颗粒向气泡选择性的附着,是所有浮选分离中至关重要的一个阶段。附着表示固-液-气三相接触的形成。当疏水平面与液滴形成接触角时,由于三相发生接触,该可量度的接触角的形成,被认为是浮选所必需的先决条件。逐渐变得明显的是,接触角的大 The selective attachment of particles to the bubble is a crucial stage in all flotation separation. Attachment means solid-liquid-gas three-phase contact formation. When the hydrophobic plane forms a contact angle with a droplet, the formation of such a measurable contact angle is considered to be a necessary prerequisite for flotation due to the three-phase contact. Gradually became apparent that the contact angle of the large
