Abstract

India's energy sector is primarily dependent on coal which is the abundant indigenous resource. Such dependence on coal is going to continue in the foreseeable future. Indian coals, which are of Gondwana origin, contain high ash wherein the extraneous material was intimately mixed in the coal matrix during the formation stage, causing a high level of impurities in the run-of-mine (ROM) material. These coals possess difficult to very difficult washabilaity characteristics. Beneficiation of high- ash non-coking coals of India has become the prerequisite for improving the overall economics and efficiency of power generation. The state of Orissa contains approximately 23% of India's reserves of noncoking coal. This paper describes the washability characteristics of non-coking coals from the Talcher Coalfields of Orissa aiming at 34% ash level in the clean coal as per the stipulations laid by environmental gazette notification of Govt. Of India. Conventional float - and - sink testing was carried out to determine the theoretical yield of clean coal at 34% ash content. The washablity data was used for prediction of practical yield which may be achieved by using a Jig washer. Based on the simulated results a conceptual flow sheet was developed.
