Declassified in Part - Sanitized Copy Approved for Release 2012/03/08 : CIA-RDP82-00039R000100200007-2 Flotation of ore with Li.7.5 percent CaF2 and 19.1 percent CaCO3 yielded a concentrate with 97.5 percent CaF2 and 1.0 per? cent CaCO3, with 92.L percent of the total fluorite recovered in the concentrate. These results are much higher than those obtained by Williams and Greeman in their method of flotation with oleic and cresylic acids after preliminary desl.iming. (See Table 221,) FLOTATION AGENTS FOR FLUORITE The flotation of fluorite, like that of many other none- metallic minerals, is done by using carboxylic acids as collectors . In practice, oleic acid or its sodium soap, sodium oleate are the only Collectors whose use is well knotrn in fluorspar flotation mills in actual operation. The flotation of pure fluorite with oleic acid under various conditions is discussed in detail :.i.n the chapter "Flotation of fluorite??. Oleic acid gave most satisfactory re~ suits in testing the amenability of our ores to flotation and left no doubt as to the possibjlilt~r and technical expediency of its use as a. collector for fluorspar. These materials will be e presented in detail below. Sodium oleate gave less favorable results in a number of cases. At the same time there are a number of substantial dish advantages in using oleic acid as a collector. The principal objections are the varying quality of the technical cal product, its sensitiveness to the pulp temperature, its marked sensitiveness ~~WXIi1,.MMiMR N "f y '! X ., dy FN l ~p~ll+` r .
