Fertilizers Industry : The latest use of limestone introduced in the country is in the manufacture of calcium ammonium fertilizers, limestone is used only as carrier. For this purpose limestone should contain MgCO3 + CaCO3 85% (min.) SiO2 5% (max.) and acid in-soluble 14% (max.) Learn More

How does limestone remove silica

Feb 12, 2020 The calcium carbonate in the limestone reacts with the silicon dioxide to form calcium silicate (also known as slag). Molten calcium silicate is less dense than the molten iron so it floats on top of the iron and can easily be removed. Learn More

Limestone cement and an energy source

Aug 05, 2014 There is a buffer reaction between calcium, SiO2 and CO2. At low temperatures mixtures of CaCO3 and SiO2 are stable, at high temperatures they r)ct, forming CO2 and Wollastonite (CaSiO3) and CO2. There is evidence that this reaction occurs on the surface of Venus. On Earth it occurs in the contact aureoles of igneous intrusions into limestone Learn More
