Limestone - 48-54% Cao, 85-97% Caco3 Content | Durable, Highly Soluble, Reactive To Acids

Limestone

We are one of the most well known traders and suppliers of Limestone.
We offer our clients superior quality of Limestone, which is
available in different range of finishes like natural, honed, polished
and others. Apart from this, our Limestone is also available in varied
thickness & dimensions, meeting the specific decorative demands of
clients. Natural Limestone contains silica in different proportions and
is largely composed of calcite mineral. The Limestone powder contains
calcite mineral due to the marine organism.

• Limestone containing about 45% CaO and above is usually preferred for the manufacturing of cement.
• Magnesia content in the stone should ideally be less than 3%, although as high as 5% MgO is used by the industry.
• The
  proportion of Al2O3 + Fe2O3: SiO2 should be 1:2:5. Magnesia sulphur and
  phosphorus are regarding as most undesirable impurities.

• Limestone is used in this industry both in the blast furnace to
  lower the temperature of melting and second to from calcium silicate by
  combining with silica of the iron ore, which comes out as slag.
• For
  this purpose good fluxing limestone low in acid constituents such as
  silica, alumina, sulphur and phosphorus is required. The limestone
  should be dense, massive, preferably fine grained, compact and
  non-fretting on burning

• The calcium carbide manufactures generally prefer lime containing 95% CaO (min.), not more than 3% SiO2, not exceed 2%.

• In sugar industry lime is used for the clarification of juice form can be beets.
• Milk of lime 1% in volume of cane juice is added to pre-heated juice.
• Limestone
  to be used in sugar industry must be high in active lime (CaO S 80%
  min.) must be low in iron, alumina and silica, etc.

• Glass industry required high limestone (CaCO3: 94.5%) combine CaCO3 and MgCO3 should be 97.5%.

• 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.)

• CaCO3 : 85-97%
• CaO : 48-54%+
• SiO2 : Below 1%
• 1-1.5
• 1.5-2
• 2-3
• 3-4
