Gold panning

technology Maturity 11-13 Next article →

Gold panning is a traditional form of placer mining. It is a method used to extract gold from placer deposits. These deposits are accumulations of minerals found in environments like river beds. Panning is one of the simplest ways to find gold. It is very popular with geology enthusiasts because it is low cost. The process is also relatively simple to learn.

The mechanism of panning relies on a process called stratification. First, a prospector locates a suitable placer deposit. They scoop alluvial deposits into a pan. The material is then wetted with water. The prospector uses soaking, fingering, and aggressive agitation to loosen the gold from the soil. This agitation causes stratification. During stratification, materials with a low specific gravity rise to the top. Materials with a high specific gravity sink to the bottom. Gold is very dense, so it sinks to the bottom of the sediment. This allows the prospector to wash away lighter materials. What remains in the pan is usually black sand, stones, or dense metal particles.

There are many different types of pans designed for different needs. Most pans have features to trap heavy materials or remove light ones. Some specialized pans are designed for use with mercury. Other designs include screens or sharp corners for breaking ice. Some pans are even built to work with or without water. Edward Otho Cresap Ord, II, was an Army officer who patented several designs. He owned several mines and created pans for dry or mercury use.

Modern pans come in various materials and sizes. Most pans are measured by their diameter in inches or centimeters. Common sizes today range between 12 and 14 inches. The sides of a pan are usually angled between 30° and 45°. Traditional pans were made of Russia iron or heavy gauge steel. Steel pans are heavier and stronger than plastic ones. Today, many people use high-impact plastic pans. These plastic pans resist rust, acid, and corrosion. Many have moulded riffles, which are ridges, along one side. Prospectors often prefer green or red plastic pans. These colors help the gold and black sand stand out. Some people also use black pans to identify deposits easily.

Different cultures have developed unique tools for finding gold. The batea is a Spanish variant of the gold pan. It is often made of a solid piece of wood or metal. Bateas are larger than standard pans, measuring nearly 20 inches in diameter. They are used in areas with limited water, such as Mexico and South America. In Japan, people use a tool called the yuri-ita. This is a rectangular wooden pan with a concave cross section. It is open at one end and sealed at the other. As the name suggests, it requires a rocking motion to pan the gold.

In Romania, a traditional wooden pan called the șaitroc is used. The name comes from the German words "scheiden" and "Trog." This means to separate or divide in a trough. It is used in Transylvania for panning gold or separating gold from crushed ore.

History shows that people have used these methods for a very long time. The first recorded instances of placer mining come from ancient Rome. Romans used pans and sluices to extract gold from streams and mountainsides. While panning is effective, it has a low productivity rate. It cannot compete with large-scale industrial methods. For example, the Super Pit gold mine in Kalgoorlie, Western Australia, uses large extractors. Because of this, panning has been largely replaced in the commercial market. However, it remains an important part of the assaying process. Assaying is when portions of paydirt are analyzed to find the amount of gold per ton. Panning is also a vital tool for prospecting. It helps people locate parent gold veins. These veins are the original source of most placer deposits.
