recirculating sluice box

[tweeta_bear]

here is the supply tube i made... im wondering if the holes are to small.

Hook it up to the supply and run it. If the water is spraying out the holes, you need to open them up a bit.

 

[tweeta_bear]

i will... i have run into a snag, the 1" tubing is $5.59 a foot so i am going to hard pipe it.

 

[tweeta_bear]

how many gallon tub should use for sluice box? does this look big enuf?

I hate say this again but "it depends". It depends on the the amount and type of material you are going to run. If the black tub is the gravel catch, it's probably going to fill up fast. If you don't catch it before it overflows, you are going to be sucking sand into your pump. If you run material with clay in it you are going to have gumbo before long.

My initial feeling is "no" it's not enough. I'm thinking a couple of surplus 30 gallon barrels with a PVC pipe connecting them. Bilge pump goes in the furthest barrel.

i will be classifying my material down to 1/4' and the material will be from gravel bars, behind boulder in the steam i live in colorado and most of what i will be getting will be from clear creek colorado down stream from central city and black hawk, down stream from the famous glory hole in central city colorado. not much dirt mostly pee gravel and black sand.

 

[tweeta_bear]

my whole plan is to run up the hill (its only about 23 miles) classify a few 5gallon buckets from the stream an bring home.

 

[tweeta_bear]

now i just have to figure out how to get it to drain from one to the other without leaking all over the place.

here is my classified material.

PVC pipe and silicone.

i was thinking a bathtub replacement drain i just dont know if thats big enuf. i got a 2200 gph pump, should i make it a 3 or 4"?

 

[tweeta_bear]

i know they dont make a 3 or 4" bathtub drain, that is in reference siliconing in a pvc pipe.

 

[tweeta_bear]

is this going to be low enuf or do i need to raise it?

 

[Jason in Enid]

Well, for starters those don't look close to 30 gallon barrels, but use whatever you want. As for the drain pipe, yeah it needs to be higher. The purpose of the multiple barrels is to act as settling tanks to let the majority of suspended particles drop out before reaching the pump.

 

[tweeta_bear]

what should i use for the water catch basin? this is what i had and didnt have to pay anything besides i wasnt using them for anything. i still plan on putting a 5 gallon bucket inside the top bucket to catch the tailings. it will really act as a 3 stage drop. into the black bucket into the second bucket and the drain to the third bucket.

 

[tweeta_bear]

oh and they are 20 gallon tubs.

 

[tweeta_bear]

ok here is another question. im going to cut and glue this together then silicone around the inside and out. should i put the 90 down into the third bucket or down into the second bucket.

 

[tweeta_bear]

well it was obvious once i got the hole cut out the 90 has to go outside of the bucket.

 

[KevinInColorado]

Yup. Looks like you are on the right track!

 

[tweeta_bear]

PVC pipe and silicone.
