Abstract
India is importing coking coal from various countries mainly to cater the needs of various industries. One of the supplies from Khazikistan having good coking coal reserves are yet to be fully exploited. Froth flotation studies were carried out on the coal fines generated by crushing the ROM coal to 50 mm. Froth flotation tests were performed with standard dosages on raw coal fines and also on the different size fractions. This article describes the flotation characteristics of a typical coking coal from the coalfields of Khazikistan aiming at 10% ash level in the clean coal. Laboratory flotation tests were used to determine the yield of clean coal of 77% at 10% ash content. The coking propensities of the clean coal strongly support its use as blendable coal for the metallurgical purposes.
