Specifications:The surface dredge floats on the surface of the water. The material is pumped to the surface through a suction hose into an efficient sluice box that is capable of recovering extremely fine particles of fine gold. The sluice box can either rest on the bank, or float on the surface of the water. Another advantage of the surface dredge is it can easily be operated with or without diving equipment. Marlex plastic floats are normally preferred as they are rugged and stable in rough water and are extremely lightweight.
Modern dredges are provided with a Single or “multi stage” recovery systems, such as a the new 3 stage sluice. The multi stage sluice boxes are preferred, because they have a greater capacity to recover a finer grade of gold and black sand concentrates that often hold values. Normally, the smaller size dredges from two to three inches in size are equipped with single sluice boxes, as their primary function is portability and compactness.
