Mineral beneficiation is the next frontier
A study by economic think tank the Zimbabwe Economic Policy Analysis and Research Unit (ZEPARU) showed that while a number of mines have responded, many others are still far behind. Government's policy position on mineral beneficiation and value addition, ZEPARU added, is aligned with the regional and continental initiatives.

Iron ore beneficiation: an overview
2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.

Mineral beneficiation and ore dressing
Mineral beneficiation is the process of separating economically essential minerals from their respective ores. For example, aluminum is extracted from bauxite ore. Ores are the aggregates of rocks from which the desired minerals are extracted. They can either contain minerals or metals that are economically important to humans.
