LIQUID GOLDFIELDS

The Rand may find anew competitor in Father Neptune if -success
attends the researches of Professor A,
Glazunov,;director of the mining college in Pribram, Czechoslovakia, who
has been exploring the possibilities of
extracting gold from sea water, says
the "Cape Times." ,


The professor, who recently visited
Paris attending the International Mining Congress, said that he and other
well-known Czech scientists have
been experimenting with sea .water off
theFrenchcoast, and at Madeira, and
have come to the conclusion that if
seawater contains six milligrams of
goldper ton, that is .000192 of an ounce
per ton, ;the production of gold from
the sea would be a commercial possibility.
Professor Glazunov. discovered' in
water near the coasts' of Europe a
gold content of only .000032 of an
ounce per ton, but he quotes scientists
who in the past have found. a
higher content elsewhere. He refers
to Liversidge, who claimed in 1895 to
discover .0016 oz off the Australian
coastr-which professor Glazunov doubts and Don,  who' found .00032 near California. 

The professor himself thinks that the
Pacific coast of America would be a
good place to "prospect" for liquid
goldflelds. '..''".;■""'.■■ : "■""- : \

He considers that the; gold content
in the sea.water..dependsfirstly: on the"
volume of micro-organisms in "the"
water; secondly on the" presence of
pyrites and quartzes;. and thirdly, the
chlorine content of.the water. ,■

The cost of prospecting is small—
almost limited to the salary of 'the
chemists—but the cost of the installation of plant for the production of 650z
of gold per annum he estimates at
about £2,000,000. " ■

He 'would propose filtering the sea
water through pyrites which would
absorb the precious metal.
As mechanical power would be too
costly, Professor Glazunov thinks the
power of the tides could be utilised.
A bay in the selected district would
have to be closed with a special
double-walled dam; and special' baskets of pyrites placed between the
two'walls. Sulphuric ore would' retain daily a certain amount of gold.
The production of 650z-of gold would
require about 10,000tons of pyrites,'
and quantities of sulphuric acid would
be produced as a by-product when the
pyrites were burned to extract the
gold. .'...-.-"■:

Professor Glazunov said that two
financial
groups, one in Zurichand the
other in America, were interested in
his researches.
