Geological Material Screening
The elemental and mass distribution of the different size fractions can be determined by screening unprocessed geological samples. Alternatively, crush or grind goods may be screened to determine the pulverisation process’ effectiveness.
Screening may also be used to see whether a particular analysis is held or hosted preferentially in one or more scale fractions. This gives you more detail about the minerals in your sample. The screen fire assay technique for gold, for example, will provide information on the size and distribution of the gold particles present, and will provide a more reliable measure of the gold present by weighted average, minimising the nugget effect.
To meet customers’ sample screening needs, Sanray Total Quality Assurance laboratory sites usually have a variety of screens with different mesh sizes.
