denal et al., 1994]. This process couples dolomite dissolution with calcite precipitation and magnesium liber-ation into the solution. Evamy [1967] described dedolomit-ization as a one-step process in which dolomite is replaced by the formation of calcite. In contrast, Kenny [1992] considers dedolomitization as a two-step process, involving

In the field of mineral processing, the successful flotation of target minerals requires sufficient liberation through grinding. The aim of this paper is to compare and evaluate the performance of ball versus short cylindrical media for comminution of dolomite by point and line contact, respectively. The results of the grinding experiments indicate …
