SEM Image Comparison of Selected Crushed Mineral

A hand-crushing technique (via mortar and pestle) was used to represent the macroscopic mineral crushing that occurs throughout the taconite mining industry. The results are intended to show how SEM analyses of these crushed standards can be used as a point of reference for comparison to crushed minerals found within the taconite ore and taconite mining by-products of Minnesota's Mesabi Iron

Crushing and Screening for Mineral Processing Success

For example, to generate a 10mm particle, you'll want to feed the crusher particles between 50 and 70mm. However, to minimize fines, design the crushing circuit with a reduction ratio between 31 and 41 at each stage; this could mean an additional stage of crushing, compared to a traditional circuit.

Anomalous trapping of noble gases during sample

Fine-grained mineral samples are commonly analyzed for noble gas composition. Many coarse minerals contain inclusions that require that the samples be crushed and purified before analysis. Other samples are crushed because fine-grained samples may be degassed at lower temperature. And many rocks lack coarse mineral grains entirely. Protin et al.
