coal processing pyrite

Coal Processing

Coal is a highly hygroscopic and porous material. In situ normally it is saturated with water and acts like an aquifer. Water in coal influences many aspects of coal technology, like bulk flow properties, abrasiveness during grinding, spontaneous heating and combustion rates.

Coal Processing

Understanding the mode of occurrence of sulfur in coal is a critical part of quality control and coal processing (see Chapter 3). For some coals, conventional cleaning effectively removes a large percentage of inorganic sulfur associated with sulfides (most commonly pyrite) from the coal.

Mar 23, 2014 coal performance in a particular plant may allow improved coal utilisation as well such as pyrite fes2 which has significance on the coal behaviour in the s opposed to fire passing through the tubes

Comparison Analysis of Coal Biodesulfurization and Coal's

Acidithiobacillus ferrooxidans ( A. ferrooxidans ) was applied in coal biodesulfurization and coal's pyrite bioleaching. The result showed that A. ferrooxidans had significantly promoted the biodesulfurization of coal and bioleaching of coal's pyrite. After 16 days of processing, the total sulfur removal rate of coal was 50.6#x25;, and among them the removal of pyritic sulfur was up to 69

Flotation of Pyrite

As this material contained iron minerals other than pyrite, it was necessary to calculate the pyrite from the ratio FeS2 : S2 = 1.875 : 1, after deducting the sulfur held by the chalcopyrite and sphalerite. According to the above calculation the pyrite content of sample mixture No. 3 is 14.20 per cent. Tests similar to those recorded in Table 5 were made on this material. The results obtained

Flotation of Pyrite

The action of Pentarco Nos. 350 and 400, mixture A, acid sludge, and sulfuric acid on Chestatee pyrite, and Sulphur Mining and Railroad pyrite was similar to their action on Mountain copper pyrite. The finer the material, the greater is the percentage of recovery; the pyrite should pass at least a 170-mesh screen in order to get efficient flotation under the conditions of the tests.

Separation Process of Chalcopyrite, Galenite, Sphalerite

1. The Separation of Chalcopyrite and Pyrite Method It depends on the ore property, including the following two methods: 1.1 Preferential Flotation: This method is suitable for dense lump ores. Under relatively coarse fineness, chalcopyrite and pyrite can be fully dissociated, and separated. Separation Turn: chalcopyrite first, pyrite second.

Study on Mineral Processing Technology of Coal Pyrite in

Based on the analysis of the properties of a high carbon pyrite from Yunnan, a series tests on gravity concentration and flotation were carried out. According to this basis, a closed-circuit flotation test scheme was worked out, which obtained a fine quality pyrite concentrate with a sulfur grade of 38.24%, comprehensive sulfur recovery of 70.87% and carbon content of only 0.87%.
