Beyond the Gold Pan: Mastering Sluices and Centrifugal Gold Recovery

A pan may show gold in a sample. Would a sluice or centrifugal concentrator recover more from that particular material? Beyond the Gold Pan follows a defined feed stream through both kinds of equipment and the tailings left behind.

Learn how classification, water, feed rate, cleanup, and sampling affect a fair comparison; measure losses without counting the same gold twice; and question a vendor's recovery claim before buying machinery.

Trial worksheets keep sample labels, results, permissions, and costs together so the next step is based on evidence rather than excitement.

• Define the feed stream before comparing a pan, sluice, and centrifugal concentrator.
• Measure classification, water, feed rate, cleanup, and tailings without double counting recovered gold.
• Use trial sheets to record samples, permissions, results, and equipment costs.

Let a controlled field test guide the next purchase.
