6. The world is depended on mineral from needal to
airplane, so the major question is from where the,
The minerals come out so in list of minerals we get
opportunity to explore one off the major mineral
called limestone through our college internship.
We will explore what is limestone its type, uses, and
also discuss limestone identification in field, mining
of limestone and many more.
And also explore Cement plant, and we learn how
cement become, through which processes and try to
understand what ups and downs comes in that
processes

7.  Aim
 The strategy aims to improve mining regulation and take a
more sustainable approach while addressing people’s
concerns who are touched by the industry.
 The goal of the National Mineral Policy 2019 is to create a
more meaningful, implementable, and effective policy that
promotes more openness, better regulation, enforcement, and
balanced society along with economic growth and sustainable
mining practices
 Proposes the creation of an overarching inter-ministerial
organisation under the Ministry of Mines to institutionalise
sustainable mining procedures. The group will also advise the
government on royalty rates, dead rent, and other matters.
 Ensuring environmental sustainability while raising
performance standards is a significant development and
policy concern for the mining industry.

8.  Limestone is a sedimentary rock composed mainly of calcium
carbonate (CaCO3) and magnesium carbonate (MgCO3). The
chief minerals found in limestone
are calcite and aragonite; dolomite is also be present in the
dolomitic limestones
 .
 varieties of limestone most have been deposited in shallow
water. Limestones (e.g., chalk) are formed from the calcareous
skeletons
 of marine organisms.
 Precipitated limestones include oolite, which is composed of
ooliths – spherical bodies formed by the precipitation of
carbonate around a nucleus.

Fossiliferous limestone
Lithographic limestone
Oolite – Sedimentary rock formed from ooids

10.  Coralline limestone
 Coralline Rock is a type of rock formed by the death of
layers of coralline algae. It is visually quite bright like
the algae, and is often desired as aquarium decoration.
Since it is formed from the dead algae, it contains some
nutrients and calcium carbonate which has allowed it to
be used in some building structures.
 Nodular limestone
In sedimentology and geology, a nodule is small, irregularly
rounded knot, mass, or lump of a mineral or mineral
aggregate that typically has a contrasting composition, such
as a pyrite nodule in coal, a chert.
Minerals that typically form nodules include calcite, chert,
apatite (phosphorite), anhydrite, and pyrite Minerals that
typically form nodules include calcite, chert, apatite
(phosphorite), anhydrite, and pyrite

11.  Mining is the process of extracting useful
materials from the earth. Some examples of
substances that are mined include coal, gold, or
iron ore. Iron ore is the material from which the
metal iron is produced. The process of mining
dates back to prehistoric times.
 The primary methods used to extract minerals
from the ground are:
 1 Underground mining.
 2 Surface (open pit) mining.
 3 Placer mining.

15.  The marine Cretaceous sediments derive their name from
the type locality Bagh, situated in the western part of
Narmada valley in Madhya Pradesh.
 The sediments of Bagh Group occur intermittently over a
distance of about 345 kms. From near the Gulf of Cambay
(Gujarat) in the west to Barwaha (Madhya Pradesh) in the
east via areas of Jhabua and Dhar districts.
 These sediments exposed mainly along the edges of the
Deccan lava flows. In Madhya Pradesh, the best exposures
are being found in the valleys of the Maan river .
 Localities of that mine(lat, long, )
 Underlying the spread of the Deccan Trap and fringing its
margine, there are many exposures of these rocks in the
Jobat region of Jhabua district.
 (Lat. 22o33’, Long. 75o11’), baghni river south of Bagh
(Lat. 22o22’, Long. 74o50’) and the sections of the Hathni
and Ankhar rivers near Ali(Lat. 22o16’, Long. 74o24’)

16.  The Deccan Traps flow basalt (65 Ma) is one of the
largest volcanic features on Earth, and crops out
over 500,000 sq. km of the west-central Indian
subcontinent. The trap complex is predominantly
composed of multiple layers of tholeiitic flood
basalt. The thickness varies from more than 2000 m
in the Western Ghats to over 1000 m in eastern part
of the province to less than 100 m in some
 The flood basalt province known as the Deccan
Traps is located on the Deccan Plateau in west-
central India and is one of the largest volcanic
provinces in the world.

21. Geology of the area After the deposition of Gondwanas and
before the
outpouring of Deccan Trap lava flows, the exposed surfaces
of Gondwana rocks and the older Archean metamorphics
were eroded. On the eroded surfaces of these rocks,
some lacustrine and fluviatile sediment deposited.
These the are Lameta Beds. Marine equivalents of the
Lametas
are the Bagh Beds of Narmada valley. Because Bagh and
Lameta
beds occur immediately below the Deccan
Trap flows, they are known as Infratrappeans
In the Manawar area, the Bagh Beds occur as
inliers in the Deccan Trap, by the denudation of
which these beds are exposed. In the area, Bagh
and Lameta beds show the following sequence:

26. A cement is a binder, a chemical substance used for
construction that sets, hardens, and adheres to
other materials to bind them together.
cement, in general, adhesive substances of all kinds, but, in
a narrower sense, the binding materials used
in building and civil engineering construction.
History
Cement
cement as we know it was first developed by Joseph Aspdin, an enterprising
19th-century British
The Egyptians used a cement-like material (containing gypsum) to
make the Great Pyramid in 2600 B.C.
Five states produce nearly 50% of all the cement made in America.
They are (in order): California, Texas, Michigan, Pennsylvania and Missouri.
Cement is a caustic. It can burn skin and eyes, just like acid.

27. There are four stages in the manufacture of portland cement:
(1) crushing and grinding the raw materials,
(2) blending the materials in the correct proportions,
(3) burning the prepared mix in a kiln, and
(4) grinding the burned product, known as “clinker,” together with some
5 percent of gypsum (to control the time of set of the cement

28. *THE BASIC COMPONENT OF CEMENT PRODUCTION PROCESS
Raw materials
Composition
Portland cement consists essentially of compounds of lime (calcium oxide,
CaO)
mixed with silica (silicon dioxide, SiO2) and alumina (aluminum oxide, Al2O3).
The lime is obtained from a calcareous (lime-containing) raw material, and
the
other oxides are derived from an argillaceous (clayey) material. Additional
raw materials such as silica sand, iron oxide (Fe2O3), and bauxite—containing
hydrated aluminum, Al(OH)3—may be used in smallerquantities to get the
desired composition.

29.  Crushing and grinding
 All except soft materials are first crushed,
often in two stages, and then ground, usually
in a rotating, cylindrical ball, or tube mills
containing a charge of steel grinding balls.
This grinding is done wet or dry, depending
on the process in use, but for dry grinding
the raw materials first may need to be dried
in cylindrical, rotary dryers.
Blending
 A first approximation of the
chemical composition required for a
particular cement is obtained by selective
quarrying and control of the raw material fed
to the crushing and grinding plant.
 Burning
The earliest kilns in which cement was burned
in batches were bottle kilns, followed by
chamber kilns and then by continuous shaft
kilns. The shaft kiln in a modernized form is
still used in some countries, but the
dominant means of burning is the rotary
kilien
Sagar cement lim.

30.  The temperature at the firing end ranges from about 1,350 to 1,550 °C
(2,460 to 2,820 °F), depending on
 Grinding
 The clinker and the required amount of gypsum are ground
to a fine powder in horizontal mills similar to those used for
grinding the raw materials. The material may pass straight
through the mill (open-circuit grinding), or coarser material
may be separated from the ground product and returned to
the mill for further grinding (closed-circuit grinding).
Sometimes a small amount of a grinding aid is added to the
feed material. For air-entraining cements (discussed in the
following section) the addition of an air-entraining agent is
similarly made.
 Gypsum plasters
 Gypsum plasters are used for plastering, the manufacture of plaster boards
and slabs, and in one form of floor-surfacing material.
These gypsum cements are mainly produced by heating natural gypsum
(calcium sulfate dihydrate, CaSO4 · 2H2O) and dehydrating it to give calcium
sulfate hemihydrate (CaSO4 · 1/2H2O) or anhydrous (water-free) calcium
sulfate. Gypsum and anhydrite obtained as by-products in chemical
manufacture also are used as raw materials.


31. 1-Fineness -measuring the particle size distribution by the
rate of sedimentation of the cement in kerosene or by
elutriation (separation) in an airstream.
2-Soundness-This property of soundness is tested by
subjecting the set cement to boiling in water or to high-pre
ssure steam. Unsoundness can arise from the presence in the
cement of too much free magnesia or hard-burned free lime.
3-setting time The initial setting time is the interval between
the mixing of the cement with water and the time when the
mix has lost plasticity
4-Strength -The tests that measure the rate at which a
cement develops strength are usually made on
a mortar commonly composed of one part cement to three
parts sand,
Cement testing
Various tests to which cements must conform are laid down in national cement
specifications to control the fineness, soundness, setting time, and strength
of the cement. These tests are described in turn below.

36.  cement, Agent that binds concrete and mortar. Cements
are finely ground powders that, when mixed with water,
set to a hard mass. The cement of 2,000 years ago was a
mixture of ash and lime. Volcanic ash mined near the city
of Puteoli (now Pozzuoli), near Naples, was particularly
rich in essential aluminosilicate minerals, giving rise to
the pozzolana cement of the Roman era.
“May you have fault in life
May you have night like darkness of coal
May you have to do work as hardness of Diamond
May your body feel hotness like lava
But if your dedication is stable like mountain
The days comes true when you rises like a sun of your
darkness”
