Because of heavy sand (black sand) content more than 15%, so adopt the following technology:

Step 1: it is recommended that a water jet centrifuge is used for enrichment, which is expected to enrich about 90% of heavy metals.

Step 2: The tail of the enrichment is added to the secondary enrichment of the sluice box. Since most of the heavy metal has already been enriched by the centrifuge, the sluice box can be cleaned 1-2 times a day.
