First, the ore is ground into a fine powder and added to liquids in flotation tanks. Chemicals are added to cause impurities to settle out, and air is pumped in to create air bubbles. The finer bastnaesite particles stick to the bubbles, which rise to the top and form a froth that is then skimmed off.2 The following diagram shows how this works:
