Gravity Concentrators
Because gravity concentrators rely on gravity to generate centrifugal force down the spiral, gravity concentrators do not require electricity to operate, and do not contain moving parts. The result is a reliable, low-maintenance solution to slurry classification. Compact gravity concentrator designs increase available floor space and lower ...

Fluorspar Extraction Processing Flowsheet
Fluorspar is found generally in veins, in gneiss, slate, limestone, crystalline limestone, and sandstone; often as gangue of metal ores, particularly of lead ores. It is sometimes mixed with barite and celestite; and as these minerals are partly sulphur in composition, they lower the value of fluorspar, as sulphur is injurious to iron and steel.
