1.Description
Manganese compounds have been used by man for thousands of years. The ancient Egyptians and Romans used manganese compounds
for dyeing in glass manufacture. In 1774 Johann Gottlieb Gahn succeeded in extracting pure manganese from brownstone. In the structure
of the earth's crust manganese is the second most common heavy metal after iron.
Important manganese ore deposits are to be found in South Africa, Australia, India, China, Mexico, Ukraine and Russia amongst others.
"Manganese nodules" can also be found in the deep sea.
