    2009-8-27Figure 4. If the contact angle is very small, then the bubble does not attach to the surface, while a very large contact angle results in very strong bubble attachment. A contact angle near 90 is sufficient for effective froth flotation in most cases. Figure 4 Contact angle between and air bubble and a solid surface immersed in liquid.
