GSI gets machines for quick analysis of mineral samples

  • | Friday | 22nd February, 2019

To find out prospective zones, we will collect more samples from this area this year. Pune: The Geological Survey of India (GSI) has acquired an advanced instrument to carry out accurate and speedy analysis of all types of minerals samples, including rare earth minerals, beach sand minerals, etcAccording to the GSI, rare earth minerals (REM) found in India include ilmenite, sillimanite, garnet, zircon, monazite and rutile, collectively called beach sand minerals (BSM). Secondly, they are not useful for all mineral samples. The newly added facility will provide the required boost to the work,” said a senior geologist, who did not wish to be named. Most importantly, it can detect the concentration of each mineral sample quickly.

Pune: The Geological Survey of India (GSI) has acquired an advanced instrument to carry out accurate and speedy analysis of all types of minerals samples, including rare earth minerals, beach sand minerals, etcAccording to the GSI, rare earth minerals (REM) found in India include ilmenite, sillimanite, garnet, zircon, monazite and rutile, collectively called beach sand minerals (BSM). India has about 35% of the world’s total BSM deposits.These minerals have extensive use in various industries including IT, health care, defence production, clean energy systems, among others.“The instrument ‘wavelength dispersive X-ray fluorescent spectrometer’ will boost our analytical capabilities of all minerals samples. Most importantly, it can detect the concentration of each mineral sample quickly. This ability will help us complete our projects and earmark prospective zones of these minerals,” said deputy director general of GSI’s Maharashtra unit Mahadev Powar.The GSI has provided this gadget to Maharashtra, Tamil Nadu, Rajasthan, Orissa and West Bengal recently.The instrument, Powar said, can analyse elements from sodium to uranium in percentage of parts per million (PPM) concentration without using hazardous chemicals in the rock.“The existing methodologies are time consuming. Secondly, they are not useful for all mineral samples. These are among the main reasons behind the delay in completing the undertaken projects,” said a geologist, who did not wish to be named.The Maharashtra unit has undertaken at least five projects of BSM exploration in Sindhudurg and Ratnagiri districts.“The investigation of old samples has revealed that there is some concentration of BSM minerals in these districts. To find out prospective zones, we will collect more samples from this area this year. The newly added facility will provide the required boost to the work,” said a senior geologist, who did not wish to be named.
