A Sample of fluorspar from Ramorwali mine, Rajasthan, received for beneficiation tests assayed CaF2, 21.14%; SiO2, 53.80% ;CaCO3, 2.10%;Al2O3, 10.02%;Fe2O3,0.7%,Pb,0.31%;and S, 0.12% with traces of Zn, Ba, Cu and W. The principal gangue, minerals were quartz, feldspar and muscovite with minor amounts of calcite, galena, biotite etc. Xanthate flotation for the removal of galena followed by fatty acid flotation for fluorspar, after desliming, produced a rougher fluorspar float assaying 70.09% CaF2 and 0.12% Pb with a recovery of 88.3% CaF2 . One cleaning and four cleanings of the rougher float yielded concentrates of metallurgical and acid grades assaying 84.9 and 49.4% CaF2 with recoveries of 87.2 and 49.4% CaF2 respectively.
