Testing 1100 GPH Bilge Pump for Gold Mining. What is the real world flow rate?
Вставка
- Опубліковано 4 лип 2024
- I wanted to see how much water was actually flowing through my six inch wide cleanup sluice. I compared the actual real world flow rates with some sluice studies to see how to setup my sluice box for fine gold recovery.

Excellent information. You won't make your millions off this but this will be key information for anyone looking for this specific stuff
Glad you found it useful!
Kyle, this was like attending a class on my favorite topic by an excellent teacher. Great stuff! I have read the PopAndSon Sluice study PDF a few times, was interesting to hear someone bring it to life. Note that they use multiple (2-3) sizes of expanded metal - to catch coarser gold (which isn't an issue in your part of Alberta). I hereby issue you a challenge. A Dollar Store plastic boot tray is ~12 inches wide. Try running it as a sluice with black ribbed carpet from the dollar store, with *no expanded metal* on top. The ribs function like expanded metal, and the spaces between are like drop riffles. The boot tray also makes a good extension. Just place it on the ground at a slight angle, and have your highbanker discharge into a catch pan at the top of the boot tray with the ribbed carpet. I have run a highbanker with this exact setup on The Fraser River and caught a ton of flour gold in a heavy black sand area. Whether you make a video about this or not, I dare you to try it yourself and see the capture rate. Won't cost more that $10, and the boot tray is extremely lightweight and compact. As a bonus, you can vary the sluice width on the boot trayusing simple wooden garden stakes. To get even crazier, you could angle the garden stakes to have the sluice width gradually taper outwards. Just some ideas I have tested on and off over the past 4 years. If you do try the dollar store boot tray sluice with ribbed carpet, don't be shy about the angle as you don't want sandbars forming as that is a gold robber. Cheers!
Source - PopAndSon sluice documentation "So through trail and error, we have developed the Popandson Sluice for fine gold recovery, comprised of a series of different sizes of raised expanded metal over Nomad
miner’s moss in a simple and inexpensive gravity sluice. Testing 1,2 shows recoveries of
+95% of gold from 100 to 200 mesh, and +85% of gold from 200-325 mesh at small
scale “production rates”. Nuggets to 5/16” are also captured."
Dan, I'd actually love to do a full mat comparison video one of these days, but it just takes a lot of time to do the testing properly the way I'd like to test everything. I do have a few ideas already of things to test out, and will add the dollar stove matting to the running. I haven't actually gone looking for ribbed matting at the dollar store yet, if you could, I'd love to see a picture of what you had success too. Email me a picture from your cellphone if you get a chance and I'll try to hunt some down for when I do the test. :)
I thought I would be spending most of next fall experimenting but you just answered most of my questions!
Keep it up the good work!
Glad I could help!
Good information. Thank you!
That 1100 GPH is the perfect flow rate, or maybe just a little too fast, to run my drop riffle sluice (6 1/4" wide x 28"). I get great exchange at a slight angle, and capture the 100 mesh gold.
Yeah it works out perfect even if it happens to be rated a little ambitiously!
I am going to call you professor Upmost from now on 😅😅. Puppet and I can’t sleep tonight, nothing like listening to your lectures to knock me out cold!
Good night.
Great video thanks for the lesson
You are most welcome!
THANK YOU AS I HAVE SO MANY PUMPS, VALVES, HOSE DIAMETERS, CLAMPS ,NO CLAMPS, PRESS FIT ,COMPRESSION FIT, 1INCH TO HALF INCH TO 1/4 INCH, SILICONE ,PLUMBERS PUTTY, DREAM MAP ,GOLD HOG MATS ,
1100, GPH, 800 GPH, 600 ,FISH TANK PUMP ON YOUR MILLER TABLE .
THANKS BRO
It sure can get complicated quickly!
Looks awesome 👍 good job nice and neat too 👍
Thanks!
Wow! Thanks mazuj2! The timing of this is amazing as I was just filming a new years video in the garage expressing my gratitude for all the support I've received so far this year. Warms my heart my freind!!
If your going to run a 5 inch sluice just use the 6 inch with 2 spacers down each side to choke it down. That way you have a normal size setup for matting and the like without waste. The same machine can them be stripped down to just v mat in the field and back to the 6 inch configuration for slow cons cleanup before leaving the river.
That's an excellent idea!
Good video. Now to do a prototype build and test in the real world . If you have 90%+ recovery rate you are doing not to bad . Yardage rates will vary as per person and gravel type . If your recovery will catch flour, flake, and nugget at a high percentage you will have a good high banker. People will knock down your door to purchase such an animal. if it can be broke down and packaged for ease of hauling they will kick your door down to get the sluice that is a full meal deal . eliminating bottle necks to production is a must . Doing a bucket brigade and pre-classifying material is a bottle neck . Sugar scooping that classified material another , having to clean off the classifying screen or grizzly bars is another . Scouring and loss of gold when not shoveling with water running . By the look of your latest double decker sluice you are very close . A yard of material is about 45 5gallon buckets . I think Kyle will have a good turn key product when he makes it available.
Thanks Bart! I'll be working towards a full scale Alberta production highbanker that's checks as many boxes as possible and makes all the right comprises to still be light... in time! What do you think of a video series discussing all my design considerations as I work towards a production model? Could be helpful to me to get feedback along the way.
@@UtmostOutdoors Yes good idea brainstorming
Great informative video ! Your always so comfortable on camera, I have to edit the crap out of my videos to make a sentence lol.
Thanks! The secret is sometimes to film the same thing 3 times over after having spent the last two days coming up with what to say! lol... Although sometimes I can just spout out info naturally if it's mining related!
@@UtmostOutdoors lol this comment is funny 🤣🤣🤣
As with you I build my own stuff and built an 8 in wide 48 in long and started with a 1100 pump didn't like the flow and went to a 2000
Dint like that and put a second 2000 knowing I wasn't getting full 4000 per but liked the flow at this and burned one pump got a 3700 and really like what I have going now on Michigan fly poop -100 mesh and smaller
Check out Poling’s and Clarkson’s studies as well. Sluice width is the largest determining factor as to amount of material and hour. Ideal slurry density is 12% solids, or 1 gal of material per 8 gal water.
I was always impressed with the yardage they were putting through their sluices in these big commercial studies. If I recall correctly they also discusses scouring action while running empty. I found that the pop'n'son sluice style runs far less in terms of yards per GPH and sluice width, but does better with scouring when run empty. This is a major consideration for hand fed shovel in operations, as there is always unplanned down time. I love that there are some scientific studies on this subject, as otherwise so much of it just seems subjective. Let me know of any other studies you are aware of and I'd happily read up.
@@UtmostOutdoors I think a major weakness that most people don’t consider is the effect of surging, rapidly changing water densities by dumping solids into the water flow. It rapidly slows down and speeds up over the riffles which is known to knock gold loose as well as pack the riffles full. Use of a hopper to ensure a constant and consistent flow rate should be more widely used.
Excellent point!
Okay cool... I like what you're doing here
Thanks Paul!
You seem like a busy guy. But was wondering if you would want to take on a new project? I came up with a new concept for a new piece of equipment. Before I ask for help, I was wondering if you were interested?
Since I filmed this video in my garage I have moved to Australia and have a fair bit on my plate right now, but it never hurts to ask!
If you do what I do , where I do it and with what I do it with you will get the same results.
But the world is not the same all over , and a one size fits all does not work here.
I have tried and have found trial and error in the field is the best test.
Like @bart bley commented , eliminating bottlenecks is where efficiency should be directed.
I agree! I think there are lot of easy way to loose gold with the wrong mats, but there is SO SOOO much more to it than that. So long as you're somewhere over the 90% mark, you can safely focus on everything else.
@@UtmostOutdoors Just make sure you are travelling towards what it is you are aiming at.
It is so easy to get distracted off that path.
