The fluorspar flotation concentrate is then processed by magnetic separation, resulting in the desired CaF 2 grade, while the reject fractions are sent back to the primary flowsheet circuit where the REE component is then recovered along with the bulk of the REEs.
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. This product is skimmed off leaving the waste in the bottom of the cell.
The recipe to be used in variable and is based on the charge composition. For example, 1 ton of concentrate or cement can be mixed with 300 kg borax, 100 kg silica, 10 kilos sodium carbonate, 5 kilos sodium nitrate and 0.5 kg fluorspar. As was mentioned before, the flux has influence on the slag properties and Dore bar composition.
The rapid industrialization of the BRIC countries and the reduction of Chinese fluorspar concentrate exports caused the price of fluorspar to increase from $130 per tonne in 2003 to $525 per tonne by 2011. Struggling to cover its needs, China started limiting its fluorspar exports.
