    Gravity separation relies on density differences to separate desired materials from host rock. Devices used include gold pans, sluices, shaking tables, and jigs. Gravity separation is used at most placer mines and at some lode or vein deposits.4 Amalgamation Fine gold in placer deposits is often not separable from the ore minerals by density alone.

  • Placer Gold vs. Lode Gold (and how to find it!)

    However, mining for lode gold has many more challenges that mining for placer gold. Placer gold mining is much easier. The gold is already separated from the rock, and gravity has concentrated the gold into creeks and rivers where it is more easily accessible.
