Zinc Mining
80% of zinc mines are located underground, 8% are of the open pit
type, with the remainder a combination of both. In terms of
production volume, underground mines account for as much as 64% of
overall zinc production, combined underground/open pit mines
provide 21%, and the remaining 15% is sourced from open pit mines.
History of Zinc
Centuries before zinc was discovered in the metallic form, its ores
were used for making brass and zinc compounds for medicinal
purposes. Zinc compounds were in the ores smelted certainly as
early as 200 B.C. to obtain copper and which gave alloys of copper
and zinc – the brass family. The Romans certainly were major users
of brass. The Greeks also appeared to know zinc, even if not by
name.
An ancient idol, containing 87.5% zinc, found in prehistoric ruins
in Transylvania in Eastern Europe is the oldest known zinc object.
Zinc filled silver bracelets dating back to 500 B.C. have been
found on the island of Rhodes, and the Romans used a zinc alloy to
fabricate coins.
Some credit India with developing the first knowledge of true zinc
smelting while others attribute its discovery to the Chinese. The
production of metallic zinc occurred much later than other common
metals. Copper was smelted from its ores around 5000 B.C., lead
about 4000 B.C. and iron about 2000 B.C., while zinc appears to
have become available on a commercial scale in the 14th century
A.D.
In Europe, zinc probably became first known through its import from
India and China. Zinc was recognized in Europe as a separate metal
in the 16th century when Agricola (1490 – 1555) and Paracelsus
(1493 – 1541) wrote of a metal called “zincum.”
