The purpose of this study is to explore the collision–attachment law of lepidolite, feldspar and quartz during their interaction with bubbles by particle settlement method and bubble rising method under the action of combined collector. In this study, HQ-330 and dodecylamine were used as combined collector to separate lepidolite, feldspar and quartz by flotation. It also aims to analyse the relationship between collision probability, attachment probability, formation time of three-phase contact line and flotation recovery and the main factors affecting the formation time of three-phase contact line. Experimental results show that when the pH is 7 and the combined collector dosage is 100 mg/L, the separation of lepidolite from feldspar and quartz can be achieved. In the particle settlement experiments, the correlation between collision probability and flotation recovery is low, the correlation between attachment probability and flotation recovery is positive. In the bubble rising experiments, the formation time of three-phase contact line (tTPC) is negatively correlated with flotation recovery, and the combined collector changes tTPC by changing drainage time.
