【摘要】 超声处理对煤泥浮选的影响是多方面的。笔者对煤泥超声处理前后浮选的精煤产率、浮选脱硫效果、浮选速度等方面进行了试验研究。试验结果表明,在相同药剂制度情况下,经过超声处理浮选的精煤产率提高了10%以上;浮选脱硫完善度提高了20%;浮选速度也较超声处理前有了明显的提高。更多还原

【Abstract】 The effect of ultrasonic treatment were several sides in slime flotation . The cleaned coal yield before and after ultrasonic treatment, the effect of flotation desulfurization and flotation speed were studied. The result is shown that, at the same regime of agent, the cleaned coal yield increased more than 10% and the perfect degree of flotation desulfurization increased 20% and flotation speed also increased notably as a result of ultrasonic treatment.更多还原
