resource industries are all dependent,
in some way, on the mining industry. The mining industry will continue to
be an important support to the economy.

Mining is taking full advantage of the quick expansion of computers and
microelectronics. These technologies are found in nearly every aspect of
mineral development activity - from exploration methods, through production,
mineral processing and even marketing. Computers and related equipment now
have a lot of different applications in geophysical logging, geochemistry,
geological mapping and surface contouring5. At the mine planning stage,
the job of designing a mine is now greatly simplified by automation.
Through the use of advanced software, geological models can be produced
from drill hole data. Computers are also being used to develop plans for
mine expansion, develop mining schedules for yearly, quarterly and in some
cases, weekly operations. At the operating stage, this new technology is
everywhere6. Both in ...

may be complicated or relatively simple,
depending on the mineral content of the ore. Milling processes are

treats the metal-bearing concentrate further, up-grading it to purer form
called "matte". Basically: The ore concentrates are mixed with other
materials and treated at high temperatures to change the material to other
chemical forms. The metal in the matte can be separated further. Further
treatment is applied to the final purification of the metal and ...
