Abstract
Parameters of heterogeneous machining media in magnetic-gravity, gravity and flotation machines are studied using methods of computational fluid dynamics. Numerical modeling of separation processes allowed graphical and numerical characterization of separation. The article bases suggestions on improved designs of the gravity and magnetic-gravity processing equipment and offers approach to evaluating surface energy of mineral particles in flotation modeling.
