Panning is the simplest way to find gold. Swirl a mixture of water and dirt, and the heavier nuggets will sink to the bottom of the pan. The gold will rush downstream, so make sure you catch it before your rivals do! 4. Tools of the trade The best prospectors can wash around 50 pans a day and also use knives and shovels to dig on dry land.

Step #7 - Processing (on-site) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing. Step #8 - Refining (off-site)

This rudimentary piece of mineral processing equipment uses pulses of water to suspend the particles in water. As the pulses dissipate, the particles settle in the bottom of the jig. Particles with a higher specific gravity (like gold) settle faster than those with a lower specific gravity, effectively separating the gold so it can be collected.

The mineshafts and drifts were then "mucked out" and the gold-bearing ore was transported to the surface for processing. To access the gold, the ore had to be crushed. The first crushing equipment was the Mexican arrastra, a device that ground the ore between two stone slabs rotated by a mule or humans.

Successful gold mining is generally done in two steps: First is sampling or prospecting, and then, production. While some gold-bearing creeks and rivers tend to have gold values dispersed throughout their entire streambeds, there is generally not enough gold to make a small-scale mining operation payoff very well.

Get priceGold panning is a simple process. Once a suitable placer deposit is located, some alluvial deposits are scooped into a pan, where they are then wetted and loosed from attached soils by soaking, fingering and aggressive agitation in water. This is called stratification; which helps dense materials, like gold, sink to the bottom of the pan.

Then work the water up to 1/2 inch down. I'm thinking that if you're getting 100- or finer gold, don't go above 1/2 inch down from the top. Coarser material can have more material put in the bowl. 100-, only about a rounded tablespoon full. Hope this all helps.
