Fluorite, CaF2, is considered a strategically important mineral as it is a raw material for many strategic industries. Froth flotation is reported to be the most efficient and economically viable process for the production of an acid grade product with a CaF2 content of at least 97 . Selective flotation of fluorite from gangue minerals, e.g., calcite and barite, is challenging because these
First lets change the amount of the Flotation Depressants used. The valuable mineral that isnt liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that wille most apparent is, that the color of the froth will begin to reflect more of the wanted minerals color. This is because the froth isg purer as
