Froth Flotation Principles
One of the most important factors in fluorspar flotation is the selectivity so necessary when making acid grade which in most cases must contain less than 1.5% silica. It is often necessary to clean a large bulk of concentrates several times in order to attain ultimate grade. Flowsheets are now quite common where 7 or 8 cleaning steps are in use.
