泡沫浮选是使矿浆中的矿粒附着于气泡并随气泡致矿浆面上。实现上述过程必需符合热力学定律。 把单位面积上能量的变化转换成作功情况,则 W_(?)′为粘附功,其大小表示要破坏气—团接触所必须消耗的功。因此可以用它来量度矿粒与气泡的附着强度,但(2)式中的δ_(c-s)目前尚难以测定,无法确定W_(?)′可利用Young公式将(2)式转换成: Froth flotation is the mineral particles in the ore attached to the bubble and bubble to the pulp surface. To achieve the above process must comply with the laws of thermodynamics. Transforming the change in energy per unit area into a work case, W_ (?) ’Is the work of adhesion, the size of which represents the work that must be consumed to destroy the gas-mass contact. Therefore, it can be used to measure the adhesion strength of ore particles and bubbles. However, δ_ (c-s) in the formula (2) is still difficult to measure at present and can not be determined.
