This PPT was actually done for a class activity. I am a student in 10th CBSE board. This PPT is all about The mineral mica, Its uses, Conservations of minerals and Hazards of mining.

1. NON METALLIC MINERALS.
MICA:
 Mica is widely distributed and occurs
in igneous, metamorphic and sedimentary regimes.
 It has found use in the electronics industry as an
electrical insulator in capacitors and under semiconductor
devices.
 Sheet and block mica are used in the electrical industry as electrical
insulators in electronic equipment, thermal insulation and more.
 Has low power loss factor, di electric strength therefore has an important
role in the electrical industry.
 Found in ChotaNagpur plateau, Jharkhand, Ajmer and Andhra Pradesh.

Hazards of Mining

4. CONSERVATION OF MINERALS.
WHY CONSERVATION?
 Minerals are the adequate products. Their
presence is limited. Conservation of mineral
resources is very important for future use. If their
use is at the same rate we will run short of this
resources in no time resulting in energy crisis.
Their use must be balanced in ecosystem to avoid
energy crisis.

5. Objectives of mineral Conservation
 To encourage and support use of the lower quality minerals, where appropriate,
in preference of higher quality primary aggregate.
 To support the prior extraction of minerals which would otherwise to be sterilized
by non-mineral development.
 To support the re-use and recycling of the
minerals and their products.

6. Ways to Conserve Minerals
 Use of alternate sources of energy like solar energy,
hydroelectric energy, wind energy etc.
 Walking on a path that leads to sustainable development.
 Using the mineral resources with a greater efficiency.
 Use of renewable sources of energy.
 Avoid over-exploitation of the mineral resources.
 Use of biogas as a fuel for cooking instead
of the non-renewable sources of energy.
 Re-use and recycle the minerals and
their products
 Using Minerals in a planned way.

7. HAZARDS OF MINING
Unfortunately, there's a terrible price to be paid for the
wrenching of these materials from the ground, and payment
has been deferred too long. By one estimate, mining
produces
twice as much hazardous garbage as
all other activities combined, and
too often it's the environment that
suffers.

8. MAJOR HAZARDS OF
MINING
 Inhalation of dust created during drilling operation.
 Noise from machines
 Poorly designed shots can result in misfires early ignition
and flying rock.
 Rock fall or slide
 Failure of hydraulic system.
 Fires (from electric gadgets
and machines)
 Fall of roof and sides
 Electric shock and/or burn.

9.  Harmful gas evolution
The fact that rescue measures cannot reach such mining areas,
increases the hazards during mining.

10.  Harmful gas evolution
The fact that rescue measures cannot reach such mining areas,
increases the hazards during mining.
