gols paning machine

hi every one am here to explaine you what is that:

redges today are more technologically advanced then ever. Since the early 1900s crudely built, steam powered dredges were used in California along rivers. Divers had to use heavy equipment and suits to use this large equipment.

Back in the time of the gold rush gold dredge technology was not utilized and people were forced to pan for gold. As time went on it was discovered that much more gold was in the deeper gravel of riverbeds than the surface gravel of the banks. Today, we have advanced in our technology to where we can now use smaller tools which are easily transported and can get us into places where were not able to be prospected before. This is exciting, since there is still a lot of gold out there to find.

An exciting prospect of today’s dredging equipment is that they are far more efficient than the machines of old. Now people are known to make profitable trips in old mining areas.

There are a few different types of dredges. The most popular of these being the surface dredge.

The Surface Dredge

This type of dredge floats on the surface of the river or stream which you are looking for gold. The silt and other material from the floor is pumped to the surface through a suction hose into a sluice box. The sluice box recovers extremely fine particles of gold. A great advantage of this method is that no diving equipment is needed.

The sluice box is usually rested on a bank or floated on the surface of the water itself.

Today’s sluice boxes now come with multi-stage systems, the most advanced of which are the 3 stage sluices. These are needed because they recover finer grade gold from the material pumped with the dredge.

Most surface dredges today come with a single sluice for the added benefit of being lightweight and compact.

Underwater Dredge

This type of dredge is not as efficient recovering find fold as the surface dredge is, and is therefore less popular. It is cumbersome and hard to handle underwater. It also can not reach the hard to get areas on a riverbank as the surface dredge is. It also has to be completely submerged to work, which is less practical since it can not be used in shallow water. This type of dredge is usually used to find a spot for gold, a surface dredge is then used to efficiently recover the gold.
