sluice (6)

10" x 8' drop riffle design.

Wa. rules dictate 3' sqft. of riffled area outside the work windows and 10' sqft. within the work window (work window = Dredging allowed)

I have settled on this basic design drop riffle design with 2.5sqft of 1/2" riffles area  below a 4' of slick plate.

While building this template negative I decided to make it into 2 pieces for easy transport. Simple as adding a flange to the riffle side to connect the 2 halves.

I am going to add a screen (12" x 10") and upper deck over the riffle area using more fiberglass 42" x 10". The screen is going to be a 1/8-1/4" wire freezer rack /1/2" to 3/4" spacing. A wire screen. 

The spacing between the riffle deck and discard plate above it is not set yet. Mainly because I'm not sure how far it should be apart.  An ideas here would be nice.

I'm in the tedious process of applying wax as the release agent for the fiberglass. Since this will be my first attempt at a mold like this I will be doing a test run to make sure it releases correctly. 

Once this section is completed I plan to add more riffles to the slick plate and make one long riffle area for in season work windows. All in due time, I'm slow and completing project with life moving around me.

Pans!

I don't know how many times people have come up to me and said, "All you really need is a pan to find gold." Technically that's true. All you really need to find gold is a pan. At some time, even with machinery, you will probably pick up a gold pan. Maybe not at the start, but more than likely at the end.

However, gold is a numbers game. The more dirt you process, the more gold you will find. Unless you hit the Mother lode, and are digging nuggets of gold. You are dealing with something much smaller. From flour to flakes to pickers. (Sounds like a double play team in baseball. “5-4-3 Double play!” I can almost hear the PA announcer.)

That’s where machinery comes into play. However, this isn’t about machinery, it’s about pans. Probably since the dawn of time, or at least when man first discovered gold, there have been gold pans. Sluices made of gold, were discovered in King Tut’s tomb. I would imagine there were gold pans made of real gold as well. But even before that, most likely pans were made out of slices of a tree trunk dished out. Wood has one problem, it swells, shrinks and cracks. So maybe the first real gold pans, as we know them, were made during the Bronze age.

However, where you find relics from gold rush times, you will find wooden pans. They could be turned out on machinery run from water wheels driven by long belts. Someone had a bright idea to go to the maker of a Knights armor and turn out gold pans. These would have been made of iron, as a Knights armor were iron plate. Eventually steel came into play, and I’m sure steel gold pans followed.

A mixture of steel and wood pans have been found from California to Australia. The Chinese prospectors are credited with introducing the riffle to the Gold pan. And you can still see a form of it today in modern steel pans. Prospectors really like steel gold pans because it served two purposes. First, of course, it was a gold pan. Second, it was their dinner plate. The pan could withstand heat, they ate off of it, cleaned it up and go back to prospecting. Maybe old time prospectors were the original , “Multi-taskers”?

Back in the mid-70’s, 1970’s that is, I’m not THAT old! I started with pie pans, which I liberated from my Mom’s cupboards. (Liberated sounds so much better than just helped myself, without ask asking. IE: Stole!) I had already been bitten by the Gold bug at age 10. However, I had no clue on how to actually find gold. (My first discovery was Pyrite, that I thought was gold.) I met a couple of guys prospecting the Whitewater River in Southern Indiana. They both had steel pans with grooves formed in the sides. They had found these in the back of “Popular Mechanics” magazine. (Might have been “Popular Science.” It’s been a long time for my memory.)

They are the ones that told me to,, “go get your Mother’s pie pans.” They had a wooden homemade rocker box lined with Shag carpeting! (This was the 70’s.) Back then, I didn’t know anything about flour gold. I thought all gold were nuggets, or at least pickers. So, I’d sift through sand from the river looking for gold I could see. I pretty much never did.

Fast forward to today. Today we have gold pans, still in steel. However, now there’s copper and the most one used are plastic. Plastic has opened up a world of new shapes, sizes and colors. (Again, another Triple Play team?) Today’s modern plastic pans come in round, square, rectangle, triangle, hexagon, U-shaped, to name the popular ones. And just about every color. Blue, green, red, black, purple, maroon, white and pink! Blue and green are the most popular, followed by black. Green and blue will make your gold stand out as well as your black sands. Black pans will make your gold “pop” out, but will hide fine black sands making final clean up difficult. The other colors, have their fans. I like blue, maroon and red for final clean ups.

Green is the most popular, but if you suffer from color blindness, then you want to stick with blue. Blue pretty much is still blue, throughout most color blindness. However, green can show up as various colors, including shades of yellow. They also come with various sizes of riffles. From no riffles to quite large riffles.

Sizes. Plastic pans range from 10” to 16”. Again, typically, bigger pans are used to work off the dirt and gravel and smaller pans are used for final clean ups. 16” pans can be a hand full, especially loaded with dirt and gravel. 14” can be as well, but is still easier to work off. 10” pans you can use one hand, but you’re limited to the amount of over burden you can work off at one time.

So, there you have it. Most small scale prospectors have many pans in there inventory. Lately there seems to be 1 - 2 new pans coming out every year. They always seem to have their supporters and their opposition. Like I always say, it’s what works best for you. I always seem to end up buying the new ones and trying them at least a few times.

Until next time, this is the old prospector.

Good Hunting!

Perhaps you would like to improve your outdated gold sluice box also called a crash box sluice. Your gold sluice box on the dredge is unquestionably a crucial part in the building, I have done up a different web page about it so that you could see all of the setup and just how I actually made my very own.

Old Dredge Gold Sluice Box

I’ve got a Four inch gold dredge which has been useful for several years on a variety of destinations while in the California mother lode gold rush region. Not too long ago I replaced the older dredge water pump designed for one having increased volume – the master plan was to obtain better suction power. This worked well, however i recognized a substantial decrease at my fine gold retrieval. I understand the fact that older crash box design and style gold dredge sluices are terrible in retrieving fine gold, but if you up the waters velocity an excessive amount, well, it truly can make issues a whole lot worse. I actually recognized I had created an issue, nonetheless when gold dredging throughout 2009, I observed a little gold nugget had worked the way all the way down the gold sluice box towards the Sixth riffle – it absolutely was heading it’s way out of the end of the sluice box. I later on weighed the gold nugget and this entered in at Eight grains, therefore i thought if perhaps gold this size could possibly work their way through, the fines or flake retrieval really was terrible so i was required to do some thing. I simply couldn’t procrastinate any further, so i started to take into consideration my possibilities. Primarily due to the price, I made the decision in making my very own homemade gold sluice box. I was without any kind of layout plans or even particular instructions, however I’m a mining industrial engineer through qualifications, and also I own as well as have the needed steel manufacturing tools, therefore, the job didn’t seem to be past my reach. Furthermore, the actual 49ers fashioned and created their own personal gold sluice boxes, so just why wouldn’t I produce my very own? Also i calculated I would reduce my cost in doing the work [...] Reed More

Sluice Box Set-Up & Useing Of Sluice Box

. Too much water, going too fast will probably hold gold higher within the suspension. This scientific disciplines could be tough to go into detail, however fundamentally the top level water will not be impacted by your riffles just as much as the bottom level. As the lower level will be running behind a riffle, the top will be sweeping right above the eddy, even though the actual eddy by itself may slow the top part alittle, it is not as helpful by the actual riffle on its own.
