[Sticky] READ THIS FIRST - If you have a matting question.
READ ALL and Read CAREFULLY.......
Answer this question...
What is G ÷ W x SG x P x ST = X
We can't answer it either... but it's kind of what happens when people send us an email saying... I have a 10" x 48" sluice what mats should I use?
That simply is not enough data or info for us to offer advice.
It’s kind of like going to the DR and saying…. I’m sick… I need you to write a prescription.
To spec out ANY system or sluice we must determine the exact sluice energy and better understand the slurry running through it.
Things like what type of equipment do you have, the GPH running through it, gold size in your area, etc... are important.
EXAMPLE: I have a Keene Highbanker- 10" wide, 48" long, running a 2" trash pump rated at 8000 gph, but I measured it and the actual gph going through the sluice is 6000 gph. Most of the gold is in the 50 - 100 mesh range.
You don't HAVE to send a video... but we need GOOD spec info to help you.
The BEST THING YOU CAN DO.... is take a 30 second video on your phone or video camera, of you sluice / system running. If we can VISUALLY SEE the energy in your sluice, we can prescribe a matting config MUCH EASIER. Just step back hold the phone up and steady and let us see the water running through the system.
Also, if you are running any specialty "dirt" or slurry, let us know that as well.
We ALWAYS ASSUME that most people are concerned about capturing FINE GOLD.
(We get it.) We deal with it every day. Just make sure you describe any challenges you're facing if they are unique.
COMMERCIAL OPS... This is a MUST HAVE for US.
I will STRONGLY recommend you shoot a 30 second video of your sluice with water running through it. That 30 seconds will answer more questions than you can imagine. You can upload it to youtube, send it via email, or send it via DROPBOX.com which is a free service we also use.
If you can’t get a video… then provide us with detail information. JUST VIDEO the sluice with material or water running through it. That's really what we care about.
1) What type of equipment are you running?
Stream sluice? Highbanker? Dredge? Commercial Op?
Other details can be critical as well.
Example: if a dredge... crash box or flare?
2) Post the water ENERGY info.
Sluice WIDTH and gallons per inch running through the sluice. Just posting your PUMP gph is not often enough.
3) Post any other info that might be helpful. Such as problems that currently exist with your system.
Special material you are running, etc.
Remember… every single sluice in the entire world runs differently. If it’s not a difference in the equipment, then it might be the dirt being run. That is very important as well.
We speck out operations and individual’s and company’s equipment from all around the world 7 days a week. Whether it’s guy running a stream sluice by himself to a large corporate mining op with 20 plants each running 200 yards an hour. The needed info is the same.
Thanks… The Gold Hog Advisory Team
Hello! I'm new to gold mining, so please forgive if I'm ignorant on some things or most likely, lots of things....
I have a really good friend from there and he has a cousin that's been mining for 45 years. So me and my buddy are going to give it a go. Currently his cousin just opened another mine and is running 50 grams a day average. His style of mining is not very modern at all and is losing roughly 50% out the sluice.
Over burden is anywhere from 6' to 12', pay streak is roughly 3' to 6' thick. Some nuggets, most mostly smaller stuff and lots of fines. Gravel has a few larger rocks, some smaller ones, but is mostly made up of pebbles & sand.
Going to be using a 2 pump set up to start. One for pressurized water to blast the gravel with 4 hoses and another to suck it up for the sluice. Pumps are a 6" and both will have 100 hp diesels on them. I am unsure of the gpm.
Typical sluice box is 6' wide and 25' long or so. They have a header box with carpet and expended metal on top with a riffle every 3' to 4'. Nuggets have been found all the way at the bottom of the sluice..... so you know they lost many out the bottom. Loss rates are 40% to 50%, so looking to cut that drastically.
The majority of the gold is fine stuff. Unsure of just how fine right now.
Looking for any suggestions and inputs, especially on sluice design and matting.
I know that's not enough info and I asked a lot, but don't want to make too many mistakes getting started and don't know where else to turn.
Just my thoughts if you can send photo's to Doc and the GoldHOG team and let them evaluate and give you some suggestions because they are good at what they do. Sounds like there needs to be some much needed changes there. good luck and hope you get it figure out.
Yes, that's we having them do.
I picked up a garage sale sluice box that’s 6”w x 21”L with a 500gph battery operated pump. I plan on turning this into a packable self contained system to go anywhere high and low specifically in Southern AZ. I need to make a header box as well. Pitch is set permanently at 7* but of course easily adjusted in the field as necessary for proper flow. I will predominantly be running thru .5 - .25” classified granitic quartz material. Any recommendations for a layered mat selection to get me started will be greatly appreciated. I’m thinking of 2 sections of Scubber up top followed by 2 of Motherlode or the Bedrock 2.0 Thank you.
I don’t think you will have the water flow for the scrubber mat. Look at some of the low flow mats. Razorback or Downdraft paired with the mother lode mat could work well.
I agree with Dan...
8x21 is a tough box because it's so short, and only 500 gph limits water DEPTH and matting choices. MAYBE... downdraft all the way down and that's about it.
Thx amigos for the feedback I think ill get started using the downdraft mat and see how things workout. Pumps are cheap so ill upgrade that if necessary. Im also joining a local club in the area so that should up my learning curve. Thx again.
Can you suggest the best mat (s) to use in 8" × 24 " highbanker with 2000 gph bilige pump ?
Hello Del and welcome with such a short sluice makes it tough but I might go with a piece of talon at the top then go with lower flow mats like down draft ur maybe motherlode. If so check out Doc's videos a lot of good information there. Also gives you a good break down on each mat.
In your opinion, would it be better to stay with the set up the machine came with; ribbed mat , expanded metal , and Hungarian riffles than trying to change over to gold hog mats ? I'm trying to find a system that would be better in keeping fine gold in the sluice box . Thanks , Del
Well Az, I might have an answer that you COULD consider all or part of.
You have a narrow (6") but short set-up on this short (21") box . Now, since you plan to make a header box for it anyway - why not just convert this 6x21" box into the top of a longer sluice box by creating a bolt on box extension, designed to be just wide enough to insert the bottom of the upper box into the lower end and with the capability to crush/retain the lower mat)?
Even a simple 18 or 20" bolt on tail sluice wouldn't create much extra weight and it would give you, say, 36 or 40+" of total box to work with. With the extra length you could use a variety of Gold Hog mat styles to recover the larger specks as well as the really fine bits in the new lower end.
If you were able to use low turbulence mats in that lower end, provide a small and simple curtain/flap to smooth the water turbulence, and play with flattening off the pitch a little bit you would almost have a super lightweight Mini-Mini backpack highbanker. With Gold Hog mats in that box it would be The Cat's Meow and the envy of everyone who saw it.
About mats - a couple of thoughts:
You could create a Gold Hog mat configuration to have a bit more aggressive 'attitude' in the upper portion with the last portion of mat (a hair wider) more 'laid back'. Two or four lower box mounting holes in the rear of the upper box could be fixed, round and tight fitting while the lower "holes" could be vertical slots - allowing the inside box to drop and pinch / retain the leading edge of the lower mat between both boxes.
Water volumes would have to be tuned for the situation but after a short time that would be easy to get the feel for.
If you haven't studied this video before I would STRONGLY recommend watching it a few times (after the first time take notes).
Hey Doc - Whud Ja' Think 'Bout Dose Idees? 😜
Hi Del in my opinion I would still go with the gold hog matting for what ever u decide to do. I have been using the matting for several years and would not use anything else. It has no problem catching fine good I use in all my highbanker dredge combo's on Nome beach sands. Joe S Ak also has some good ideas to, hope this helps.
Yeah Dell, I used Az's handle instead of yours. OOPS. Both of you actually have about the same conditions in your sluices - so most of the suggestions still hold.
I also agree with Scrapper - stick with Gold Hog mats. Yes, they're confusing in the beginning since other equipment manufacturers usually just set up whatever system they like (regardless of what is best for you) and when you buy a previously owned item you just inherit whatever the former owner chose to use (scary at times!).
For now (it's winter or almost) start looking at ALL the possible carpets, moss, riffles and whatever else folks put in boxes to learn what's out there. When you do that pay particular attention to Gold Hog mats because many of us feel they are the best over a wide range of situations (allowing you to 'tune' the mats to YOUR needs). Watch the description videos on the various mats (some you can discount and others you should study and take notes on) and then talk with other miners. You'll come up with what you want to try based on everything you learned.
You might think about all this this way: You could start out driving a Mazaratti and get really good performance early on and have a superior driving experience from day one.
Another way to go is to find the oldest Chevy Nova that still runs and fight the old designs to try to get out of it just enough to get you by. After a lot of years frustration and endless effort you will still be just getting enough to get by --- until you see your first Mazaretti in action.
So, learn what you can, talk to folks, watch videos and come up with a replacement for that Hungarian riffle design (which is, of course, right from the Chevy Nova era).
Whatever you do I would recommend that you work from a position of knowledge.
