【摘要】：浮選是分離微細粒礦物的主要分選方法。微細粒礦物質(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。從動力學(xué)角度,將經(jīng)典微觀浮選動力學(xué)與湍流理論結(jié)合起來,計算了不同湍流強度下微細粒礦物與氣泡的礦化反應(yīng)效率,分析了微觀湍流對微細粒礦物浮選動力學(xué)行為的影響,得到不同湍流強度下的礦化反應(yīng)規(guī)律,并探討了強化微細�；厥盏耐牧鞣椒ā�
[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.
