Chrome Brings
A LARGER sum
THANEXPECTED
Letters Received Tell of Profits
and Give Many Details on
Dioxide Factory

Two letters were received TINS
morning relative TO Mineral Products,
one touching on the chrome shipments
which have netted more than was
expected. from r. j. Pratt. and one
relative TO the manganese dioxide fac
tory from General Manager II. G. Gin
AGA. which is considered the best ana
most comprehensive letter on this
subject yet received.
Assistant Manager Pratt says. IN
der date of October "a:
I'VE beg to advise you that we re-
ceiYed this morning check from the
Carnegie Steel Company for S26l6.l9
in settlement for the first three cars
OF chrome Gre which we shipped them
last month. The analysis given by
them ran 45.53 per cent. 44.54 per
cent and 1901 per cent chromium OK
ide. average of each of these cars.
This ore therefore Melted us S20.69
per ton, which we think is a satisfac-.
tory price.
Yours Yery truly.
MINERAL PRODUCTS CO.,
"ROBT. J. PRATT,
Assistant General Manager.
Manager Ginaca says in part under
date of October %:
THE alterations to the digesters,
mentioned in our No. 1876 as being
made, were completed last week, and
the circulation in them is now perfect.
We made a trial run yesterday for
the first time, which showed that the
chemical reaction works on a large
scale as 1t did in The laboratory.
The ere which we purchased for
the purpose of making trial run, has
turned out to be- entirely different
from our ore. for the reason that it
contains an enormous amount of car
Donates of lime. etc. This has caused
us considerable trouble in getting
started However, we are now using
this ore
To-day the plant rs operating just
as we expected it would three weeks
ago; the delay in starting being due
to making minor mechanical changes
and to the time required in order to
become familiar with the apparatus.
I'VE mentioned in eur cable that
improved digesters were advisable,
but it may yet. turn out that these will
prove to be perfectly satisfactory.
We are now going to ~'''-4'tute
Corrosiron (acid-proof) piping for all
the present iron pipe. which change
does not amount to much. We shall
keep on operating as long as possible
with the present piping.
AT present we are making mangan-
csc nitrates from magnesium nitrates,
c-d have lust been advised bv phone,
this evening that the pIant has ope-
rated we'll today on this. AS you
know. the essence of the process is
the making of manganese nitrates.
Once we have made our supply of
nitrates they are used
over and over again. This cannot be
bought in the open market, and there
fore 1t will take little time to make
our supply.
Now that we know thak the pro.
cess works en- 3 large scale, Ii is I
simply 4 question Of mechanical ma
to obtain eaha ciiy. economy ,
efficiency. =
All Of the apparatus works salts |
factorily and no serious mistakes have |
been made. If We were to design ii
over again the only important change |
would be in the type of digesters.
These are only small portion of the |
plant. Even If we should substitute |
new ones later on it would be a mat. |
ter of $4,000 or $4,000 expense.
Assuring you that the process is
highly satisfactory and simple and |
past the experimental stage, we are.
Yours very truly,
MINERAL PRODUCTS 20.
