Geological sample preparation is a vital stage in the analytical process, given the highly variable nature of mineral samples.

The production of a homogeneous sub-sample, representative of the material submitted to the laboratory is the primary purpose of sample preparation. Correct sample preparation allows for representative sub-sampling, which is the foundation of quality analysis. 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. Segregation into high and low grade sample preparation areas and utilisation of techniques such as vacuuming pulveriser vessels and/or quartz washes between samples reduces the potential for contamination. Robotic preparation employing quartz washes is also available at some facilities.Strict adherence to handling, safety and quality protocols ensures quality standards within sample preparation are maintained.

The selection of the actual sample preparation procedures depends on the type and size of the sample, the mineralogy, and the client’s analytical and budgetary requirements. Sample preparation packages are available for commonly used procedures. Please contact our Laboratory Managers to discuss the most suitable options for your requirements.
