【摘要】：石英砂表面氧化铁薄膜的脱除多采用磁选、擦洗、酸处理等工艺,不同工艺存在对氧化铁薄膜的脱除率低、污染等局限性。以某河砂为试验样,采用超声波法脱除试验样表面氧化铁薄膜,研究了超声波功率、给矿质量分数、处理时间、搅拌作用对试验样中Fe2O3含量的影响。结果表明,超声波功率为550 W,给矿质量分数为45%,处理时间为6 min,磁力搅拌转速为90 r/min时,该试验样中Fe2O3含量可由0.15%降低至0.091%。
[Abstract]:The removal of iron oxide film on quartz sand surface is mostly by magnetic separation, scrubbing, acid treatment and so on. Different processes have some limitations such as low removal rate and pollution of iron oxide film. The influence of ultrasonic power, ore feed mass fraction, treatment time and agitation on the content of Fe2O3 on the surface of a river sand was studied by using ultrasonic wave method to remove the iron oxide film on the surface of the test sample. The results show that the content of Fe2O3 in the sample can be reduced from 0.15% to 0.091% when the ultrasonic power is 550 W, the feed mass fraction is 45W, the treatment time is 6 minutes, and the rotating speed of magnetic stirring is 90 r/min.
