Recovery of coal fines from coal waste slurry by oil agglomeration process using linseed oil

摘要

The coal fines from Jamadoba Coal Preparation Plant was used for coal oil agglomeration, and the effect of pulp density (PD), oil dosage (OD), agglomeration time (AT), and particle size (PS) were investigated using linseed oil as bridging liquid. The results were evaluated based on % ash rejection (% AR) and % organic matter recovery (% OMR). The maximum % AR and % OMR were achieved at low PD (3%), high OD (15%), high AT (15 min), and low PS (75 mu m).
