以煤焦油为原料低温乳化制备煤炭浮选剂,研究不同因素对煤焦油乳液性质的影响。此外,将所制备的煤炭浮选剂与煤油的浮选性能进行对比。结果表明:所制备的焦油乳液浮选性能与煤油相当,但选择性优于煤油,同时油用量大大下降,既降低了浮选成本,又为煤焦油的综合利用开辟了新途径。
The coal flotation agent was prepared by low temperature emulsification of coal tar, and the influence of different factors on the properties of coal tar emulsion was studied. In addition, the flotation performance of the prepared coal flotation agent and kerosene were compared. The results show that the prepared tar emulsion has the same flotation performance as kerosene, but its selectivity is better than that of kerosene. Meanwhile, the amount of oil used is greatly reduced, which not only reduces the flotation cost but also opens up a new way for the comprehensive utilization of coal tar.
