Schulein and his co-workers in

per cent, Schulein said.
The metallic chromium is melt
ed down with pure iron to pro
duce ferro-chromium, which has
a wide variety of uses because of
its hardness.
Schulein said his product is
without carbon, an additional ad
vantage over the furnace product.
“1 estimate that I can produce
pure chromium from low-grade
domestic ore at the cost of the
lowest grade ferro-chrome,’’ said
Schulein. “The United States im
ports about one-half its chromium.
With perfection of this new pro
cess, the Pacific northwest could
supply the entire domestic demand
of this country.
The American market demand
for chromium is about 300 tons a
year, Schulein said.
The electro-chemical process
requires about 40 killowat-hours
of energy to produce a pound of
chromium, Schulein said.
Low-
cost power from Bonneville will
be an important factor in develop
ing such an industry, he indicated.
Schulein has set up the process
es of his experiment on a labora
tory basis for demonstration at
the state college.
Plans are being made for a re
duction plant in Portland, he said.
