Limestone beneficiation is a process whereby low-grade material is blended with high-quality, sweetener-grade limestone containing eight per cent silica to enable the use of the material. Cement-grade limestone contains about 11-14 per cent silica, twice as much as the low-grade material. AV Dharmakrishan, CEO of Ramco Cements, said the ...

India: Madras Cements is to set up limestone beneficiation plants to help it improve its cement raw material resources and extend the lifespan of its limestone mines. Once the beneficiation plant is in place, low-grade limestone will be processed to 12.5% SiO2 content. The cement plant will then use equal quantities of beneficiated and high grade limestone.

Abstract Pilot scale column flotation studies were conducted on a low grade siliceous limestone ore. Silica content was reduced to less than 1% in the concentrate so that it became satisfactory for use in the paper or rubber industries. The limestone sample was crystalline and constituted primarily of calcite that contained quartz, feldspar, pyroxene, and biotite as gangue minerals.
