I wasnt done testing yet. The gold in the crushed ore was rather large and chunky, and there was virtually no black sand in it. I had expected the sluice to do well with the ore. A more real-world test would be to see how it handles fine gold mixed with black sand, like what it would ...

    Gold ores usually contain a mixture of coarse and fine-grained gold particles. As fine gold can be lost to the tailings when the pulp flow speed is high, it is always beneficial to have multiple-stage sluices. As most of the gold is recovered in the first meter of a sluice, a way to increase the gold recovery is by using a zigzag arrangement.Gold ores usually contain a mixture of coarse and fine-grained gold particles.
