Abstract
The capacities of mechanical activation by planetary ball milling in terms of dissociation of mineral concretions and tin recovery from mining waste are demonstrated. The modes of the short-term activation treatment in the ball mill for higher quality production are determined. The variants of improvement in tin content of concentrates by including milling in hydrochemical concentration circuit are substantiated.
