    In X-Ray Diffraction, x-raysof a known wave length are

    used for examinations.

    Using Braggs law, the

    determination of lattice

    spacing dhklwhich is

    characteristic for any

    crystallographic or

    mineralogical phase, is done

    by obtaining the reflection

    angle, 2hklwith the help of

    diffractometer.

    Used for non-destructive

    chemical analysis of rocks,

    minerals, sediments & fluids.

    It works on x-ray

    spectroscopic principles.

    XRF generally cannot make

    analysis at small spots, so itis typically used for bulk

    analysis.

    Due its low cost of sample

    preparation, stability & ease

    of use, its widely used foranalysis of major & trace

    elements in rocks, minerals

    etc.

    A pot flux analyser is

    specially developed for the

    needs of pot flux analysis &

    bath ratio determination in

    aluminium industries.

    It includes a x-ray

    diffraction system for

    analysis of typical bathphases & x-ray fluorescence

    channel for determination of

    total calcium contents in

    bath samples.

    It is very cost effective as itdoes not requires external

    water chillers.

    It is used to determine

    the concentration of aspecific metal element

    in a sample.

    This spectroscopy can

    be used to analyze over

    70 different metals in a

    solution.

    It uses Lambert-Beer

    law for its calculations.

    It images the sample surface by

    scanning it with a high-energy beam

    of electrons.It produces signals which give

    information about the sample

    surface topography, constitution &

    other properties such as electrical

    conductivity.

    The types of signals produced by

    SEM include secondary electrons,

    back-scattered electrons(BSE),

    characteristic x-rays,

    light(cathodoluminescence),

    specimen current & transmitted

    electrons.

    Due to very narrow electron beam,SEM micrographs have large depth

    of field yielding a characteristic 3-d

    appearance useful for

    understanding the surface structure

    of a sample

    These microscopes are commonly

    known as ore microscopes since

    they view thick polished specimensof rocks and minerals.

    The rock ore is polished and only

    the top surface is viewed. Since the

    ore is thick, it is opaque and no

    light is transmitted through it.

    The ore microscope applies

    incident polarized light to thespecimens surface which is

    reflected back into the microscope

    objective to be viewed in the

    eyepieces.

    Most polarizing microscopes

    produce only transmitted polarized

    light. This means they provide light

    from the bottom and it transmits

    through the thin section of

    specimen on a microscope slide.

    It is a universal sheet metal

    testing machine for research,

    development & in process

    testing.

    The special feature of this

    testing machine is the increased

    drawing speed of the drawing

    punch which can be adjusted inan infinitely variable manner &

    independent of load up to

    3000mm/min.

    This is achieved by using a

    separate oil circuit fed by pump

    with high volumetricdisplacement.

    An useful microscope with

    illumination is also used to

    make the detection of cracks

    much easier.Manual sheet testing machine, 30kN

    Instron 5569 mechanical tester

    is capable of a wide variety of

    mechanical testing methods.The machine evaluates the

    mechanical properties of the

    metals using tension,

    compression, flexure, fatigue,

    impact, torsion & hardness

    tests.

    The data collection & analysis

    including instrumental control

    are performed by Instrons

    Merlin software.

    Process of reducing thickness or

    changing cross

    section by compressive forcesapplied through a

    set of rolls.

    Continuous casting into semi-

    finished products

    has economic benefits

    Integrated mills are large,expensive facilities

    with complete sequence of rolling

    and forming

    activities. Mini mills utilize scrap

    metal.
