Black Sand Processing: 3 Methods to Get Every Speck of Gold

# Black Sand Processing: 3 Methods to Get Every Speck of Gold

You've run your sluice all day, done your cleanup, and now you're staring at a jar of black sand. The gold is in there—trust me. Let me show you how to get it out.

Why Black Sand Traps Gold

Black sand is mostly magnetite and hematite—heavy iron minerals that concentrate right alongside gold. The problem? That fine gold you can't see is hiding in there, sometimes 10x more than what's visible.

Method 1: Magnet Separation

What You Need: Strong rare earth magnet, plastic bag, pan

This is step one, always. Put your magnet in a plastic bag and drag it through the dried concentrates. The bag lets you release the magnetite without it sticking to your magnet.

Pro Tip: Do this 3-4 times. You'll be surprised how much magnetite was left behind.

Method 2: Blue Bowl Concentrator

What You Need: Blue bowl, water supply, catch bucket

The blue bowl is my go-to for final processing. The swirling water creates a separation zone that lets gold sink while lighter materials wash away.

Setup Tips:

• Slow water flow—barely visible movement
• Feed tiny amounts at a time
• Let it run 30 seconds between feeds

Jake's Results: I pull 95%+ of fine gold from black sand with this method.

Method 3: Gold Wheel (Spiral Wheel)

What You Need: Spiral wheel concentrator, water recirculation

For processing larger volumes of black sand, nothing beats a gold wheel. The spiral grooves catch gold as material washes up and out.

My Processing Routine

1. Dry the concentrates - Sun or low oven heat

2. Magnet separation - Remove all magnetite

3. Pan down - Remove obvious lighter materials

4. Blue bowl - Final gold separation

5. Final pan - Pick out every last piece

Don't Throw Away Those Tailings!

I keep all my black sand tailings in a 5-gallon bucket. Once a year, I run them through the process again. You'd be amazed what I find.

Jake's black sand processing setup has recovered gold down to 400 mesh—stuff you need a loupe to see.
