Summary(Plain Language Summary, not published)
Field collection and commercial processing of bulk sediment samples for isolating kimberlite (diamond) indicator minerals and other economic heavy minerals using gravity/density separation methods is a standard mineral exploration protocol used by the GSC. Typically this requires the collection of large (30 kg) samples, which in remote locations can be operationally limited due to payload restrictions. Large samples also require additional funding for processing. This study tests the accuracy and precision of a field-portable apparatus to produce a concentrate of heavier mineral fractions. If suitable, use of this apparatus could improve exploration success by reducing the volumes and weight of material needing to be shipped from the field, and increase the volume of material that could be processed where indicator minerals occur in very low abundances, improving potential recovery.
