Shaker Table - Page 2

Since I have a lot of this saved up, and returns seem to be about 0.6-0.7gms per Lb.
I have a good amount of Gold there.... Ounce plus... :-)

And since I have about 200kg of plastic coated Copper wire, selling or burning is my only option, till the shaker table and a homebuilt chopper would give me the chance to get #2 price with a clean process and over 99% recovery of Copper.
My yard only pays the lowest return % for plastic coated wire.
And 50kg of my wire is the 4 x2 strand telephone wire with no outer cover = 85% return...

My quick question is, are the riffles tapered in height towards the end?
I am thinking that 'baby corrugated iron' could be used as the riffle board if its not nessesary to taper them.
Everything else seems pretty easy, I have lots of time to build one, its a investment in that time too.

A couple of days ago my neighbours son popped over to ask me about 'making a home built casting furnace' for melting Ali.
He had a mid 70's book with some rough details in it.
I pointed out some stuff for him, like we cannot get the cement here, crucibles are far too expensive here and his size ideas a bit too small.
And it will not melt Cast Iron..
But, I dragged out a diesel furnace burner/blower I have, showed him some gas bottles for casting in, mentioned using kittylitter & sand & cement, along with some refractory insulation as cement and recycling cast Ali as Ali for casting.

So I think we could make one between us. And I can use it to incinerate silicon chips....
He can do the actual physical work and I supply parts and ideas, nice deal.

I gotta say alloy2, without the shaker table idea, it'd be a used gas bottle as curcible on gas hob and Gold pan the wires out....by hand.

Using a shaker table would be perfect for Gold mining in our areas too, there's no 'claims' for hobby panning/mining here, just free areas to do it in and a 'environmental' guide to follow.

Hobby mining is about a Ounce a week and less...per person. NZ$1300 a Oz?

If I were only running copper chops or coarse gold over the table would use none tapered riffles then for fine gold tapered.

I would avoid using iron crucibles, molten aluminum becomes a solvent when molten and will pick up impurity’s from the iron creating an unknown alloy which may make any castings you make brittle.

Cool picture of some local quartz, wet with water gives it an electrifying ghosting effect.

This is not a nugget, just some gold from inside a fissure.

Specimens such as this arsenopyrite have been known to contain some serious amounts of gold. The problem is that the gold is locked up in arsenic and that the ore must first be crushed then roasted to recover the gold.

The specimen below weighs over 5 lbs.

All I wanted was a 2kg bar of gold to call my own instead gawd with his sense of hunoir gives me a mountain of platinum.

This is a continuation of my past summer project at the waah plant. I have isolated the source of the platinum to two different sources.

That black sand at the wash plant contains a cosiderable amount of platinum but the mother load is in the rock of the out crop located at the pit.

The rock samples taken from the outcrop initially look black but after pulverising are really green in color.

The pulverised rock has visible inclusions of platinum along with some sort of sulphide mineral insoluble in both HCL and AR none magnetic to boot.

New learning curve coming up on sulphide minerals.

But the constant use of grey matter keeps it interesting.

Use of smartphone makes it difficult to post pictures. If you look at some of my back posts there are pictures of the wash plant and out crop.

The outcrop is the source of the platinum found at the wash pit.

We do not have a core drill but have the equipment nessesary to drill blast holes. So were going to blast some rock to get at some fresh un weathered rock.
