Experimental study on Flotation of Huaibei coking coal using novel collector

In view of the current situation in processing coking coal in Huaibei area, comparative test is made on flotation of the coal using the new collectors BSF 1920 and BSF 1927 and the commonly used diesel, and based on the data relating to concentrate yield and ash, recovery rate of combustible matters, and flotation perfection indicators obtained through the test, the flotation performance that can be attained with each kind of collector under varying dosages is analyzed. Comparison shows that: with the use of frother and diesel at dosages of 60 g/t and 400 g/t respectively, the yield and ash of flotation concentrate are 50.95% and 10.00% respectively with a combustible matter recovery rate of 60.24% and a floatation perfection indes of 38.93%; with the use of BSF 1920 at a dosage of 400 g/t, the above-cited figures are 70.03%, 11.86%, 81.10% and 46.34% respectively; and when BSF is used at a dosage of 300 g/t, the figures are respectively 67.10%, 10.88%, 78.96% and 48.69%.
