Historical and Present day uses For Potassium
There are few uses for Potassium as a pure
element. Most of the time it is combined with
something else, and there are many things that we
need that have Potassium in them. The most
important reason why we need this element, is
because it makes up most of fertilizer, and we
could not have plants without fertilizer. It is
also used as a heat exchange medium, and is
essential to plant and animal life. It helps the
human body by controlling the proper balance of
fluids in cells and other body fluids and also
assists in the digestion of food and proper
function of the eyes.

Where found on Earth
Potassium is found in numerous places throughout
the Earth. Most of the time it is combined with
another element, and there are few uses for
potassium as a pure element. The most important
source of potassium is from a mine near Carlsbad,
New Mexico. Potassium is found in many foods as
well. We know it best, to be found in bananas,
which contain large amounts of it.

How its Collected
Potassium is collected by running water into, and
through the mines. The water returns to the
surface and is allowed to evaporate. The PT
compounds in the mine remain behind when all
water has passed through, allowing us to collect
them.
