Rao, Bhima R and Veeresh, M B and Reddy, P S R (2000) Flotation Kinetics of Coking Coal Fines. In: International Symposium on Processing of fines. NML Jamshedpur, Jamshedpur, pp. 199-208. ISBN 81-87053-53-4



Investigations were carried out on the coking coal fines generated at Bhelatand Washery. The studies include inve-stigations on physical, chemical and flotation chara-cteristics. Different operating parameters were optimised in flotation to get best product with low ash content. Flotation performance was evaluated by studying the kinetics of different size fractions and also on sample ground for different length of time. Flotation rate constant was calculated using Klimpei's model. Maximum Rate constants were obtained for size fraction -300+150μm (-0.0082)and one minute ground product (-0.0077) with low ash content. From these observations it is concluded that less than one minute grinding is sufficient for these coal fines to achieve a better product with minimum sh.
