limestone are located all over the country and are being worked out. In addition to this, calcareous material like shells and corals are also worked out on the coastal areas wherever it is necessary. Usual gangue associated with limestone is silica which is removed only by flotation methods. In addition to this, the nature of terrain and the geo-

The lime (CaO) content of the concentrate was further enhanced up to 44.23% at 20.73% yield using single stage column flotation. The column flotation is more efficient in comparison to the conventional cell for treating this sample. A process flowsheet was developed to treat these rejects based on the studies carried out.
One way is to crush the limestone to −3 mm size and then to process it in a scrubber and classifier Another entails grinding the raw feed to less than 200 mesh and then to carry out beneficiation by a froth flotation method In the present case a low grade limestone sample was processed using the column flotation technique.
In general, the process flowsheet for beneficiation of limestone consists of crushing and screening, washing and scrubbing, grinding and classification and flotation . Gravity …
A low grade Limestone from ACC mines, Madukkarai, Coimbatore district, Tamil Nadu, India, was subjected to beneficiation by cationic reverse flotation process with the aim of producing cement grade and metallurgical grade concentrates. The low grade limestone analyzed 43% CaO, 76%TC, 18% SiO 2, 1.3% MgO, 1.30% Fe 2 O 3, 2.50% Al 2 O 3, 0.33% alkalis …
Limestone rejects from Bagalkot mines have been beneficiated by froth flotation with a view to reducing the magnesia content. In order to ascertain the effect of the main parameters such as sodium oleate concentration, sodium silicate concentration and pH on the MgO content, statistically designed experiments have been performed.
