We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, asphalt, gravel, concrete, etc.
Rao 1986 to predict the yield of concentrate and its ash content. Vanangamudi et al 1987 also showed that an increase in the content of fines during the feed to flotation process decreases the maximum recovery of non-ash material that may be obtained and retards the flotation rate of coarser particles.
A non-coking coal sample of vitrinite type from India was ground to 44 181m d80 and subjected to column flotation to improve its quality. The non-coking coal analyzing 34.6 ash, 26.2 volatile matter, 1.3 moisture and 37.9 fixed carbon could be upgraded to a concentratefroth of 14.83 ash at 72.
The process is based on treating the high-ash thermal coal for reducing the ash level by adopting the gravity concentration and flotation techniques. The ash level can be reduced to 10-15 from a feed of 30-35 ash depending on the coal characteristics. 5. LevelScale of Development. The process has been developed on 5 tpd scale.

This paper tries to determine an optimum condition for the flotation operation of the Alborz-Sharghi coal washing plant. For this purpose, a series of comprehensive experiments have been conducted on representative samples from feed of the flotation system of the plant.
In this study, sorbitan monooleate was used to pretreat lignite prior to flotation tests. First, the lignite sample and water were mixed with 0, 0.5, 1, 1.5 and 2 on the basis of the weight of the coal of sorbitan monooleate to produce five types of flotation slurries.
Two Indian coals were kept for a period of 2 months, and different coal properties such as free swelling index FSI, ash, and slurry pH were monitored at different intervals.
Combustible matter recovery of anthracite coal of mild oxidation, ground by 30 minutes, can reach 72.14 with ash content of 8.63, while combustible matter recovery of original coal is 56.65 with ash content of 9.90.
India Limited, 2014. In order to meet the requirement of low ash coal the Indian Steel industries depend heavily on the imported coal. This has led to a situation where more impetus is being given to clean the inferior grade coals. The Indian Steel industries are trying to maximize the recovery of clean coal from their captive coal mines.
flotation column are reported in Table 4. It is possible to reduce ash from 40 to 24.6 with carbon recovery of 60 in conventional cell by two stage flotation. Whereas a product with 18 ash can be obtained with 60 recovery in two stages in flotation column and a product with 21.
Many scholars have explored the flotation process of oxidized coal and coal with a high ash content using ultrasonic treatment.
Technology of Sulphidisation and Flotation of Non-Sulphide Minerals with Sodium Polysulphides Ash Flotation for Fine Coal Cleaning. Jiang, L. Ye, Chalcopyrite Flotation and Liberation Characteristics Before and After Autogenous Grinding at Mount Isa Mines Limited.
Technical Problems Envisaged for washing Non-coking coals. Non coking coals available in India are of high ash 40 to 50 or more, less matured Ro 0.8 or less. Thus, they are less hydrophobic in particulate surface character than that of coking coals.
The present manuscript is aimed at generating low ash 10 clean coal from high ash 28.88 non coking coal. The coal was characterised thoroughly in terms of petrography characteristics, size analysis, washability and chemical composition and the gross calorific value of the coal was observed to be 5327 Kcalkg.
