Guys - for everyone's benefits - here's the corrections:
1. Hematite has indeed the highest iron conc. Details provided are correct
2. Shimoga, chikmanglur, tumkur and Chitradurg - all 4 are in KA - correct as mentioned in the slide
3. KG its Krishna Godavari - Incorrectly mentioned as Kauvery-godavari in lecture
4. Kodarma is in Jharkand - not Odisha - incorrectly mentioned in lecture
Lets' accept the fact that Mrunal and Team is doing a wonderful job for all of us... let's not criticize like some of the immature comments and lets highlight it for everyone's benefits...
That's the spirit brother, thanks for clarifications.
thanks mam
One more correction, Birmitrapur is in odisha as well.
*Nope, Magnetite has higher metallic content than haematite but hematite ore generally contains large concentrations of hematite, magnetite ore generally holds low concentrations of magnetite*
And birmitrapur is't in Madhya Pradesh
The two ores of iron are hematite and magnetite with the chemical formula Fe2O3 and Fe3O4 respectively. To determine which of the compounds has a higher percentage of iron per kilogram first the molar mass of the two compounds has to be determined.Iron has a molar mass of 55.845 g/mole and oxygen has a molar mass of 16 g/mole. The molar mass of Fe2O3 is 159.69 and that of Fe3O4 is 231.535. In hematite the percentage of iron by mass is `111.69/159.69 ~~ 69.9%` , similarly in magnetite the percentage of iron by mass is approximately 72.3%Magnetite has a higher percentage of iron per kilogram as compared to hematite.
Are yr chem thodi hai geography ki class hai glt video dekh li bhai tune ye
there are some information errors in the lectures, kindly rectify them.. for instance- kodarma is in jharkhand not odisha, odisha is the largest manganese producer not jharkhan (as per NCERT), birmitrapur, an limestone producing region is in odisha not in MP etc...
still a great effort by this website.... you have eased my geo preparation and saved my time.
thanks ma'am...
magnetite (Fe3O4, 72.4% Fe), hematite (Fe2O3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH).n(H2O)) or siderite (FeCO3, 48.2% Fe).
singreni coal field[Ramagundam thermal plant], Kotagudam coal field --->both in telangana now
kodarma mines - jharkhand
KG basin - krishna, godavari
jhil mili coalfield - chattisgarh[part of central india coalfields-MP & Chattisgarh]
birmitrapur - odisha
Koderma mines are in Jharkhand.. Not Odisha. Request you to correct.
CBM poicy 1997 is changed,now CBM comes under HELP 2016 polcy with single license for all hydrocarbons.
In 2018 MoOP and NG alotted coal india the right to explore in such manner in its already coal allocated blocks .
Chaturvedi ji thanks
gyan pelne se selection ni hoga
🇮🇳Jai hind mam 🇮🇳🇮🇳🇮🇳

3rd time done 👍👍
🌻Thank you so much🙏🙏🙏
at 14:26, slide says that Kodarma, the largest mine of Mica, is in Odisha, I think it is in Jharkhand (Jharkhan-Bihar border). Pl check...!
The mineral magnetite actually has higher iron content than the mineral hematite. However, while hematite ore generally contains large concentrations of hematite, magnetite ore tends to hold low concentrations of magnetite. As a result, this type of iron ore ore must be concentrated before it can be used to produce steel.
Formula wise Magnetite ha higher percentage of fe but this concept need to be remembered
Mam i like every video you made .many things are included in a single video. I 'am from nepal and no one has made video about metallic and non-metallic minerals of nepal himalaya ...so can you plz do this small effort ..
Ur way of teaching is superb 👌
I very like all video that made by u ma'am 😊
Playa lake not pyala lake
Also, Sub-Anthracite variety is present in J&K , places are Metka , Mahogala, and Karakot.
Nice lectures.
accha, ho gya selection. badi galti nikal rha h.
madam your lecture is really very beneficial
Thank you very much madam for a very good lecture.
@Mrunal- Sir, Koderma is in Jharkhand!
🇮🇳jai hind mam🇮🇳🇮🇳

specialy for me it's make easy for understanding upsc.....thanks ma'm
Hey I would like to clarify ,Kindly correct ur notes guys :
Hametite Chemical formula : Fe203
Magnetite Chemical formula : Fe304
Hence from easy stoichiometry we can easily see ( science student can found / its a very simple maths) Magnetite has Higher content Than Hametite.
Atomic Mass of Fe : 56
Atomic Mass of Oxygen : 16
P.S
Mam I am really greatful for your kind help .
Mam in rajasthan playa lake not pyala lake. Sorry for this comment but i hope it will useful for us. Wonderful way of teaching. And Free of cost. Hats off
Mam orissa is largest manganese producer .
Also the largest copper producer is madya pradesh which is not even in the list
Where can I find this updated information?
MAM, BIRMITRAPUR IS IN ODDISA,SUNDERGARH DISTT.
Mam magnetite contains 70% iron while hematite contains 50-60% iron content
Copper mining is mainly in Rajasthan and Jharkhand
Jai Hind ma'am 🇮🇳🇮🇳🇮🇳
10/06/2020 👍😊
Thanks 👍👍👍
Rajasthan is rich in building stones like SANDSTONE,GRANITE,MARBLE
due to washing of coal it's calorific value decreases .
plz correct if i m wrong
India is the 4th largest producer of Iron ore after Aus, Brazil, and China
i like the way u say GUN-tur :P
Coking coal is found in Dhanbad (Jharia coalfields) thats why the name of the company there is Bharat Coking coal limited (BCCL) under CIL. Please correct this
thank u ma'am 🙏
Thank you so much ma’am!❤️❤️
*JAI HIND MAM!*

Good Morning..
Result will speak dear 🤗
17:04 ** Indian coal has low Sulphur content
Mam there was a question in upsc about Indian coal
1 it has high ash content
2 it has low sulphur
3 it has high ash fusion temp
From options no ans seemed to be correct..... Can u help?
Magnetite iron content- 70%
Hematite iron content -50-60%
No bro it's haematite ore 60 to 70
Magnatite 60 to 65
Source:majid husain 3rd edition , chapter 7.4
Its not cocking coal. Its actually Coking coal (for making coke), It's a major component in Steel industry.
Nice class mam
Awesome!
Lecture is really very good but there is so much mistakes
Lohardaga is a separate district, Hazaribag is another district
Excellent
Do we have to memorise each and every places??😶😶
Mam kodarma isn't in Odisha.....kodarma is in Jharkhand......
And Birmitrapur is in Odisha
Yeah
Kodarma -in Jharkhand
Birmitrapur - in odisha
Mam actually lohardaga and Hajaribag are the two different districts of Jharkhand .
I want to ask a question that how is manganese renewable resources despite aboitic nature?
perhaps ocean nodules?
How I thanks mrunal sir for providing this type of video
Nice...
Kya a sabhi geography ke lecture Upsc k lye enough hai Ya aur nhi Koch parna hoga
Nice video
Kodarma is in jharkhand largest producer of mica . Correct it.
Kodarma is in jharkhand. pls take care of such details. thanks
I think magnetite has highest iron content
Yes
Yes, u r right
Thanks mam
Thanks you mam
Good
Magnetite has more iron content than hematite
kodarma is in jharkhand
list of copper rich regions doesn't match with other sources on internet. And JHILIMILI coal reserve is in Chattisgarh not M.P.
*Jai Hind mam!*
(10/06/2018)🛡️(05:07 am)
Mangnetite has more iron content than that of Hematite.. Isn't it?
rahul gupta of course yaa..hematite has more iron content
rahul gupta No Hematite has more Iron content than Magnetitie

I'm from koderma, jharkhand.
magnetite is highest grade iron and not haematite...
First revision
koderma (largest mika producer in world) jharkhand me hai.udisha me nahi hai......viewer please correct it...because i am from koderma...
Osm
Thanks
Singareni is now in Telangana.
KG Basin means Krishna Godavari Basin , not Cauvrey Godavari...
magnetite contained highest iron
Mica is found in Nawada Bihar not Munger
Bauxite reserve is mostly mined in Lohardaga, Daltonganj belt in Jharkhand
Amarkantak is in Chattisgarh not MP
Copper is also mined in Jhunjhunu dist. of Rajasthan
U must have also heard abt Bombay High in Arabian sea dat is the largest source of Petroleum in India u didn't mention abt it
Kodarma is in Jharkhand not Odisha
Ur information is not definite
Kodarma the highest Mica Producer is the state of Jharkhand, not in Odisa.

not correct information about most minerals largest producers states.... not matching with internet information....dangerous information for exams..guys please double check with books/ internet
Kodarma mines are in Jharkhand and not odisha...
I can't get your lecture
Yes
madam can u give notes for these class please
Koderma in jharkhand
Lots of factual and conceptual mistakes in this lecture.From formation of shield regions to mineral content in ores to location of places.
koderma gaya-hazaribagh belt is in jharkhand not orissa
Its not pyala its playas lake.
Many information's are confusing
shimoga in maharastra
Pramod kumar Nope, its in Karnataka- en.wikipedia.org/wiki/Shimoga_district
