Panning in mining is a method of recovering valuable minerals and other materials from the earth by retrieving them with a metal pan. This is typically done by using a hand-held device with a horizontal metal surface.
Panning is used by prospectors to search for gold nuggets and other forms of precious minerals and metals in the streams, rivers and sands of the Earth’s crust. The process can also extract gems such in rubies, sapphires, emeralds, and more. It is particularly popular in areas where the land has been eroded or heavily impacted by mining activity, such as abandoned gold mines.
How Does Panning in Mining Work
The method is very simple – a prospector simply walks along the stream bed and collects the pebbles and other debris that they find in their pans. Once they have enough materials in the pan, they swirl it vigorously to separate the various materials from one another. Any material that floats to the top is considered to be worthless and discarded. Anything, that sinks to the bottom is considered to be valuable and can be collected and used for sale or trade.
The panning in mining process is often used in combination with other methods of mining and prospecting to determine the exact locations of valuable minerals and precious metals. For example, gold deposits can be often detected simply by looking for gold particles in gravel and sand that have been retrieved by the panning process.
While this method was once extremely popular among miners and prospectors around the world, it has largely been replaced by more advanced and modern techniques in recent years. It is now almost exclusively by people who are attempting to mine for gold in rivers and streams that have likely already been mined in the past.

The pans used for panning in mining can be made a variety of materials, including wood, plastic, and metal. According to Wikipedia, early gold mining pans were made of copper alloys, but today they are often made of stainless steel or plastic. They can also be made from a number of different designs depending on the needs of the user. They can range from small, hand-held pans that are carried in one hand to large pans that are made to hang over the sides of boats so that they can be dragged across the water to collect larger quantities of gold-bearing debris.
Once a prospector has collected enough material from the riverbed of the stream to perform their assay, they must clean the material to remove any rock and dirt that may be hiding within it. This is typically done by swirling the material in a pan filled with clean water for several minutes in order to remove any dirt or debris.
The technique involved in modern forms of panning is very similar to that of primitive forms of panning, with the only major difference being that it is dine using advanced equipment.
Brief History of Gold Panning in Mining
Since the discovery of gold in California in 1848, many hopeful prospectors has attempted to locate new sources of gold throughout the western united states. One of the primary tools used by these prospectors to locate potential gold sources was the panning technique. While many claim this technique was invented by an early emperor in the 3rd century BC, others argue that Its origins can be traced back even further to ancient Mesopotamia. What is certain is that this technique has been used by many cultures throughout the world throughout history to recover precious metals from rivers and streams. Keep reading here.
