1.. IntroductionThe flotation of calcium-bearing minerals, including calcite [CaCO 3], fluorite [CaF 2] and apatite [Ca 5 (PO 4) 3 (OH,F,Cl)] is significant for the production of raw materials for the manufacture of fertilizers, cement, fillers etc. The long-chain fatty acids and their alkaline salts, especially oleic acid and sodium oleate have …
