1. The ore mined in the Schmalkalden ore mining district was produced by
working lodes on the outer zones bordering the Thueringer Wald in the
southwest. The ores contained an average of 28 to 34 percent Fe and 3
to 5 percent Mn. The main mines, including Klinge, Mommel and Stahlberg4were
equipper number of small hoisting machines (Arminius and others).
New ex s were made at Kohlberg, Vogelberg and at another point
located orth. In addition open work mining at the outcrops, 25X1
underg ng was done in the deeper portions. The lodes were primarily
of heavy spar (barium sulphate) and also some calc.spar. A central dressing
plant for all mines of the Schmalkalden district was recently put into operation
in Drusetala The ore was ground to 3-mm grain size and smaller. The ores are
separated for the processing into two types; one rich in iron and the other
one rich in heavy spar.
2. From the rich iron ore, a rich concentrate was separated in a magnetic
separation process and the remainder was treated in a wet mechanical process..
By sepaaratin~ the heavy spar, a second, less rich concentrate was obtained.
The concentrates contained anaarerage of 38 to 40 percent Fe.
3. In order to separate most of the heavy spar, the ores rich in heavy spar were
at first treated mechanically when wea,4The remaining mas4" were treated
An ore-dressing expert from East Germany confirmed that the central ore --
dressing plant in Drusetal was put into operation. He also stated that the
installation did not meet the requirements. The ores mined in the various pits
differed and had to be crushed to different grains'-in order to be dressed.
A second dressing installation would probably have to be established,
a:,lor the ores produced by the Stahlberg mine.

4. It was planned to replace the experimental unit by a main installation with
a daily capacity of 500 tons. After the completion of the new unit, the total.
capacity of the central dressing plant would amount to 800 tons per day which
would be adequ~te for the maximum output expected for the future in
Schmalkalden.

1. I comment- This figuaa is .n line with the earlier reported 1953
3a
plan figure fixed at 80,000 ti 901,000 tons of J.ron ore in the
Sc&,i al kalden Bezirk.
=Comment- This daily capacity would require a mine capacity of 240flO00 25X1
tons per year that is, a threefold increase of the present capacity.
Such an increase appears doubtful in view of the conditions prevailing
in the mine area..
