Ever thought about learning to pan for gold? Its really not that
hard to do - anyone with a little patience can learn it. Perhaps the
oldest and most widely used gold concentration device is the gold pan -
originally called a "gold dish" by the 49ers. Although pans are
available in various shapes and sizes, the standard American gold pan is
12 to 18 inches in diameter at the top and 2 to 2 1/2, inches in depth,
with the sides sloping at roughly 30 to 45 degrees. They can be
purchased at prospecting stores, rock shops and even some hardware
stores for round $8 to $12.
Gold pans are constructed of metal or plastic and both are used in prospecting for gold, for cleaning gold-bearing concentrates, and rarely, for hand working of rich, isolated deposits. Plastic pans are recommended for most folks, because they have some significant advantages over the older steel types - including the fact that they are lighter, don't rust, nor do they conflict with the use of a magnet. Around the world miners use a wide variety of containers in place of the pan. In South America, prospectors have long used an open wooden bowl called a betea to process the gravels. In Mongolia, prospectors are currently using large plastic tubs. The exact shape of the gold pan device is not all that critical, its point is to allow the operator to shake the gravels so the gold settles downward, and then wash the lighter material off the top. Eventually after all the lighter materials have been removed, only the heavy concentrates will remain in pan, hopefully including gold.
First, fill the pan one-half to three fourths full of ore or concentrate - be sure to leave some space at the top especially if you are a beginning gold panner. Add water to the pan or carefully hold the pan under water and mix and knead the material by hand, carefully breaking up lumps of clay and washing any rocks present. As much as possible, wash the clay out from the pan. Re-fill the pan with water (if not held underwater) and carefully remove rocks and pebbles, checking them before discarding - occasionally you may find a piece of Quartz laced with gold although I will tell you this is a very rare occurrence in most locations. Tilt the pan slightly away from you and shake with a back-and-forth motion from side to side. You have to do it hard enough that the gravel material shakes and moves around. The point of the shaking is to allow heavy materials to settle and work their way downward toward the bottom of the pan. Gold is extremely dense and heavy - it is actually much heavier than lead - and so as you shake the pan it naturally wants to move downward through that sand. As you shake, the heavy materials move down, and this leaves the light materials on top. The tilt of your pan should be such that even when shaking back and forth, material does not shake out the pan.
The next step is to wash the light material now on the top layer of your gravel out of the pan. With a gentle forward and back motion while holding it just below the surface of the water, lift the pan and allow a gentle flow of water to wash the light material over the edge of the pan and out of it. Removal of lighter material is facilitated by gently raising and lowering the lip of the pan in and out of the water. After these lighter materials have been washed off the top (typically you have taken off the top quarter inch of material), you will then repeat the process of shaking the pan from side to side with the same type of motion used originally to help concentrate the materials and move the heaviest of the bottom. After a bit of shaking, when the heavies have settled downward, you repeat the second process of watching the lighter material off the top. You have to repeat because gold will not always work its way right down to the bottom of the pan - sometimes it gets stuck along the way down.
Large pebbles should be periodically removed by hand as they come to the top or are revealed during the removal of the light materials. As you continue to repeat these steps, the tilt on the pan will slightly increase. Keep on repeating this two-step process of shaking down and then washing off the lighter material and occasionally picking out the pebbles until you've reduced your material down to a couple of tablespoons full, when only the heaviest material remains. Any gold that is present may be observed by gently swirling the concentrate into a crescent in the bottom rim of the pan. Coarse nuggets are removed by hand, while finer grained gold may be carefully picked out with tweezers or all the black sands may be saved for further processing later. If you have a magnet, and a plastic pan, you can use the magnet to pull some of the black sand out of your concentrates
