Efficacy of Pilot Scale Batac Jig on LVC Coal Utilization for Coke Making

The focus of present research is to see the effectiveness of Pilot scale Batac jig for beneficiation of coarse (- 13 + 1 mm) low volatile coking coal from Jharia through a series experimentation wherein appropriate diverse process parameters were exploited for definitive study. The feed coal properties were measured in terms of proximate and ultimate analysis. The gross calorific value was observed as 5784 kcal/kg. The performance of jigging process observed layer wise, evidenced that the stroke length and air pressure of the process parameters were impressively provoking generation in potency of the process. The jigging experiments revealed that 24.6% ash content of concentrate was achieved with 76% yield from the feed ash content of 32.5% in top layers under optimum process conditions, whereas bottom layer contained 57.4% ash as the final reject. The jig product is promising and practicable for assured usage as blendable coking coal for making metallurgical coke.
