Dec 30, 1990 Flotation is the dominant process, especially for the production of high-grade concen- trates (acid-grade fluorite). About 25 to 30% of the concentrates come from gravity concentration (lumps, gravel). In flotation, however, an important problem is that the reagent regime has to be continually fitted to changing ore properties
History of Mining in the North Pennines - Fluorspar
Though there is speculation that mining in the Northern Pennines may date back to Roman times, the first documented evidence of mining in the area dates from the twelfth century, and records the presence of silver mines (most likely reflecting early attempts to de-silver galena) in the areas of what are now Alston Moor and Northumberland (King 1982).
