All concentrating methods depend on this principle, except for the use of mercury but that's not used in large-scale placer mining. The Sluice Box. In North America, the sluice is the most common concentrator on commercial placer gold wash plants. The sluice box was developed during the California gold rush around in 1849.
Placer gold is not distributed evenly, instead, it collects in certain parts of a stream while other parts have little to no gold. The density difference between gold, water, and other minerals is a key component of placer prospecting. Since gold is very dense it takes a lot of energy to move it, when the water loses energy the gold will stay put.

The mercury mixing shaker, also known as mercury amalgamation shaker, gold panning shaker, placer gold separation shaker, or plastic chute shaker, is a commonly used gold panning equipment in small and medium-sized mines' placer gold separation process. It can be driven by a diesel engine or electric motor.
Alluvial/Placer gold deposits are gold-containing sand-mixed sediments formed after long-term weathering of vein gold deposits.Alluvial gold mining means mining from land surface or river or underground. Gold is in a free state in the sediments, and the difference in specific gravity between sand and gravel is obvious.

This has to do with the centrifugal forces at play. Simply put, the water that travels along the farther bend will have to accelerate to cover the longer distance, whereas the flow along the inside bend is going to slow down …
day, placer gold production comes from the dredge operating at Hammonton, from large placer mines employing the cya-nide process, from byproduct recovery in sand and gravel plants, from small placer mines, and from small dredging op-erations in rivers and streams. With placer mining, recovery of the gold from the ore is
Centrifugal concentrator is a new type of equipment developed in modern times to recover useful minerals in fine mud. For example, centrifuges are often used to extract gold from placer gold mines and rock gold mines. The separation effect of gold ore sludge in the gravity field is poor, and sometimes it is even difficult to separate.
