Work Index Of Fluorspar

Bond Work Index - an overview | ScienceDirect Topics

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Fluorspar Statistics and Information - USGS

Fluorspar is used directly or indirectly to manufacture products such as aluminum, gasoline, insulating foams, refrigerants, steel, and uranium fuel. Byproduct fluorosilicic acid production from some phosphoric acid producers supplements fluorspar as a domestic source of fluorine, but is not included in fluorspar production or consumption calculations.

Fluorspar - Industrial Minerals

Market Brief. Fluorspar is the commercial name for fluorite, a form of calcium fluoride (CaF 2).Pure fluorite contains 51.3% calcium and 48.7% fluorine. Fluorite is the primary source of fluorine, however relatively minor sources of fluorine include cryolite (Na 3 AlF 6), sellaite (MgF 2), topaz (Al 2 SiO 4 [F,OH] 2), villiaumite (NaF), bastnasite ([Ce,La][CO 3]F), and fluorapatite (Ca 5 [PO 4 ...
