BGI Laboratory Testing Services consists of the Physical and Chemical testing on geological raw materials such as soil, rocks, ores and water. The laboratory is adequately equipped with a wide range of modern instrumentation and competent personnel that enables it to produce quality and timely analytical results. (See BGI Laboratory Services and products table).
The Physical Testing Laboratory prepares geochemical samples through drying, crushing, milling and sieving. Primary treatment is also possible for removal of organic matter, calcium carbonate and chlorides. Separation of heavy minerals from the light ones through density liquids is also applicable. Loss on ignition by heat treatment, determination of limits on clays for soil engineering properties and full brick-earth and pottery are also available. Mineralogical determination is another service done through the X-ray Powder Diffraction, petrography, hardness, thermal conductivity, ALPHA spectrometer.
