4. TYPES :
लोह has been classified into three
varieties

क ल यस
6. ORES :
Hematite -Fe2O3
Magnetite -Fe3O4
Iron pyrite -Fe2 S3,
Copper pyrite - CuFeS2
Siderite -Fe CO3
Iron is chiefly extracted from its oxide ores in
blast furnace

8. क ांतलोह ग्र ह्य लक्षण./tests of genuineness :
Water is boiled in ककांत लोह पकत्र will have odour of
हहांगु
When drop of oil is put on surface of water in the
vessel of ककांतलोह the oil drop does not spread
The milk boiled in ककांतलोह पकत्र,the milk froath
rises up inconical shape and does not spill out
If the vessel of ककांतलोह is applied with the कल्क
of हहांगु, the odour of हहांगु will be lost
If the vessel of ककांतलोह is applied with कल्क of
हिम्ब, the bitterness of हिम्ब will be lost

कृ त्वक पत्रकहण तप्तकहि सप्तवकरां हिषेचयेत् I
(र.र.स)
क्वकथ preparation for लोह शोधि
1P हत्रफलक यवकु ट चूणग (16P) + 8P जल (128P) =
1/4th reduction
शोधि Procedure
हिवकगप 7 times in हत्रफलक क्वकथ Dr.A.P.Shrilata
12. ह्रिह्रवध प क of लोह
शुद्ध लोह is subjected for हत्रहवध पकक to get लोह
भस्म
1. भिुपकक
2. स्थकली पकक
3. पुट पकक
Dr.A.P.Shrilata
13. MAARANA :
Step 1 –भकिुपकक (र.त. 20/22-24)
शोहधत लोहचूणग is immersed in हत्रफलक क्वकथ and
kept under sunlight till the क्वकथ get
evaporated. This procedure is repeated
for 7 times.
Dr.A.P.Shrilata
14. Step 2-स्थकहल पकक (र.त. 20 / 26 – 28)
लोहचूणग which has undergone भकिुपकक is
heated intensely in हत्रफलक क्वकथ till it gets
completely evaporated
Dr.A.P.Shrilata

15. Step 3 --पुटपकक (र.त. 20 / 31 – 39)
⮚ हत्रफलक क्वकथ is used for भकविक
