Based on the Fujian coal resource utilization and distribution, samples from Peifeng coal mining were chosen as research object. This paper studies the effects of deashing with oil agglomeration technology, which mainly includes of agglomeration size, coal concentration, oil types and its dosage, alcohol types and dosage, PAM types and dosage. The results showed that the ash content can be reduced from 32% to 2.8% by one time and the ash rejection rate is arrived to 93.0% when the slurry concentration is 11.1% and oil dosage is 12.5%.
