- Manganese is a
chemical element, designated by the symbol Mn.
- It has the atomic
number 25. It is found as a free element in nature and in many
minerals.
- Manganese is a
gray-white metal, resembling iron.
- It is a hard metal
and is very brittle, fusible with difficulty, but easily oxidized.
- Manganese metal and
its common ions are paramagnetic.
- Manganese is a metal
with important industrial metal alloy uses. Manganese ions are variously
colored, and are used industrially as pigments and as oxidation
chemicals.
- Manganese metal is
ferromagnetic only after special treatment. The pure metal exists in
four allotropic forms. The alpha form is stable at ordinary temperature;
gamma manganese, which changes to alpha at ordinary temperatures, is
said to be flexible, soft, easily cut, and capable of being bent.
- Manganese has played
a key role in the development of various steelmaking processes and its
continuing importance is indicated by the fact
that about 90% of all
manganese consumed annually goes into steel as an alloying element.
- Manganese is a key
component of low-cost stainless steel formulations and certain widely
used alumimum alloys.
- Manganese dioxide is
also used as a catalyst.
- Manganese is used to
decolorize glass and make violet coloured glass. Potassium permanganate
is a potent oxidizer and used as a disinfectant.
- Other compound that
find application are Manganese oxide (MnO) and manganese carbonate
(MnCO3): the first goes into fertilizers and ceramics, the second is the
starting material for making other manganese compounds.
- Manganese is found
widely in nature, but occurs only in trace amounts in human
tissues.
- In the human body,
manganese functions as an enzyme activator and as a component of
metalloenzymes.
- Manganese activates
the enzymes responsible for the utilization of several key nutrients
including biotin, thiamin, ascorbic acid, and choline.
- The human body
contains a total of 15-20 milligrams of manganese, most of which is
located in the bones, with the remainder found in the kidneys, liver,
pancreas, pituitary glands, and adrenal glands.
- Total world
production of manganese alloys reached 11.8 million metric
tons.
- Out of a manganese
ore production of over 34 million tons per year, 13 million tons come
onto the international market. A few producing
countries, Australia,
Brazil, Gabon and South Africa, account for over 85% of the world’s
supply.
- Today, most of the
manganese requirements of industrialized countries are supplied in the
form of alloys. As a result, the UK and Germany have has almost
completely abandoned local production of manganese alloys and the USA is
now only a minor producer. In Europe, countries such as France, Norway
and Spain have continued to be large exporters of these
ferro-alloys.
- World demand
for manganese depends directly on the needs of the steel industry.
- There are
numerous grades of steel and each requires a different amount of
manganese.
- Unit
consumption is determined by calculating the average requirement of
manganese per ton of steel.
- Some
manganese which is to be converted into steel is present in the iron
(hot metal) coming either from the iron ore charge or from the addition
of manganese ore to the blast furnace.
- The production
capacity of electrolytic Manganese matalsin exceeded 300,000t. The
number of electrolytic manganese matal plants is around 60. The annual
capacity of the largest one is 200,000t.
