ABSTRACT:
Processes by which a mixture of two or more discrete particulate materials, each of said materials having a different sliding coefficient of friction, can be separated using methods which take advantage of velocity differences generated by the application of a force to said mixture to create movement of said mixture over a surface as a function of its sliding coefficient of friction. Various apparatus to effect such processes are also disclosed.
