In general, precipitated calcium carbonate (PCC) is used as a mineral filler in paper industries; while natural calcite (CaCO3) ore is also suitable for industrial use if it is a finely ground high-grade material. Naturally, calcite is found in the form of high- or low-grade ores and it is one of the most widely distributed industrial minerals on the earth's crust. However, it is …

The flotation recovery of fluorite is enhanced by mixed adsorption of C 12 sarcosine and C 12 amine collectors. The best recovery in flotation is achieved by 60:40 mol% C 12 sarcosine and C 12 amine.
