Gulch gold. Gulch gold is the coarsest that exists in any part of a river system. If nuggets (pieces of gold weighing more than 0.1g) are present, they will mostly be found in gulches (narrow ravines), provided suitable traps are present, such as irregular bedrock.In gulch alluvium, the vast majority of the gold will be found on, or in crevices within, the bedrock.

Gold mining was rough, physical work. Where alluvial gold was very rich, it could be obtained with a shovel and pan. However, pans were used mainly for prospecting. Simple machines known as cradles (often made from wooden liquor boxes) were rocked back and forth – the heavier gold collecting on matting on the cradle base.
This work provides historical information and examines changes in the methods and equipment used in gold recovery and processing operations.

Alluvial gold, also called sand/soil gold, gravel gold, placer gold, or river gold. Gravity separation is suitable for it. This type of gold ore contains mainly free gold blended with sand/soil.
Alluvial Mining 293 the mining of unconsolidated sand and gravel deposits. Cutter heads of the rotating hollow-bit type sited directly in front of the suction pipe are employed to break up the ground and direct the flow of solids to the pipe, the pipe and the rotary shaft being attached to a rigid ladder which is
noted an increase in gold yield in the class -0.2 mm by 40 %, as well as a decrease in the gold content in dredging tailings. Industrial hydraulic sluice devices (HSD-50, HSD-75), as well as suction dredgers SDD-100, remain quite common, but their share in alluvial gold mining is gradually de-creasing.

A suction gold dredge is basically an underwater vacuum cleaner. Material is transported from underwater to the surface and run through a sluice box to capture the gold. A sluice box works because gold is 15 times heavier than sand and gravel and so is easily trapped by the riffles and carpet in the sluice box.
The rivers flow over gravel, washed, separating and concentrating alluvial gold and heavy metals into specific layers. While mining gold is commonly exploited by mining using explosives and "cyanation," alluvial gold is exploited through gravitational washing and gravity sorting with mechanical, ecological equipment.
