Chemical Analysis Section

In this unit, chemical analysis of various minerals and mineral-derived metals and non-metal samples are carried out mainly by adopting the conventional method (Gravimetric/Volumetric method). Required available for said test work

Equipment like E-Balance, Drying Oven, Muffle Furnace, Hotplate, Volumetric glasses, and Titrometry method are used to provide the result of complete analysis to the customer.

 

The following types of geological samples are tested in this unit-

Limestone, Dolomite, Magnesite

Iron ore (Haematite, Magnetite)

Silicate rocks

Copper ore

Granite

 

The instruments used for the conventional analysis of the samples are-

 

Drying Oven:  

 

Sample Drying: To avoid unnecessary moisture, drying is done in the oven at 105°C ± 5°C for an hour

Digital Balance: Analytical Balance with 4 digit numbers (0.0000 g) is designed to measure small mass (0.1 mg) in the milligram range.

 

 

Muffle Furnace: To ignite the sample at the temperature of 1000C in the Muffle Furnace

 

 

 

                                         

Digital Hotplate: To heat the sample up to 250°C and complete the digestion and baking process. 

 

Volumetric Glassware: Pipette 1 to 50 ml, Burette 50 ml, Volumetric flask 250, 500 ml, conical flask 250 ml, beaker 200, 400, 500 ml etc. used for filtration process, titration process, and making solution.

 

Trace Element Analysis Section

This lab is conducting quantitative analysis of heavy elements like Fe, Cu, Au, Pb, Zn, etc. in rock, soil, sediments, etc. That is a supplemental test as well as independent with respect to the conventional analysis.

 

Instruments Available

 

i. AAS SHIMADZU 7000 model

Atomic Absorption Spectrometry to measure heavy trace elements in parts per million (ppm) concentrations.

 

ii. ICP – MS  Agielent  7800 model

Inductive Coupled Plasma Mass Spectrometer for trace elements, including more than 50 elements above Atomic number 12 in parts per billion (ppb) concentrations.

 

iii.XRF Bruker S2 Ranger  

X-ray Fluorescence for major element oxides in percentage.
