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...
*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*
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.

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...

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 ..
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
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
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?
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 .
rahul gupta No Hematite has more Iron content than Magnetitie investingnews.com/daily/resource-investing/base-metals-investing/iron-investing/types-of-iron-ore-hematite-vs-magnetite/
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
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
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
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

Are yr chem thodi hai geography ki class hai glt video dekh li bhai tune ye
Koderma mines are in Jharkhand.. Not Odisha. Request you to correct.
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).

birmitrapur - odisha
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...!
@Mrunal- Sir, Koderma is in Jharkhand!
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 ..

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
due to washing of coal it's calorific value decreases .
plz correct if i m wrong
*Jai Hind Mam!*

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 you very much madam for a very good lecture.
i like the way u say GUN-tur :P
Jai Hind ma'am 🇮🇳🇮🇳🇮🇳

Copper mining is mainly in Rajasthan and Jharkhand
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?
Ur way of teaching is superb 👌
I very like all video that made by u ma'am 😊

Good Morning..
Result will speak dear 🤗
Rajasthan is rich in building stones like SANDSTONE,GRANITE,MARBLE
specialy for me it's make easy for understanding upsc.....thanks ma'm
Kya a sabhi geography ke lecture Upsc k lye enough hai Ya aur nhi Koch parna hoga
I want to ask a question that how is manganese renewable resources despite aboitic nature?
perhaps ocean nodules?
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?
Mam magnetite contains 70% iron while hematite contains 50-60% iron content
Thanks 👍👍👍
17:04 ** Indian coal has low Sulphur content
Nice class mam
India is the 4th largest producer of Iron ore after Aus, Brazil, and China
thank u ma'am 🙏
Lohardaga is a separate district, Hazaribag is another district
Its not cocking coal. Its actually Coking coal (for making coke), It's a major component in Steel industry.
Thank you so much ma’am!❤️❤️
kodarma is in jharkhand
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
Kodarma is in jharkhand largest producer of mica . Correct it.
Lecture is really very good but there is so much mistakes

Mam koderma jharkhand main odisha main nh
Do we have to memorise each and every places??😶😶
How I thanks mrunal sir for providing this type of video
Kodarma is in jharkhand. pls take care of such details. thanks
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 .
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
investingnews.com/daily/resource-investing/base-metals-investing/iron-investing/types-of-iron-ore-hematite-vs-magnetite/
Awesome!
Mam kodarma isn't in Odisha.....kodarma is in Jharkhand......
And Birmitrapur is in Odisha
Yeah
Kodarma -in Jharkhand
Birmitrapur - in odisha
koderma (largest mika producer in world) jharkhand me hai.udisha me nahi hai......viewer please correct it...because i am from koderma...
Osm
Nice video
Mam actually lohardaga and Hajaribag are the two different districts of Jharkhand .
list of copper rich regions doesn't match with other sources on internet. And JHILIMILI coal reserve is in Chattisgarh not M.P.
magnetite is highest grade iron and not haematite...
Magnetite has more iron content than hematite
Excellent
I'm from koderma, jharkhand.
Nice...
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
I think magnetite has highest iron content
Yes
Yes, u r right
KG Basin means Krishna Godavari Basin , not Cauvrey Godavari...
Good
First revision
Singareni is now in Telangana.
Thanks you mam
kodarma is in jharkhand ... please correct it....
Thanks mam
Koderma is in jharkhand
Full screen pr hota to bahut achha hota
koderma in jharkhand not in odisha
MICA- KODERMA is in Jharkhanda, not Odisha
magnetite contained highest iron
*Jai Hind mam!*

Kodarma the highest Mica Producer is the state of Jharkhand, not in Odisa.
+ASHWANI KUMAR Sahu thanku sir ji
Jai Hind dosto 😎😎😎
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

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
Koderma in jharkhand
Its not pyala its playas lake.
koderma gaya-hazaribagh belt is in jharkhand not orissa
Many information's are confusing
Lots of factual and conceptual mistakes in this lecture.From formation of shield regions to mineral content in ores to location of places.
Your audio sucks. Ugh!!!! Please try to correct this issue.
