AO捕收剂浮选稀缺难浮煤实验
Flotation experiment of scarce difficult-to-float fine coals floated by collector AO
摘要
Abstract
This paper is an attempt to develop a collector AO designed for addressing the low recovery rate of the scarce difficult-to-float fine coals. The development involves comparing the effect and speed of flotation and the wetting heat of using AO, kerosene and diesel oil by flotation and wetting heat experiment. The results show that the best parameters of the scarce difficult-to-float fine coals floated by the collector AO are that the mass ratio of the collector with the blowing agent is 3: 1, the total amount of the collector and the blowing agent is 1.28 kg/t and the pulp concentration is 75 g/L. In the case of similar clean coal ash content, AO collector gives 11.33% and 14.94% higher clean coal yield, and 6. 18% and 8.09% higher perfect index flotation, than the kerosene and diesel oile respectively. The AO collector shows the fastest recovery speed and the biggest wetting heat. The results of confirmatory flotation experiments have further shown that the collector AO was an ideal flotation reagent with the value of practical application.关键词
