Our Beautiful World
During the Stone Age rock were important resources for the Stone Age People.
But are yuo aware that rocks still are among the most important resources
in the modern society?
Well, read on....
Quartz (SiO²) is the raw material of a lot of important products.
The photo shows what quartz look like in raw form.
It comes from the quartzine mine at Austertana in Finnmark,
and is produced by Elkem Tana A/S.
They are one of the largest employers in the municipality (which however doesn't mean so much in such
a small municipality), but they run one of the largest quartzite mines in the World.
Have you looked into your computer to see if there are any traces of Quartzite?
Then, don't do it again.

Not only is Elkem Tana A/S it the largest quartzite quarry in the world,
but I've also heard that the rock they are drilling in up there
is almost as hard as diamonds.
Several hard working drillers are working around the clock
at the stone and gravel quarry in 17 shifts per week.
These guys manage to pump out 1.2 million tons of rock
while drilling about 40,000 drillmeters each year at the quarry.
What makes their work so special is the nature of the rock,
which is approximately 99 percent quartzite.
With rock this hard, virtually all normal drill bits, in the words of the drillers,
just quickly "turn to butter."
how hard is it? Well, the locals say that on a scale of 1 to 10,
Copco Secoroc has created a specially designed 76 mm drill bit to
meet the challenge.
the rock isn't the only challenge up here.
