RIO MARINA – the
land of iron
Of the many
sightseeing areas on the island, you cannot
miss the “iron” itinerary. The
island’s mining area covers 1,948 hectares
and includes the Rio, Rio Albano, Calamita,
Ginevro, Sassineri and Terranera mines. These
areas provide an excellent example of the relationship
of important geo-mineralogical phenomena with
mining activity that has developed over three
thousand years. In short, natural processes
set in a picturesque landscape.

The Etruscans began to exploit
the mines as early as the eighth century BC.
Iron mining went hand in hand with an intense
iron working activity, to which the remains of
numerous furnaces bear witness. With the innovations
brought by the industrial revolution, mining
continued up to the early ‘eighties, when
it was brought to a halt. The island’s
mines are not depleted and in fact it is estimated
that they still hold over 16 million tons of
iron.
In
the Rio Marina mining district, during the summer
months, it is possible to visit the Bacino site,
an authentic iron mine where the Elban miners
toiled for over a hundred years.
Here, industrial processing took the form of
opencast mining, for which the wide shallow step
technique was used over a heavily fractured area
where oxide and hydroxide masses combine with
layers of quartzose conglomerates and the underlying
metamorphic schistose rocks.
Haematite
is the main mineral and is considered amongst
the finest in Europe; the Elban version of
this iron oxide is known as oligist.Other minerals
on the island include pyrite and quartz crystals,
either white or reddish with haematite, while
widespread incrustations of copiapite can be
seen in the spring.
You are surrounded by a natural museum. With
just a little patience you will come across iron
minerals there, in the very place where nature
put them, and be able to see and touch them as
they rise above ground.
To satisfy
the growing number of requests from the many
people interested in mineralogy and geology,
the Bacino site is now open to the public.
Today visitors can get a taste of what will
soon be one of the biggest mineral parks, and
benefit from a life-size model of all that
the abstract treatment of specialised text-books
fails to illustrate clearly; in short, one
of the greatest exhibitions in Italy.
