FLUORSPAR | Ares Strategic Mining Inc. | British Columbia
Fluorspar is the predominant commercial source for the chemical element fluorine. Fluorine is a non-metallic element and the lightest of the halogens and therefore largely irreplaceable in its use. There are two principal commercial grades of fluorspar: Metallurgical grade (60-96% CaF2) and acid grade (+97% CaF2).
