coal flotation measurements

An XFD flotation machine (Alibaba, Beijing, China) with a cell of 0.5 L was used for coal flotation at a pulp density of 7.8% solids. When DO and OPS was used as a sole collector, the DO dose was 2, 4, 8, 10 and 12 kg t −1, and the dose of OPS was 0.5, 1, 2, 3, and 4 kg t −1

The effect of roughness was eliminated by polishing the surface with 800, 3000, and 5000 grit silicon carbide papers sequentially. The coal powder with particle size below 0.074 mm was obtained from coal lump by crushing, grinding, and sieving. Pyrite powder
