Manganese ore is concentrated using multiple methods: gravity, magnetic, and flotation in various combinations. These methods are preceded by the so-called raw ore washing stage, which is of great importance in the general technological scheme of concentration of all types of manganese ore (oxide, mixed, carbonate).

The flotation experiments confirmed that the addition of MnCl2 before sodium silicate showed an adverse effect on flotation and the recovery of scheelite gradually decreased as the amount of MnCl2 was increased. When MnCl2 was added afte r sodium silicate, the recovery of scheelite gradually increased with an increase in the amount of MnCl2.

Manganese can be easily removed using oxidant such as potassium permanganate dosing (Salem, El-Awady, & Amin, 2012). High total dissolved solids content can be removed using reverse osmosis membranes (Fotouhi & Kresic, 2010). Turbidity reduction is done using a sedimentation system or dissolved air flotation system.
In a mixed mineral system, the mineral/solution interface potentials account for the mixed potential which is critical to the process of flotation (Chander, 2003, Hu et al., 2009, Woods, 2003).
