Conflict issues include choppy seas, poor underwater visibility, inconsistent fuel delivery, personnel issues, mining location rights, sufficient paydirt discovery, diver safety, and ocean-damaging equipment failures.
Heavier minerals, principally gold and fine-grained black sands (various iron minerals) are separated from the paydirt and reconcentrated by this means.

The bandits, thinking the gold dust is just worthless sand used to make the bundles of skins they were hidden in seem heavier, scatter the paydirt.
