MINERALS

Spectro has a vast experience in the Testing of Limestone for prospecting, Cement, Minerals, Ores, Metals and Alloys.

We have all the techniques to undertake the analysis ie by Wet Methods, AAS, ICP, XRF, OES. Recently we have added another XRF compact WDX having 200W.

Our Lab is NABL accredited for ISO-17025, Certified for ISO9001:2000 and ISO -14001. Spectro has been dealing with Cement Industry, Cement Consultants, State Mineral Development Departments, Geological Survey of India, Cement Manufacturers of Middle East, Africa, Iraq, Srilanka, Bhutan, Bangla Desh,South America ,Jordan ,Ethiopia on regular basis. We offer inspection, analytical testing, and advisory services to the Minerals, Exploration, Ore and Mining industries.

We also do the sample preparation which is generally, the production of a fine dry pulp that once sub sampled is sufficiently representative of the material submitted to the laboratory for the analytes of interest. The sample preparation is also critical for the liberation of elements of interest for representative sub-sampling, in order to facilitate decomposition techniques, and to reduce particle size effects in techniques such as XRF.

Mineral Sample Decomposition:

One of the first considerations in choosing an exploration method is the decomposition technique to be employed. Sample decomposition techniques include acid digestion and fusions, as follows:

  • Aqua Regia Digestion
  • Single and Multi-Acid Digestions
  • Sodium Peroxide Fusion and Lithium Metaborate Fusion
Testing Instrumentation:

The most commonly used instruments are ICP, ICPMS, AAS and XRF.

ICP and ICPMS are widely used because of their convenient, virtually simultaneous multi-element capabilities.

AAS is generally used where single element work or a small number of elements are required.

XRF pressed powder is routinely used for trace element analysis in exploration samples while XRF fused bead is applied to major element analysis.

Spectro has a range of proven analyses test methods for different ore types to enable accurate percentage level determinations. These include classical wet chemistry techniques through to techniques utilising the latest in analytical instrumentation
