The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation. Furthermore, flotation cells are sensitive to solid overloading. Another relevant process parameter is therefore the solid concentration of the ore suspensions fed to the flotation cells.

· HPGRs can handle a wide variety of ores and particle sizes, from fine pellet feed all the way up to coarse grinding of 75mm magnetite iron ore. Alongside their greater tolerance for ores of different hardness and variable roller speed, HPGRs promote greater flexibility in feed conditions and circuit design than traditional mills.

In the latter, the extraction of minerals from ore requires comminution,, grinding the ore into fine particles to facilitate extraction of the target element (s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres.
