摘    要：本文研究了-5微米粒级黑钨矿的载体浮选,并与同条件下的常规浮选作了比较.所加入载体为大于10微米的不同粒级黑钨矿。发现加入粗粒载体后明显地提高了-5微米粒级的回收率,其原因主要是在强烈的湍流状态下疏水性颗粒之间的“碰撞—粘附”,从而提高了微细粒级的浮选速率,而“碰撞—粘附”过程又受到有关几何、物理、化学因素的互相制约。

Abstract: Carrier flotation of -5μm wolframite is studied in the paper and a corn- parison with conventional fletation in the same condition is made.The car- riers added are coarse minerals of different size wolframites of more than 10μm.It is found that with the addition of coarse carrier particles,the recov- cry of -5μm wolframite is obviously improved because “Collision-Adhesion” between the hydrophobic fine particles and carrier particles leads to an in- creasein flotation rate of the fine particles under the turbulence condition and that the “Collision-Adhesion” process is controlled by relevant parameters in geometry,physics and chemistry.
