metals and non-metals

1. INTRODUCTION TO
METALLURGY

2.  THE BRANCH OF SCIENCE WHICH
DEALS WITH EXTRACTION OF
METALS REFINING OF METALS AND
THEIR USES IS CALLED
METALLURGY.

3.  METALS WLL PRESENT IN FREE
STATE (OR) NATIVESTATE (OR) IN
COMBINED STATE.
 FREE STATE:- METALS LIKE
GOLD(Au),SILVER(Ag),PLATINUM(Pt)
ARE KEPT IN LOWER PLACE SO THEY
WILL BE IN FREE STATE

4.  COMBINED STATE:-METALS
COMBINE WITH OXYGEN TO FORM
OXIDES AND WITH SULPHURTO
FORM SULPHIDES.
 METALS WHICH ARE IN THE
HIGHER PLACE IN REACTIVITY
SEREIS THEY CAN EASILY REACT
WITH ENVIRONMENT THOSE ARE
HIGHLY REACTING SO THEY MAY
FORM OXIDES NITRITES AND ETC..

5.  METALS WHICH ARE IN MIDDLE OF
REACTIVITY SEREISWILL FORM
SULPHIDES AND OXIDES.

6.  COMBINED STATE
MIDDLE HIGHER
SULPHIDES OXIDES
OXIDES CHLORIDES
NITRITES
HYDROXIDES

7.  MINERALS:-THE ELEMENT OR
COMPOUND WHCH OCCUR
NATURALLY IN THE EARTHS CRUST
ARE CALLED MINERALS.

8.  ORES:-MINERALS THAT CONTAIN
VERY HIGH % OF METAL AND THAT
CAN BE PROFITABILLY EXTRACTED
ARE KNOWN AS ORES.

9.  GANGUE:-THE IMPURITIES
ASSOCIATED WITH THE ORE IS
CALLED AS GANGUE.OR MATRIC.
 IMPURITES PRESENT IN ORE ARE
SAND , SOIL, ETC..

10.  FLUX:- FLUX IS THE CHEMICAL
SUBSTANCE ADDED TO THE ORE TO
REMOVE GANGUE.
 FLUX ARE OF 2 TYPES:-
ACIDIC BASIC
 ACIDIC FLUX IS USED TO CLEAR
BASIC IMPURITIES.
 BASICFLUX IS USED TO CLEAR
ACIDIC IMPURITIES.

11.  SLAG:-IT S FUSIBLE PRODUCT
FORMED WHEN FLUX IS REACTED
WITH GANGUE IS CALLED SLAG.
