Limestone deposits are widely distributed in India but high grade deposits are confined to Rajasthan, Gujarat and Jammu & Kashmir. Limestone is mainly used in the manufacture of cement, steel and chemical industries. High grade deposits are depleting and the requirement of the industry has to be met by beneficiating the low grade deposits.The paper deals with the results of froth flotation studies carried out on a limestone sample from Kota, Rajasthan. The sample analysed 41.45% CaO and 13.52% SiO,. Flotation experiments were conducted at different feed sizes, reagent dosages and cleanings. The final concentrate obtained at 86.2% -105 pnt size analysed 50.15% CaO. 5.01% SiO, by using 3.6 kg/t sodium silicate and 1.0 kg/t oleic acid adopting flotation with four cleanings.
