Physical Laboratory

Physical analysis laboratory of MECL is equipped with state-of-the-art instruments  for carrying out ore and mineral analysis. The different instruments and the services offered are as follows : 


  • X-Ray diffraction -

    For unambiguous qualitative and semi-quantative phase analysis of almost all crystalline mineral species.

  • Derivatography -

    For Thermo electrical technique using parameters such as T, DTA, TG and DTG for analysis of clay, bauxite, limestone etc.

  • Emission spectrography -

    For Very rapid technique for fast, qualitative , semi-qualitative and quantitative estimation of most of the minor & trace elements present in ores & minerals.

MECL has well equipped state-of-the-art chemical, petrology and mineralogy laboratories for undertaking various analysis and studies.



The laboratory is engaged in the petrographic and mineragraphic studies of the rock specimens received from various exploration projects spread all over the country.The laboratory has been carrying out petrological studies of gold, copper, lead-zine, bauxite, tin, tungsten, phosphorite and molybdenum ores for various deposits of the country.The laboratory has interacted with M/s. BRGM in Khobna Tungsten and Tosham Tin Projects and also carried out the studies of rocks from Nickel Deposit of Myanmar.Research papers have been published on the finding of the laboratory from time to time.
