US2407651A Concentrating fluorspar by froth flotation. The process .of concentrating fluorspar by froth flotation of pulps containing fluorspar values, comprising adding to the pulp a lignin sulphonate, a tannin extract and a fluorspar collecting agent selected from the class consisting of fatty acids and soaps, and subjecting said pulp to froth flotation in the presence of a soluble ...

Flotation of fluorspar must be extremely selective when producing acid grade concentrate. This selectivity is essential as the ratio of concentration is low, often up to 80% or more of the entire tonnage, and must be floated in the rough circuit.

Fluorspar flotation concentrates of acid grade must be dried to less than 0.5% moisture. Dust losses are kept to a minimum by providing a closed system with a cyclone to insure only vapor laden air discharging to the atmosphere.

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.

Reverse cationic flotation batch tests were conducted using 1kg of fluorspar tailings in 2.5l Denver D12 flotation cell at pulp density of 40% solids, impeller speed of 1000rpm and air flowrate of 60%. Before flotation, the pulp was first conditioned with starch for 4min and then conditioned with collector for 4min.
