beneficiation at present takes place largely in countries that have no mineral endowment (Baxter, 2005, p. 25). Mineral beneficiation is defined as the process in which mineral products are transformed through different processes and by adding other inputs (Baissac, et al., 2015, p. 10). Thus, mineral beneficiation, refers to the
