The ore is now ready for flotation. Flotation is the process that concentrates the ore. This is done by agitating the ore slurry in cells with air bubbles. By adding a combination of fatty acid reagents, the fluorspar in the ore attaches itself to the air bubble to float to the top of the cell.

Sep 30, 2019 · "The first stage is known as rougher flotation; after that, the ore goes through a further six stages of cleaner flotation. The cleaner tailings are reground and refloated. This product joins the mainstream acidspar circuit. The refloat tails and first cleaner tails are processed and used to produce Metspar, a lowergrade fluorspar product.

The ore was processed at Teplice using two flotation lines each with 17 cells and using dense media separation to process metspar. However, the 1990s saw major changes Chinese imports, domestic industry restructuring, declining use of metspar in steel plants, HF manufacture ceased which eventually closed the mines in 1995.
