Vijaya Kumar, T V and Rao, D S and Rao, S Subba and Bhaskar Raju, G and Prabhakar, S (2005) Beneficiation of a Low Grade Limestone by Flotation Column. In: International Seminar on Mineral Processing Technology(MPT-2005), January 6-8, 2005, Indian School of Mines, Dhanbad.
Beneficiation of a Low-grade limestone sample from Salem, Tamilnadu was carried out by pilot scale flotation column. Mineralogical studies have revealled that quartz, freldspar, pyroxene and biotitic as gangue minerals while pyrite, in trace quantitiew, appear as opaque along with dominating calcite. Reverse flotation was tried using two different commercial amines viz. Chem750F and Flotamine-D. The studies clearly suggest that it is possible to produce a limestone concentrat assying around 96-97% of CaCO3 with less than 1% SiO2.
