  • Myself Sunep Jamir, I’m a B.E. Electronics Engineer. For two years I’ve worked in TCS, Delhi and times I’ve written Mains with Geography Optional subject.
  • In this Revision Lecture series, I’ve be covering the important topics of Geography for Mains General Studies paper-1. There won’t be an ‘organic’ flow in the lecture because I’m only covering selected aspects and unique phenomenon, and moving from one topic to another in a speedy manner.
  • Due to technical limitations, the whiteboard is not captured. But since I’m describing as a draw, it should not bear much problem, so please bear with it.

  1. India is the 2nd largest producer of rare earth metals
    But it lacks the technology to refine them for commercial purposes
    Refining them is expensive and uses toxic acids
    China though is the largest producer of rare earth metals faced a serious crisis when the toxic by products entered yellow river
    So better would be to import them or mine the mineral and send it to japan for processing
    I think a agreement was signed bw japan and india in this regard
    Correct if wrong
