The basic property of the lignite and its pyrolysis products were studied by proximate and ultimate analysis. The effect of collector types on the flotation performance of semi-coke was studied. The results showed that collector consumption of semi-coke was much higher when compared with coking coals due to the larger surface area and a large amount of oxygen functional groups. The semi-coke exhibited a good flotation performance with the emulsified collector at an economical collector consumption.
