Concentration of minerals
Minerals often need to be concentrated before metallurgical processes. The concentration can be done by flotation, magnetic and gravity separation or pre-reduction due to the nature and composition of the mineral.

Gravity Concentration of Gold-Bearing Ores and Processing …
Gravity concentration depends on the differences in specific gravity of the mineral of interest and the gangues, the particle size of the gold minerals, and the rheological behavior of the pulp – the settling rates of the individual gold particles (Agorhom and Owusu Citation 2022). Thus, the GRG test has become an industry standard for ...

Process for the concentration of mineral by flotation process
A flotation process for concentrating tungsten or tin ores is achieved by grinding the ores with a grinding medium other than steel, first conditioning a deslimed sulfide free pulp with an acid, further treating the pulp with an emulsified collector and recovering the tungsten or tin in the float. The flotation concentrate can be further enriched by leaching with an inorganic acid.
