Sluice gates are common hydraulic structures for controlling and regulating flow in open channels. This study investigates five models' performance in distinguishing conditions of flow regimes, estimating the discharge coefficient (Cd) and flow rate. Experiments were conducted for different gate openings, flow rates, upstream and …
During sluicing, a layer of dense particles accumulates at the bottom of the channel and is removed intermittently, while heavy particles are washed continuously …

A power sluice or highbanker is basically a sluice box with height and mobility and is motorized. It is mounted on a 4-legged stand that gives the sluice box the correct slope. Instead of being put right in the creek like a hand sluice, an engine with a water pump and some hoses gets the water up from the stream into the sluice or highbanker.
Sluicing is one of the most popular gold-recovery methods, and a sluice box is often a miner's first purchase after a basic gold pan. There are many options to …
to recovery gold at the earliest possible stage in the flowsheet; a principle in flowsheet design that is still valid today [1]. Despite continuing improvements to gravity recovery methods, these methods were still limited by their inability to recover fine gold or gold associated with sulphides.
Even if the density of the gold is just as high, every bit will be tinier and lighter. This makes the gold much more prone to getting grabbed by the water flow and later discharged out of the sluice. With that said, most gold found is fine gold. Only around 2% of the gold mined today is estimated to be gold nuggets, according to some figures.
To locate the right section to pan or sluice for gold: You should find out more about the course of the river. If you notice that the river has been flowing at a slight slope and mainly fast, follow it until it reaches a calmer pool of water. As we have seen, gold is heavier than other materials. Without the necessary velocity of water to push ...

If too much material is introduced into the flow, the water velocity will slow down and cause the sluice to back up and lose gold. It is much better to gradually add smaller amounts of material to the flow. If you are adding material into the sluice using a scoop, avoid adding material like an ice cream scoop because that disrupts the water ...
