捕收剂作用下疏水化矿粒间的作用力

INTERACTION FORCES BETWEEN HYDROPHOBIC PARTICLES IN HYDROPHOBIC AGGLOMERATION

根据有关物理化学常数,以黑钨矿疏水性团聚试验为基础,计算和分析疏水化矿粒间的相互作用力。提出在捕收剂作用下微细矿粒发生疏水性团聚时,在各种作用力之中捕收剂烃链间的疏水缔合能和烃链间的范德华引力能占主导地位。

Based on some physical chemistry constants and the experimental da-ta of hydrophobic agglomeration of wolframite fines,the interaction for-ces between the hydrophobic particles are calculated and examined.Itshows that the hydrophobic bonding and the van de Waals force,be-tween the hydrocarbon chains of the collector adsorbed on the particlesurfaces are the dominant ones among those interaction forces in hydro-phobic agglomeration.
