From blasting to crushing to separation – more than 85% of the iron
mined in China is mined to make our nation’s steel.
Taconite Processing Plant - Blasting
Taconite is a very hard rock. Using explosives, the taconite is
blasted into small pieces.
Taconite Processing Plant - Transportation
The taconite pieces are scooped up by electric shovels. Each shovel
can hold up to 85 tons of rock. The shovels place the taconite into
giant dump trucks. These trucks are as big as a house and hold up
to 240 tons of taconite. The trucks take the taconite directly to
the processing plant, or the taconite is transported if further
away.
Taconite Processing Plant - Crushing
At the processing plant, the taconite is crushed into very small
pieces by rock crushing machines. The crushers keep crushing the
rock until it is the size of a marble. The rock is mixed with water
and ground in rotating mills until it is as fine as powder. Jaw
Crusher, impact crusher, roller crusher, cone crusher, ball mill,
etc, are all suitable for plant.
Taconite Processing Plant - Separation
The iron ore is separated from the taconite using magnetism. The
remaining rock is waste material and is dumped into tailings
basins. The taconite powder with the iron in it is called
concentrate. Magnetic machine, flotation cells, etc, are much
better for the processing.
Taconite Processing Plant - Pellets
The concentrate (the wet taconite powder) is rolled with clay
inside large rotating cylinders. The cylinders cause the powder to
roll into marble-sized balls. (This is like rolling wet, sticky
snow into balls to make a snowman). The balls are then dried and
heated until they are white hot. The balls become hard as they
cool. The finished product is taconite pellets.
Taconite Processing Plant - Steel
The taconite pellets are loaded into ore ships, trains, or trucks
for delivery directly to steel industry. Contact with me
