Beneficiation of a siliceous limestone sample Summary: White colored low grade siliceous limestone sample containing 45.10 % CaO and 15.60 % SiO2 from the Jayantipuram mine of Andhra Pradesh/India has been investigated for amenability to beneficiation by flotation. The limestone sample was crystalline and consisted mainly of calcite and quartz.
In India more than 60% of lime stone is used in the manufacture of cement. Other than this, it is widely used in calcium carbide, sugar industries, textile, glass and paper industries, it is also used in blast furnace and steel melting process. Lime stone does not occur in pure form and it is always admixed with the silica, magnesia and iron oxide. …
