plastic gold pan for gold mining
Gold pan is the most basic piece of prospecting equipment. It is both the beginning and the end of the gold prospecting process. It is usually used for sampling before you set up a sluice, highbanker, or dredge. The pan is used for the clean up of concentrates that are collected by those larger pieces of mining equipment. It is used to separate gold, platinum, tungsten, tin and rare metal ores. And it is suitable for sand fields, road and bridge projects, mines, construction sites and other sites.
Size: Gold pans come in various sizes from small 10 inch diameter pans up to 18 inch diameter pans.
Color: Blue, black, grey, green, and so on.
Materials: Plastic or Metal
Shape: round, square, hexagonal, triangular, and even a blend of rectangular and round.
Our gold pan can be made of plastic or metal. But the common use of our gold pan is plastic. It is very popular because of its’ light weight and it requires no maintenance since it will never rust. There are many colors for our gold pan, but black and green are recommended. Because they really help make the gold stand out when you are panning. The traditional shape of a gold pan is round. Besides the round shape, we also supply square, hexagonal, triangular, and even a blend of rectangular and round. You can accord your requirement to choose the right shape. Meanwhile there are a widely choose for pan’s size. Such from 10 to 18 inch. Most prospectors favor a 10, 12 or 14 inch gold pan. Because this size of panning plate is comfortable to operate for most people.
The separation principle of gold pans is similar to that of shaking table. It is also based on the specific gravity difference of the ore and the difference of the movement and speed of the minerals in the water when the gold pan is shaking. Due to the periodic shaking and bumping of minerals in the panning pan, the ore is well loosened, so that the ore particles can be stratified according to the specific gravity along the depth of the pan.
When the particle size is the same, the ore particles with large specific gravity are concentrated under the ore layer with small specific gravity. If the particle size is different and the specific gravity is the same, the fine particles are in the lower layer. The coarse particles are in the upper layer, and the very fine heavy particles are concentrated in the lower layer and deposited on the bottom of the plate. Then the light and coarse particles in the upper layer are winnowed out and discarded as tailings.
Advantages and Features
1. It can be used as long as there is water.
2. It can be used as gravity separation test tool in mine operation.
3. It fits for the beginners of gold panning, mineral processing experiment.
4. It is suitable for use in mountainous areas, rivers and streams where electricity and traffic are not convenient.
5. The gold pan is made of tough plastic, which is resistant to falling, wear and easy to carry.
