DESIGN AND PERFORMANCE ASPECTS OF COAL

Flotation is commonly used to treat fine coal (typically below 500 microns in size) and is a complex, three-phase process that is controlled by factors which can be divided into three facets: coal, chemistry and machine. It is most often used for treating metallurgical coal fines where the value of the product can justify the added

Flotation behavior of hard-to-separate and high-ash fine coal

Kinetics is an important aspect of fine coal flotation (Wills and Napier-Munn, 2006; Li et al., 2012). The flotation rate determines the time needed for removal of ash from raw coal. Coal particles with different sizes and densities have different flotation rates. Most flotation rate tests show that the fine coal

Process intensification of fine coal separation using two

However, this device may be unsuitable for the coarse particle flotation and has high handling ability. A two-stage flotation column with dimensions of 2 000 mm×1 000 mm×4 000 mm was designed to enhance the column flotation process. The energy input was modified by adjusting the

Utilization of waste coal flotation concentrate for copper

In this work, the process of copper matte smelting with the utilization of a fine-grained coal-bearing material (the so-called coal flotation concentrate) as fuel is presented. This material is obtained by the process of coal sludge utilization, and, currently, it constitutes an undeveloped waste due to environmental restrictions.

The Flotation Process with High Intensity Conditioning and

The properties analyzing of flotation feed sample told that this fine coal sample is high-ash and hard-to-float coal slime. The ash reduction comparison of the step-by-step release flotation test with high intensity conditioning (HIC) or not, and the comparison of flotation test with HIC and adding depressant were made. The results showed that HIC can significantly improve the flotation effect

Beneficiation of an Indian non-coking coal by column flotation

Mechanized coal mining techniques generate large amount of fine particles that have to be recovered in coal washing plants. Fine coal processing has always been a problematic and costlier than the cleaning of coarse coal (Andrew Mohns 1997).Froth flotation technique is an effective and best available technique for cleaning fine coal with particle size less than approximately 0.5 mm (Bensley

Opportunities for fine coal utilisation

Opportunities for fine coal utilisation 7 A considerable proportion of material extracted during coal mining is rejected. This includes material that is largely a by-product of coal processing, having significant energy content and small particle sizes including substantial amounts below 0.15 mm. Such fine coal is difficult to handle and poses

Effect of Nanobubbles on the Flotation Performance of

In this investigation, the flotation behaviors of fresh and oxidized fine coal (<45 μm) and the effect of mixing with coarse particles (250-500 μm) in equal proportions were discussed. Zeta potential and contact angle results indicated the surface hydrophobicity of oxidized fine coal was much lower than that of fresh fine coal.
