【摘要】:浮選是分離微細(xì)粒礦物的主要分選方法。微細(xì)粒礦物質(zhì)量小、慣性低,難以與氣泡發(fā)生礦化反應(yīng),是浮選回收率低的主要原因之一。從動(dòng)力學(xué)角度,將經(jīng)典微觀浮選動(dòng)力學(xué)與湍流理論結(jié)合起來(lái),計(jì)算了不同湍流強(qiáng)度下微細(xì)粒礦物與氣泡的礦化反應(yīng)效率,分析了微觀湍流對(duì)微細(xì)粒礦物浮選動(dòng)力學(xué)行為的影響,得到不同湍流強(qiáng)度下的礦化反應(yīng)規(guī)律,并探討了強(qiáng)化微細(xì);厥盏耐牧鞣椒。
[Abstract]:Flotation is the main separation method for the separation of fine-grained minerals. One of the main reasons for the low recovery rate of flotation is the small amount of fine minerals and low inertia, which makes it difficult to mineralize with bubbles. From the kinetic point of view, the classical micro flotation dynamics and turbulence theory are combined to calculate the mineralization efficiency of fine mineral and bubble under different turbulence intensity, and the effect of micro turbulence on the dynamic behavior of micro particle flotation is analyzed. The mineralization reaction law under different turbulence intensity was obtained, and the turbulent method for enhancing the recovery of fine particles was discussed.
