  • Improving flotation separation of apatite from dolomite ...

    2020-09-01  Froth flotation is widely used as an effective method for separating apatite from dolomite. However, it is of difficulty to realize the efficient separation of apatite and dolomite using the traditional fatty acid collectors without any depressants due to their similar physicochemical properties.

    Apatite is found in sedimentary, metamorphic, igneous, and volcanic rocks. Apatite can form in sedimentary processes, igneous processes (e.g., Pegmatite), metamorphic processes, and in hydrothermal vents, as well as production by biological systems. Apatite is one of a few minerals produced and used by biological micro-environmental systems. Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the majo

    In my experience, the precision of mineral separation at this step isn't that great. Zircon apatite are fairly easy to get, but not from each other, or from dreadful pyrite. I've just hand-picked at this stage; a few times I attempted to dissolve the pyrite in nitric acid. But if you want something more mid-range from the magnet (e.g., sphene, rutile, monazite) it can be a major pain. I'm ...
