G'day Homesouth,

This will be an interesting auction to follow! The gold picture does looks familiar ... I think I might even have seen it previously on the web ;D.

With this auction, the "ones that get off on pepper gold" will again be lining up to offer their theories on the recovery of fine gold. Expect to read and be bored by even more loopy thesis on how to make a fortune from fine gold. Coming up with theory's on fine gold recovery is becoming an industry in itself ... but, of all the theories I've seen written up on the Internet I'm yet to see anything new that has progressed from a theory to being successfully used by real-world miners. It has often seemed to me that the theoretical miners live in another world where real and demonstratable results don't seem to matter and the fun is solely in theorizing (but its all harmless enough, I guess).

G'day Homesouth,

It only took a quick web search to find the gold photo

Hi Rob
We need some of the boys in the back room to come up with a way of getting rid of the blacksand on beaches and central otago. Been thinking of all sorts. The best I saw on fine gold was a guy using polar fleece , think I had a pic up on the last forum. Pretty sure it was from NZ. But working fine gold I can see why there were so many pubs on the coast in the rush days It would drive a fella to drink. Reminds me of a saying about avoiding strong drink, it makes you shoot at tax collectors (fill in person of your choice) and miss. Cheers

G'day Homesouth,

In my opinion the key to solving the black sand problem is simply to use Hydraulic riffles. And as we all know, just about all of the South Island trommel plants use hydraulic riffles, so its an already well proven method of fine gold recovery (in effect industry best practice).

Where the innovation comes in with hydraulic riffles that is of interest to us, would be their use on Production (eductor) dredges. The accumulation of the heavy black sands (which are more abundant in the South Island gold fields than in any other gold field anywhere in the world) in sluice box's is what makes fine gold recovery the major problem it is in New Zealand. And hydraulic riffles are particularly effective in ensuring the fine gold is trapped in a sluice box and do not run over the top of hard packed black sand to go out the end of the sluice box ... but hydraulic riffles do need to be used in conjunction with processes for treating the sluice box concentrates such as removing the magnetic black sand
(such as with one of these

before running the concentrates through something like a Gemini table

G'day Homesouth.

Here is a plant that is presently in operation that is mining fine gold from near a beach ... anyway close enough to be called a beach deposit

Hey

Think the guy may be stretching the conditions a little on his mining permit which states " Small Motorised Equipment"

Not to sure if a 20 Tonne Digger falls under that class..

Cheers

These things are pretty small, and good for gold to 0.002mm:

Just got to figure how to float the rest of the kit on a tube.
