Such is the case of this fluorspar ore which is characterized by the presence of a portion of the fluorite in extremely close association with calcium carbonate and silica and containing appreciable clay. High acid grade fluorspar concentrates are difficult to obtain from this class of ores by flotation with an ordinary …
The lead and barite concentrates are dewatered by disc filters and the fluorspar by a drum type fluorspar filter. Concentrate Handling. The filtered lead concentrate drops into bins. The barite and fluorspar pass to rotary dryers provided with dust collecting systems.
The testwork formed the basis of the mineral processing flowsheet used in the Study. The Lassedalen ore is envisaged to be processed using three stage crushing, ball milling, pre-flotation of the sulphide minerals and flotation of the fluorite to produce acid grade fluorspar concentrate assaying 97.5% CaF2.
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.
After a thorough knowledge of the physical characteristics of the ore had been obtained, flotation concentration tests were made to separate the sulfide minerals from the fluorspar and to attempt to prepare lead-zinc and fluorspar concentrates of marketable grade"--Scope of Work Done, page 2.
indicating that secondary enrichment was not a factor in this ore deposit. Production of Fluorspar. The earliest recorded use of nuors];ar was by Agricola, who noted its use as a flux in 1529. In the primitive methods of some of the smelting processes fluorspar was considered an indispensa.ble fluxing ma.terial.
followed by fluorspar flotation, the concentrate analysed 77.94% CaF, with 85.8% CaF_ distribution. Use of warm water in a similar test had given a grade of 70.09% CaF2 with 88.3% CaF1 distribution. Reflotation tests conducted with galena free rougher fluorspar concentrate with 2.25 kg/tonne of sod. silicate after four cleanings, yielded a con-

Aug 23, 1977· More particularly, the invention relates to a method for beneficiating a fluorspar concentrate containing apatite as a gangue mineral, by a froth flotation process. Fluorspar ore commonly contains fluorspar (CaF 2), silica, calcite, clay minerals, and, in certain instances appreciable quantitites of the mineral, apatite (Ca 5 (PO 4) 3 (F,OH ...
A process for producing a fluorspar enriched concentrate having a fluorspar content of at least 97% from a crude fluorspar ore containing in addition to fluorspar appreciable amount of gangue minerals and from 3 to 15% by weight metallic sulfide which consists essentially of a one-step fluorspar flotation circuit comprising mixing the crude ore ...

Fluorspar is an industrial mineral that is composed of calcium fluoride (CaF2), which is made up of 51.1 percent calcium and 48.9 percent fluorine. Fluorspar takes its name from the Latin word "fluo" — which means "flow" — as it lowers the melting point of metal ore and and helps it flow more easily.
