I was pretty happy here. My recovery barge for diamonds was complete and a good coat of paint, looked pretty good. We were getting the Generator wired into the Jig and water pump and getting ready to get it out into the water and dig for some Diamonds.
I am always on the lookout for new and interesting ideas, and out in a boneyard near Hydrabad, India was another amazing curiosity to me.
People in foreign countries are so resourceful. It may not seem like much but look how well some young fellow made this wire reel, almost completely out of wood. I just love stuff like this!!!!
This is our water system on our current gold mining project. I use the godwin pump whenever possible.
These are in my opinion the best pump on the market out there. Plug and play. The self priming feature is dependable and on my projects the last thing I want to do is fight a pumping system.
This is a screen system we use and it is very effective especially when you are recirculating your wash water. At the waterline you can see we made removable screens for fast cleaning when they start to plug up with grass, roots and other debris.
With three sides you never have to shut down. The pump intake is 4 ft under the waterline with a solid bottom insuring you get the cleanest water from the top of your settling pond. The catwalk and safety railing for sure is a good idea from a safety standpoint. Keep your pumping site clean and well maintained and this will help with keeping rock in the box and making gold!!!
This was for a little vibrating screen plant. This is a good example of a choke feed hopper with plenty of hopper water.
The deck below is a screen deck we also fabricated.
On the subject of hoppers, you can have vibrating variants that in some cases, can assist in the liquefaction of introduced pay gravel.
Depending on the type of gravel you have, a vibrating hopper is sometime a good addition to your washplant. Be aware more moving parts and maintenance, not to mention cost!!
Most placer gravels are free flowing and feed out to a screening system just fine with a choke feed system. Millions of yards have been successfully treated with this type of hopper.
A lot of placer mines have a high percentage of boulders in the pay streak .
One of the ways to manage these is to use them to your advantage. I like to stack them up on the side of the next cut. The reason for this is to essentially build a rock retaining wall for the purpose of clearly defining your next cut as you strip down to it.
This also helps keep dilution of the pay gravels from the overburden by using these boulders as a wall. Boulders are much easier to rake out and simply throw them back into your worked pit. I also like to use discarded stumps and trees along the edge if I have to. These can be a bit messy to work with, and the wood can come back to haunt you in your settling pond with the duff and tree bark plugging your intake screens if you are recirculating your water. This is something to keep in mind.
This is a set of hydraulic riffles I built a few years back. This was the underflow from a Pan American Jig.
We had a lot of blacksand and it contained significant amounts of gold. Regulating the water pressure to around 7 lbs on this particular job seemed to do the trick!
Really the biggest problem we had was handling the enormous amounts of black sand and being able to transport it upriver to a tabling concentrator. This was on a floating Diamond recovery barge I built.
