Huang Kaiguo Li Longfeng Zhang Guoxiang Mineral Engineering Institute of Mining and Metallurgy CENTRAL substituted with conventional flotation sludge flotation of coal flotation stream branch laboratory tests, yy flotation agent to replace diesel oil, pine oil instead of with P8201 octanol or the like, comparative tests The effects are shown in Tables 1 and 2. Table 1 Comparison test of drugs Dosage amount (kg/ton) name Yield(%) Ash (%) Yy oil 1.3 Secondary octanol 0.2 Clean coal 93.7 8.15 Tailing coal 6.3 54.95 raw coal 100.0 11.10 Yy oil 1.3 P8201 0.2 Clean coal 95.6 8.47 Tailing coal 4.4 63.87 raw coal 100.0 10.91 Diesel 1.3 P8201 0.2 Clean coal 94.1 8.12 Tailing coal 5.9 55.97 raw coal 100.0 10.94 Diesel 1.3 Secondary octanol 0.2 Clean coal 92.0 8.03 Tailing coal 8.0 47.85 raw coal 100.0 11.22 Diesel 1.3 Pine oil 0.2 Clean coal 93.4 8.20 Tailing coal 6.6 50.46 raw coal 100.0 10.99 Table 2 Comparison results of branch stream flotation and conventional flotation Flotation process Dosage amount (kg/ton) name Yield(%) Ash (%) Conventional flotation Diesel 1.3 Secondary octanol 0.2 Clean coal 92.4 8.29 Tailing coal 7.6 48.22 raw coal 100.0 11.32 Branch stream flotation Diesel 0.84 Octyl alcohol 0.14 Clean coal 9.21 7.92 Tailing coal 7.90 51.56 raw coal 100.0 11.37 Branch stream flotation Yy油 0.84 Octyl alcohol 0.14 Clean coal 92.50 7.87 Tailing coal 7.5 56.03 raw coal 100.0 11.38 From the test results, we can see: 1. The flotation flotation adopts a new process of branch flow flotation, and the fuel consumption is reduced from 1.5 kg/ton to 0.98 kg/ton, saving 1/3 of the consumption. The clean coal ash decreased from 8.29% to 7.87~7.92%, which improved the quality of clean coal. 2. The flotation of coal slurry adopts the new agent yy oil-P8201, and the yield of refined coal can be increased by 3% to 95.6%. 3. Coal flotation flotation adopts a new process, a branch flow flotation and a new agent, yy oil-P820l, which is expected to reduce the consumption of chemicals, improve the yield of clean coal, and improve the quality of clean coal. This is of great significance for the development of China's energy industry.
