Abstract
We have developed a method for the calculation of contact angle of spherical particle in interaction with a bubble
in the process of flotation. The balance of forces acting on the instantaneous TPC perimeter in the radial direction
could connect the central angle α and the contact angle θ in only one equation depending on the modified Bond
number Bo, which made it possible to couple this equation with the one of the contact angle in function of the linear
tension. Some theoretical results are presented.
