to 44 ..mu..m) than the coal and is usually recovered from the coal and refuse
Magnetite is used for the preparation of heavy media in coal washing plants. Iron fines are also used in pipe coating.
Most of the iron and steel industry''s emissions occur during production of iron in the blast furnace, where coal and coke are used as fuel and as a reducing agent. Magnetite has low external fuel requirements during induration as it is exothermic, releasing latent
The use of different underflow configurations caused a variation in the pulp and solids splits, which changed the clean-coal yield and the magnetite-to-coal ratio ofmore » Flotation was used to separate the clean coal and to recover the magnetite contained in the cyclone overflow stream.
· Razorback is what Magnetite Mines dubs a "globally unique opportunity" and that''s because it has the potential to produce the highest grade of any iron ore operation in Australia as well as globally. Lab tests undertaken by the company have already demonstrated it can produce grades of nearly 70 per cent. It has all the right ingredients ...
SAMC member Magnetite Mines says Shagang aims to use the magnetite to blend wint and improve the quality of its sinter plant feed. As with its previous deals, it''s intended the contract will become part of the security package for financing its first production.
· Implementation of the above recommendations reduced the magnetite losses in the coal washing plants from about 1.64 kg/t to 1.3 kg/t. This in terms of raw coal processed in the cyclone circuit reduced the magnetite consumption by 639 t, resulting in a savings of US$27,500/annum. The cost savings are shown in Table 5.
Magnetite losses are generally significant in commercial coal cleaning plants using high-density medium techniques. It is common practice to monitor the cleaned coal, slurries, and refuse using a Davis Tube method in order to isolate and correct unnecessary losses.
