answ2. Simple visual inspection is always the first method.
For a tiny sample, a few mg of pure material, x-ray diffraction XRD.
If a small sample, (<1gm) x-ray fluorescence XRF in an electron microscope.
A larger sample <100 gm) x-ray fluorescence using a powder sample.
The above methods assume easy access to the equipments.
Thin section microscopy is a simple technique, but takes some time in sample preparation.
The determination would start with the visual inspection of the hand sample.
You will know what the origin of the rock is, and that gives clues to the cohort of minerals expected.
This would be followed by grinding the rock to sort out the particular minerals you are interested in.
by observing it,we properties of different minerals,so by observing it we are able to know which mineral is which
orderly arrngement of atoms, definite chemical compisition with an inorganic solid and it is natrually occurring.
yes Granite is a comman material

They are able to slice the granite into extremely thin layers, observe it under a microscope, and view the amount and type of minerals that are present.
They basically cut or slice the granite apart exposing the "real" minerals inside.
No, granite is not an ore mineral. Ores are the rock form of certain metals.

Granite has feldspar, quartz, biotite.
Granite is an igneous rock with visible mineral crystals.
