In this study, OBHA was used as collector for the flotation separation of fluorite and calcite. Under a natural slurry pH environment, the recovery of fluorite reached 80 % while calcite recovery was less than 5 % with 3 × 10 −4 mol/L OBHA. The flotation separation of fluorite from calcite can be achieved without the addition of depressants.

Minerals | Free Full-Text | Reverse Flotation Separation of Fluorite
Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP …

Flotation
According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.

Bastnaesite Beneficiation by Froth Flotation and Gravity Separation
Froth flotation is a separation method that changes the surface chemistry of desired minerals, rendering them hydrophobic which allows the desired minerals to attach to air bubbles and float to the surface of the water, forming a froth. Collectors are the primary chemical added into the system to aid in flotation.
