While not a part of the Algoma Eastern physical plant of the
1930s, the Iron Ore Pellet Loader deserves a place on this
tour, if for no other reasons than it was both a major
consignee of CP Little Current Sub traffic in the 1970s and
80s and a significant and familiar part of the Turner docks
for many years.
The early 1950s brought changes in the refining methods
of Inco's ores. The Sudbury basin nickel ores contain
significant percentages of other metals,

including iron ore. After
the second World War, Inco began investigating the possibilities of extracting the
iron from the ore, thus providing another revenue stream from the Company's
Copper Cliff operations. The results of these
experiments lead to the commissioning of Inco's Iron Ore Recovery Plant in Copper
Cliff in 1956.
Although the product of this plant is called iron ore, it
is not the same as iron ore which is dug out of the
ground. The process produced a small round pellet of
enriched iron ore, about a quarter to a half inch in
diameter. These pellets were somewhat heavier than raw
iron ore, but the increased iron content made them far more
economical to ship than raw ore.
Sometime during the sixties, Inco constructed the Pellet
Loader on the dock at Turner. It soon became a major
transhipment facility for the output of the Iron Ore
Recovery Plant.
The ore was moved from Copper Cliff to Little Current in
hopper cars via the CPRs Webbwood Subdivision to McKerrow
and thence south on the Little Current Sub to Turner.

Full cars were shoved up an elevated unloading siding
located about 200 feet behind the Pellet Loader between the
dock and the yard. At the top of this siding, almost
directly across from the Turner engine house was an open
deck plate girder bridge through which the hopper cars were
unloaded onto the ground below. The unloaded pellets
were moved by rubber tired loader from the unloading area to
one of a number of storage piles of pellets located on
either side of the unloading siding both east and west of
the Pellet Loader. Just in front of the unloading
bridge, between it and the Pellet Loader was a single story
concrete structure with two sloped grizzlies on either side
of it. This structure
contained a hopper, into which the rubber tired loaders
dropped the pellets to be loaded into waiting lake
freighters. The bottom of this hopper emptied out onto
a covered conveyor belt which transported the pellets up
into the loader.
The Loader consisted of a tall corrugated metal enclosed
tower that looked very much like a typical Sudbury mining
headframe. The loading portion of the structure

consisted of a long metal truss loading arm which could be
swung out from its resting place parallel to the dock on the
east side of the tower to its loading position at right
angles to the dock. When a freighter to be loaded had
finished docking, the loading arm was swung into position
and loading commenced. The pellets which had been
carried via conveyor up into the tower were dumped onto
another closed conveyor which ran from the base of the
loading arm out to about half its length. Slung
underneath the loading arm was a moveable conveyor belt,
again about half the length of the loading arm which could
be run in and out so as to reach all parts of the hold being
loaded. The pellets dropped onto this moveable
conveyor from the fixed conveyor and were carried out over
the open holds. The pellets then dropped off the
moveable conveyor, through a metal funnel and into the hold
of the ship. The operators cabin was up on top of the
loading arm where he could see what was going on and adjust
the arm and the movable conveyor to suit. The loading
arm could also be moved vertically to bring it closer to the
ship.
When not in use the moveable conveyor was run down to the
inner end of the arm, which was swung over so the outer end

This facility continued in use until 1991 when the Iron Ore recovery Plant
was shut down. The pellet loader was removed in 1998.
