本文通过油酸钠在黑钨矿表面吸附量的测定及黑钨矿油团聚的试验结果证实,对于不同粒度级别的黑钨矿开始发生球形团聚时,所需要的油酸钠最低用量是当油酸钠在黑钨矿粒子表面产生约为1/2单分子层吸附;当吸附厚度接近一个单分子层吸附时,油团粒度最大,油团生长速度最快,油团效果最佳;而吸附超过单分子层厚度时油团效果变坏。
In this paper, the determination of the amount of sodium oleate adsorbed on wolframite surface and the agglomeration of wolframite oil confirmed that the minimum amount of sodium oleate needed for the wolframite of different particle size classes to begin to spheroidize was that of oil Sodium sate produces approximately 1/2 monolayer adsorption on the surface of wolframite particles. When the adsorption thickness is close to that of a monolayer adsorption, the particle size of the oil is the largest, the fastest growth rate of the oil group is the best, Exceed the monolayer thickness of the oil group becomes bad.
