Facilities at Laboratory


  • Sample preparation for analysis is important task in all aspects

  • Received sample is broken in small particles of approx. 1 – 10 mm by hammers manually.

  • Size reduced sample gets crushed and ground manually for 75 – 100 mess size.

  • Ground sample further processed in planetary mill up to 200 mess achieved


  • X-ray fluorescence (XRF) spectrometry is a rapid, quantitative multi-element technique that provides excellent accuracy and unparalleled long-term precision.

  • XRF applications now range from cost-effective stand-alone monitoring to high-performance; multi-element analysis that gives an insight into complex processes, this robust technique is being used for monitoring, process control, quality assurance, compliance and research.

  • By XRF following 26 elements will be analyzed within 20 minutes.


  • Coal And Lignite Analysis.

  • Proximate analysis: It includes determination of Moisture, Ash, Volatile Matter, Calorific value and Fix Carbon.

  • Different forms of Sulphur: It includes Total Sulphur, Sulphate Sulphur, Pyretic Sulphur and Organic Sulphur by difference.

  • Ash analysis: Chemical analysis of Ash.


  • Wet Chemical Analysis

  • Broad Experience and well trained staff makes Laboratory well efficient and referral for wet chemical analysis of minerals.

  • This includes conventional analysis techniques for determination of major elements SiO2 , Al2O3 , CaO , MgO , Fe2O3 , MnO , P2O5 , SO3 , TiO2 , R2O3 , Na2O, K2O, LOI etc.


  • In clays determination of physical properties are more important.    

  • Following facilities are available.

    • Recovery: recovery by means of washing is carried out in levigation plant.

    • In china clay, fire clay and plastic clay

      • Colour and visual examination

      • Oil absorption

      • Exchangeable calcium iron

      • Greet content


  • Megascopic examinations of samples are carried out for its colour, grainsize, structure, texture, reaction with certain chemicals.
  • Thin section study is carried out under latest Polarizing Microscopic to identify the mineral assemblages of rocks, alteration of minerals and derived exact nomenclature of the sample.

  • Besides these model analysis, specific gravity, cutting and polishing characters and compressive strength are also studied in the Petrology Laboratory.
