For this purpose, the chalcopyrite was mechanically prepared (crushing and grinding), the material was classified (between mesh 100 and 120 and the particle sizes were measured).

Iron ore mining and dressing - tec-science

In froth flotation, the different wettability of the substances is used for separation! For this purpose, the ground ores (obtained by crushing and grinding) are mixed with water in froth flotation cells. This aqueous suspension is also called slurry. Gas bubbles are generated in the slurry by air supply or stirrers on the floor.
