32 Limestone & Other Calcareous Materials
The term limestone is applied to any calcareous
sedimentary rock consisting essentially of
carbonates. The two most important constituents
are calcite and dolomite. Limestone often contains
magnes ium carbona te , e i ther as do lomi te
CaMg (CO3)
2 or magnesite (MgCO
3) mixed with
calcite. It is then termed 'dolomitic' or 'magnesian'
limestone. Limestones altered by dynamic or
contac t metamorphism become coarse ly
crystalline and are referred to as 'marbles' and
'crystalline limestones'. Other common varieties
of limestones are 'marl', 'oolite' (oolitic limestone),
she l ly l imes tone , a lga l l imes tone , cora l
limestone, pisolitic limestone, crinoidal limestone,
travert ine, onyx, hydraulic l imestone, l i tho
graphic limestone, etc. However, the limestone
which is used by industries in bulk quantity is a
bedded type sedimentary l imestone. Other
calcareous material used by industry is 'chalk',
a white, extremely fine-grained, usually soft
and friable variety of limestone, composed wholly
or largely of microscopic small remains of
foramini fera and broken shel ly f ragments ;
'kankar', irregular nodules and concretions of
impure calcium carbonate of all sizes found
in the o lder sur face a l luv ium or so i l s ;
and 'limeshell', the thick calcareous shells of
molluscs deposited in the form of beds as well
as present in ancient lakes and shallow seas.
A limestone rock which separates well along
the stratification into a few centimetres thick
slabs is termed 'flagstone'. The dimensional
limestone used for building and ornamental
stone purposes is discussed in the Reviews
on 'Marble ' and 'S la te , Sandstone & Other
Dimension Stones'.
RESOURCESThe to ta l resources o f l imes tone of
all categories and grades as per UNFC system as
on 1.4.2010 are estimated at 184,935 million
tonnes, of which 14,926 million tonnes (8%) are
under reserves category and 170,009 million
tonnes (92%) are under remaining resources
category. Karnataka is the leading state having
28% of the to ta l resources fo l lowed by
Andhra Pradesh (20%), Rajas than (12%),
Gujarat (11%) , Meghalaya (9%),Chhattisgarh
(5%) and remain ing 15% by o ther s ta tes .
Gradewise , cement g rade has l ead ing
share of about 69% followed by SMS & BF
grades (12%) and chemical grade (3%). Remaining
16% are others, not-known and unclassified
grades (Table-1(A).
The total resources of chalk of all cate-
gories and grades as per UNFC system as on
1.4.2010 are estimated in Gujarat at 4.92 million
tonnes of which 4.33 mil l ion tonnes (88%)
are under reserves category and 0.59 million
tonnes (12%) are under remaining resources
category (Table-1(B).
The total resources of marl of all categories
and grades as per UNFC system as on 1.4.2010
are estimated in Gujarat State at 151.68 million
tonnes of which 139.98 million tonnes (92%) are
under reserves category and 11.70 million tonnes
(8%) are under remaining resources category
(Table - 1 (C).
EXPLORATION & DEVELOPMENTExploration was carried out by GSI in Andhra
Pradesh, Arunachal Pradesh, Meghalaya and
Rajasthan. Directorates of Mining and Geology
of Himachal Pradesh, Chhattisgarh and Rajasthan
and commiss ionara te o f Geology and
Mining,Gujarat also carried out exploration for
limestone. Details of work carried out are
furnished in Table-2.

Limeshell
The production of limeshell at 18,786 tonnes
during 2013-14 decreased by 22% as compared to
the preceding year due to lower demand in
market.
There were 6 reporting mines in 2013-14 same
as in the p rev ious years . Three p r inc ipa l
producers accounted for 83% of the to ta l
production during the year. The share of public
sector was 45% in 2013-14.
Almost entire production of limeshell was
reported from Kerala and nominal production was
reported by one mine located in Tamil Nadu.
Mine-head stocks of limeshell at the end of
the year 2013-14 was 2,342 tonnes as against 2,539
tonnes in the begining of year (Table - 11).
The average daily employment of labour
during the year 2013-14 was 547 as against 568 in
the previous year.

MINING & MARKETING
In India, limestone mines are worked by
opencast method. Captive mines are mechanised
and supply feed to cement and iron & steel units.
Some mines have well laid road-cum-rail routes
and aer ia l ropeways . The la rge mines a re
developed by forming benches in overburden and
limestone bed. The face length, width and height
of the benches cor respond to the min ing
machinery deployed and production schedule.
Heavy earth-moving machinery like 3.3 to 4 cu m
capacity hydraulic excavators in combination with
10-35 tonnes dumpers are normally used. Other
mines are mainly worked by semi-mechanised and
manual opencast mining methods.
In Andhra Pradesh, limestone production
from Adilabad and Kurnool districts is used in
paper mills, sugar, cement and steel plants. Tile,
mossaic, chip and polished stonemakers also use
limestone.
LIMESTONE AND OTHER CALCAREOUS MATERIALS
32-29
Limestone produced in Bihar is supplied
mainly to cement plants, foundries and lime kiln
units.
In Raipur and Durg districts of Chhattisgarh,
the limestone produced is suitable for Iron & Steel
Industry. The Bhilai Steel Plant obtains i ts
requirements of limestone from Nandini mines in
Durg district. The cement grade limestone is also
produced in the region.
Limestone produced in Gujarat is consumed
mainly in cement and chemical industries and also
in textile, foundries and steel plants. The dolomitic
limestone in Gujarat is used for making slabs and
tiles.
Limestone produced in Himachal Pradesh is
supplied to cement plants, paper industry, sugar
mills and lime kilns. The production from Bilaspur
district is despatched to fertilizer unit of National
Fertilizers Ltd, (NFL) at Naya Nangal.
Limestone produced in Jammu & Kashmir is
suitable for cement manufacturing.
In Karnataka, limestone is supplied generally
to paper mills and cement plants. However,
limestone of Gulbarga district, commonly known
as 'Shahabad stones', is used as flag stone or
flooring stones.
Limestone from Madhya Pradesh is used in
cement, sugar, paper, steel and lime industries.
In Maharashtra, apart from cement and sugar
industries, limestone is used in Ferro-manganese
Industry as flux and also in Tanning Industry.
Limestone mined in Rajasthan is consumed
in capt ive cement p lants on a la rge sca le .
Limestone of Nagaur district is utilised as feed
for white cement plants as well as in steel plants
as low silica SMS grade flux and in Chemical
Industry. Crystalline limestone of Rajasthan is
widely known as a decorative ornamental stone.
The limestone worked in Bundi district and
Raghunathgarh in Jaipur district is an excellent
flagstone, for use as a paving stone.
The limestone produced in Dehradun-Garhwal
areas of Uttarakhand used to be supplied to
Sugar, Paper, Steel, Glass, Chemical and Cement
Industries in the past.
Limestone in Tamil Nadu is consumed by
various industries like Cement, Steel, Paper,
Foundry, Fertilizer and Chemicals.
Limeshell from Kerala is used mainly in
Chemical, Cement and White cement Industries.
It is also used in the manufacture of polyfibre
and in Tanning industry.
USESLimestone used for industrial purpose falls
under 'major mineral', while the use of limestone
in lime kilns and for building purposes comes
under 'minor mineral' as per Mines and Minerals
(Development and Regulation) Act, 1957.
The threshold value of limestone has been
revised by IBM, Notification in 2009, as follows:
(i) For limestone deposits in Chhattisgarh,
Gujarat, Himachal Pradesh, Madhya Pradesh,
Maharashtra, Rajasthan, Uttarakhand & Uttar
Pradesh - CaO - 34% (min), MgO - 4% (max).
(ii) For limestone deposits of Andhra Pradesh,
Jharkhand, Karnataka, Kerala, Odisha & Tamil
Nadu - CaO - 35% (min), MgO - 4% (max), SiO2 -
18% (max) & Alkalies - 0.5% (max).
The principal use of limestone is in the Cement
Industry. Other important uses are as flux in
metallurgical processes; in Glass, Ceramic, Paper,
Textile and Tanning Industries; for manufacture
of calcium carbide, alkali and bleaching powder;
for water purification and sugar refining; in
fertilizer (calcium ammonium nitrate) and as soil
conditioning agent in agriculture; crushed stone
for ballast and filler in concrete and asphalt; as
rectangular slab in lithography. The whiting (chalk
and precipitated limestone) is used as a filler in
rubber, oil cloth, paint, cosmetic, tooth paste, shoe
polish, etc. Limestone is also used in underground
mine dusting to prevent the propogation of
explosions.
Lime is prepared by heating limestone in kilns
up to 1000 OC. The CO2 released is effluxed and
'quicklime' (CaO) formed remains as hard white
lumps. This when slaked with water and mixed
LIMESTONE AND OTHER CALCAREOUS MATERIALS
32-30
with sand, forms mortar or plaster. Commonly, the
commercial lime is prepared as dry hydrated lime
Ca(OH)2 by adding to quicklime just the right
amount of water (18 parts to 56 parts of CaO). The
value of lime for most purposes depends upon its
CaO (or CaO + MgO) content.
The manufacture of metallic calcium is one of
the latest uses of lime. Calcium is used in reducing
organic compounds, desulphurising petroleum,
debismuthising lead production of hard lead
alloys and calcium-silicon alloys, and in the
manufacture of calcium hydride which is further
used as an efficient hydrogen carrier.
Limeshell is used mainly in Chemical and
White cement Industries. It is also used in the
manufacture of polyfibre and in Tanning industry.
Lime kankar is used in Cement Industry.
SPECIFICATIONS
Cement Industry
Limestone containing 45% (min) CaO and
above is usually preferred in the manufacture of
cement. Magnesia, sulphur and phosphorus are
regarded as deleterious elements. Limestone
should have less than 3% magnesium oxide
(MgO), maximum tolerance being 5 percent. The
presence of P as P2O
5 more than 1% slows down
considerably the setting time of Portland Cement.
Indian cement manufacturers prescribed that the
limestone should have CaO 42% (min), Al2O
3 1 to
2%, Fe2O
3 1 to 2%, SiO
2 12 to 16% and MgO 4%
(max). The broad chemical specifications of
cement grade l imestone (r.o.m.) for cement
manufacture suggested by the National Council
for Cement and Building Materials, New Delhi, are
given in Table-24.

Iron & Steel Industry
In Iron & Steel Industry, limestone is used
both in blast furnace and steel melting shop as a
flux after calcining. It is also added as flux in
self-fluxing iron ore sinters. It has two basic
functions in steel making, first to lower the
temperature of melting and second, to form calcium
silicate which comes out as a slag, as it combines
with silica in iron ore.
For use in the blast furnace, the calcium
carbonate (CaCO3) content in limestone should
not be usually less than 90 percent. The combined
SiO2 and Al
2O
3 should not exceed 6% though up
to 11.5% is allowed; MgO should be within 4%
and sulphur and phosphorus as low as possible.
LIMESTONE AND OTHER CALCAREOUS MATERIALS
32-31
In Steel Melting Shop (SMS), insolubles in
limestone should not exceed more than 4 percent.
Good fluxing limestone should naturally be low in
acid constituents like silica, alumina, sulphur and
phosphorus. Limestone should be dense, massive,
preferably fine-grained, compact and non-fritting
on burning.
BIS has prescr ibed specif icat ions for
flux grade limestone for use in steel plants as per
IS : 10345 - 2004 (Second Revision; Reaffirmed
2009).
Glass Industry
Glass Indus t ry requ i res h igh ca lc ium
limestone (94.5% CaCO3) and 97.5% of combined
CaCO3 and MgCO
3. Iron and other colouring
matters are regarded as objectionable and Fe2O
3
should be up to 0.20% (max). For colourless glass,
limestone should contain 98.5% CaCO3 (min), iron
content as Fe2O
3 should not be more than 0.04%;
and for bottle glass, Fe2O
3 up to 0.05% is used.
The BIS specifications (IS : 997 - 1973); First
Amendment, (Reaffirmed Feb.2013) for limestone
for use in Glass Industry are as follows:
Silica as SiO2
2.5%
Total iron (Fe2O
3)
a) Calcite or marble 0.05%
b) Limestone 0.10%
c) Dolomitic limestone or dolomite 0.15%
Lime (as CaO) 53.0%
Total lime and magnesia 54.50%
(as CaO + MgO)
Chemical Industry
The calcium carbide manufacturers generally
prefer lime containing 95% CaO (min) with
limitations of not more than 3% SiO2, not more
than 0.95% phosphorus and other impurities not
exceeding more than 2%. For the manufacture of
bleaching powder also, lime containing 95% and
above CaO is required. Total Fe2O
3 +Al
2O
3+MnO
2
should be less than 2%; MgO should be below
2% and SiO2 less than 1.5%. Bleaching powder is
prepared by absorpt ion of chlor ine by dry
hydrated lime. The hydrated lime should not
contain more than 2% excess water. Iron and
manganese oxides lead to unsuitability of the
product and iron oxides tend to discolour the
b leached mate r ia l . Magnes ia renders the
bleaching powder hygroscopic. Silica and clay
impede solution and settling of bleaching powder.
BIS has prescribed specification for limestone
for use in chemical industry as per IS: 3204:1978
(First revision.Feb,2009).
Sugar Industry
In Sugar Industry, lime is used for clarification
of cane and beet ju ice , v iz , removing the
impurities from the juice and also for precipitating
sugar from impurities. Milk of lime 1% in volume
of cane juice is added to pre-heated juice.
Limestone used in Sugar Industry must be high
in active lime (CaO 80% min), but low in iron,
alumina and silica. Magnesia should be less than
one percent. Excess silica is undesirable because
it separates as a gelatinous precipitate which
covers the sugar crystals and retards their growth
and filteration. Magnesia is objectionable because
magnesium carbonate is soluble in sugar juice.
Presence of iron tends to colour the finished
product.
The BIS spec i f ica t ions o f l imes tone
for chemica l indus t r ies a re fu rn i shed in
Table - 25.
Fertilizer Industry
Limestone is used only as carrier in the
manufacture of calcium ammonium nitrate fertilizer.
For this purpose, l imestone should contain
MgCO3+CaCO
3 85% (min), SiO
2 5% (max) and acid
insolubles 14% (max).
Foundry Industry
The chemical requirements of l imestone
for use in foundries as per BIS specification
(IS : 4140 -1978); has been withdrawn.

INDUSTRY & CONSUMPTION
Ind ia was the second la rges t cement
producing country in the world after China. There
were 182 large cement plants having an installed
capacity of 338.78 million tonnes in 2013-14 in
addition to mini and white cement plants having
estimated capacity of around 6 million tonnes per
annum. The total installed capacity of cement in
2013-14 was thus about 344.78 million tpy against
324.94 million tpy in the preceding year. Besides,
there are three white cement plants having a
total 990,000 tpy capacity. The total production
of cement reached 240.08 million tonnes in
2013-14 compared to 235.11 million tonnes in
the preceding year.
In 2013-14, the total cosumption of limestone
& other calcareous minerals/ materials, as reported
by different industries was 270.52 million tonnes.

FUTURE OUTLOOK
Ind ia has huge resources o f l imes tone
distributed over different parts of the country.
India is comfortably placed in terms of annual
capacity and production of cement. Cement-grade
limestone occurs in all the limestone-bearing
areas , whi le SMS, BF and chemica l -grade
limestones occur in selective areas. Concerted
efforts to locate SMS and BF grade limestone along
with cement- grade limestone are imperative to
meet the growing demand.
As per the Report of the Working Group,
Planning Commission of India, the total limestone
requirement during 12 th Plan (2012-2017) with
growth scenario of cement @ 10%, 11% and 12%
for the respective GDP growth of 8%, 9% and
10% is projected at 3,163 million tonnes, 3,253
mi l l ion tonnes and 3 ,385 mi l l ion tonnes ,
respectively.
