River Aspects: One design component I use within my gold catchers: Waterfalls

This is a continuation of blog series: “Alluvial Gold River Characteristics” I use for my gold capture designs.

1. Waterfalls are drops:

Here are photos of a few famous waterfall drops created by Mother Nature from Wiki link: https://en.wikipedia.org/wiki/Waterfall

She has created an infinite variety:

I have many drops in my GoldHarvester machines

List & photos of waterfalls by type from all over the world:

https://en.wikipedia.org/wiki/List_of_waterfalls_by_type

  • Plunge: Water descends vertically, losing contact with the bedrock surface.[1]
  • Horsetail: Descending water maintains some contact with bedrock.[1]
  • Cataract: A large, powerful waterfall.[1]
  • Multi-step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool.[1]
  • Block: Water descends from a relatively wide stream or river.[1][2]
  • Cascade: Water descends a series of rock steps.[1][2]
  • Segmented: Distinctly separate flows of water form as it descends.[1]
  • Tiered: Water drops in a series of distinct steps or falls.[1]
  • Punchbowl: Water descends in a constricted form and then spreads out in a wider pool.[1]
  • Fan: Water spreads horizontally as it descends while remaining in contact with bedrock.[1]

Note: I incorporate different aspects of these waterfall drops within my GoldHarvester machines.

Design ideas I created, use and build into my Gold capture machines:  

  1. Waterfalls are drops, big drops, big drop riffles created by nature
  2. The water sources feeding the flow upstream of the waterfall are like the mixing hopper on my GoldHarvester machines.
  3. Rain events, especially big rain events are constantly changing the volume & velocity of water flowing over the waterfall, carrying with it all the erosion material including gold of course, if it’s in the river basin system downstream with it.
  4. So pumping up the water volumes in my mixing chamber hopper is really quite natural to material fed into it and creates unbelievable gold production from a small contained area that is pump fed with at least 60t/hr of water for my 10T/hr to 30t/hr line of GoldHarvester machines
  5. I’m not afraid of water volume; I use it to my advantage. The more water the more production, the opposite of most machines on the market today
  6. The Plungepool (water pool with trap formed below it) or contact area (bedrock, rocks…..etc) is a vertical crash plate where tremendous forces collide and distort the flow velocity, for a tiny moment in time to zero velocity, like snapshots in a movie film. All gold at this point drops no matter what the water volume is feeding it. See photo above.
  7. In my header box sections I have several different low pressure zones being created at once that drops all size gold including fine, flat and flake gold. These low pressure zones are distortions created by vertical crash plates, wall crash plates, top crash plates, drop riffles, drop ramp riffles and obstructions in the slick plate and flume box gold capturing inserts. And various angular flow directions for maximum gold drop action results.

This is all detailed in my e-book:

Book 1: “Gold Capture Methods for Commercial Production”

Note:

I don’t give these techniques & methods away for free.

  1. Now what’s next to keep the fine gold from flowing away after dispersing? As the velocity of the water increases back to normal you only have my one design choice; you have to trap it in drop riffles and drop ramp riffles of unique designs to keep and hold it. That is the secret you pay for.
  2. To test this out for yourself, take a 20 liter bucket (5 gallons) of water, mix a shovel of fine sand into it with a flat stick, spinning it into a circle rapidly, this creates a cyclone like vortex in middle of the pail. Now pour this out from 15c (6”) to 30c (1 foot) above a shower floor or into a bathtub and watch what happens to the fine sand (sg is 1.5 to 2.0) dispersing. Now think of fine gold, 19 times heavier than water, sticking to the floor like the sand does, then traveling to trapping mechanisms as flow velocity picks up immediately for you to keep.

I have touched on some of the other points I use for designing my GoldHarvester line of gold getting machines, shown below. These river aspects are all intertwined together as one working unit in my gold machines:

  1. Water
  2. Volume
  3. Flow velocity
  4. Change of direction (I’ve never seen a completely straight river!), always!
  5. Change in elevation, to make it flow (Or it would probably be a lake?), always. This is variable with steep or flat grades or both in same river.
  6. Obstacles & Obstructions: (Many: under the surface-rocks/logs/roots….etc, at the surface-brush, foliage, tree branches….etc, at the sidewalls-steep banks, shear rock, trees…..etc, at the banks-sand, rocks, any soil…..etc, in the middle or anywhere`  -sand/cobble bars, trees, roots
  7. Water falls & Dams created by rock reefs especially gold lode vein rock that crosses the river perpendicularly to create a pond and a small waterfall, 1 meter or less with a trapping pool on the downstream side (a natural Hungarian riffle!) Some of the most lucrative rivers I’ve been on have these natural gold traps with jackpots of gold treasures on both sides of the crossing reefs.

Note:

All of the above river aspects create natural distortions of water flow! This can & will create low pressure zones to drop gold!
