brigade As near as science has made
things possible the plant works auto
matically, from the receiving of tho
ores at the tramway to the converter,
ladle and molds.
The tramway from the Utah Console
dated mine over the mountain In Bing-
ham to the plant Is now WORKING
smoothly although Il has not entirely
worn of the edges. During the week
the tram made a record of putting $50
tons OF ore In the smelter bins in eight
hours and II minutes. 1t is making
an average OF 100 tons an hour and
there is no doubt but what with three
shifts 1000 tons every "a hours could
be handled
The brick men completed their work
at the smelter Thursday and the steel
men have gone. only few details
are being cleaned up and the debris
left in the building is being carried
away. The place will soon be as clean
as a park.
MATERIAL REQUIRED
The building OF the plant required
$500 tons of steel. 3 900 tons OF which
came from the old Highland Boy
plant steam shovels and teams ex-
cavated 100000 yards Of dirt for the
buildings, 1,75O,O0O brick were used
In the stack alone. which is $50 feet
high. and $4,000 yards OF plain and
reinforced concrete were used in put
ting In the magnificent power house
and other buildings and foundations.
unlike many plants the entire Pine
canyon smelter is under cover The
terminal OF the tramway is covered
From receiving bin the ore drops
down into an electric car carrying 80
tons. After being weighed on scales
that punch automatically the weight
or the car on a card, the ore then
moves on 10 the receiving bins These
bins hold close to 10000 tons of ore
and are also under cover At present
the bins are nearly full
The sampling and crushing is done in
2 20 by 2o-foot steel building. which Is
hve stories high. The work here IS
done automatically. In samplins the
ore Is fed through a 2ixi2-inch Blake
erusher, the crushed ore then being
elevated and first cut Of one-ffth.
Is taken as sample. Another cut e
taken after running the ore through
a 20NlO-inch Blake crusher This sam

4sxl2 rolls and last cut made from
2sxl5 rolls.
