Hello Jose and List,

I found the possibility of recovering manganese nodule
from depths of only "50m" to be very intriguing, so I
searched a little more deeper on the Internet. But I
failed to find that claim to be supported anywhere in
the literature. Even 500m is much too shallow of a
depth for manganese nodule formation. I found several
references which reported these nodules having been
found at depths of 5000 feet.

Would it be possible to find that newspaper article
that you made reference to? Because if it were truly
possible to recover those nodules from that shallow of
a depth, it would make the "mining" of that form of
ore much more economically possible.

What I did find were more reports which confirmed that
these nodule are very POROUS, which convinces me that
the item up for auction is NOT a ferromanganese
nodule, regardless of questions about depth of
formation. The density of this item is more
suggestive of something much more commonly found on
eBay: "sulfide slag" !!

What I hope results from all this OT discussion, is
that the "winning" bidder for this item gets it
properly identified and the results are finally
published here on the List.

Hi Bob Verish and List,

The reference made to "rare manganese nodule samples
from 3000 meters deep
on the Pacific Ocean floor", reminds me of when I used
to live in South Africa, I recall having read in a
local Durban newspaper, about this south african group
of sea-divers who, - some 2 years before South West
Africa (which at the time, was a South African
Protectorate), became an independent country in 1990,
as Namibia, - they were given a licence to explore a
portion of the sea-floor along the Skeleton Coast, and
they used ships with powerfull pumps and pipes to
vacuum the sea bed, near the coast, for lots of
manganese nodules, most in 50 meter deep water - if my
memory serves me correct.

The link above shows a manganese nodule, which is more
like I remember how they look. The light-colored
shiny interior of the specimen in the eBay auction
looks every bit like the kind of meteorwrongs that I
have been seeing a lot of lately, and which we have
given the collective name:
"sulfide slag"
as described on Ken Newton's web page:
