Copper Installations.
The Polish copper industry is relatively new, since there were no
copper mines within the pre war borders of Poland. The copper mining
which has been developed within the last few years has been concen-
trated in Silesia, which was annexed from Germany. The Sile3ian
copper installations are discussed in three 25X1
groups below:
a. Konrad Copper Mines and Flotation Installation.
The Konrad and Upadowa Copper Mines are located 90 kilometers to
the west of Wroclaw. The ore formation is sedimentary and the same
beds
as that of Mansfeld. The ore/lies in a stratum 1.5-1.8 meters thick
and slanted 6-12 degrees. The ores are obtained by underground mining.
Ore tenor is 0.8-1.0 percent, and the economical limit is 0.36.
The principal copper mineral is chalcopyrite. There are also bornite
and kalkosin? The hydraulic sand ramble3method is used. Underground

by trolley locomotives. In Konrad in the shafts and in Upadowa-Grodnice
ore extraction is done by descenders (sic). There are three shafts in
the Konrad mines which are disc sed below:
Konrad I shaft: This shaft, which is still in the process
of construction, will be 550 meters deep. It will be
equipped with two extraction installations of 1700 KW
for 2lt0 meters of depth, and a skip (sic) of six tors
for 550 meters of depth. When this shaft is completed,
it will be used for ore extraction, and the Konrad II
then
shaft, which is used for this purpose now, will/be used
for supplies. The extraction capacity of Konrad I shaft
will be l~,000 tons per day.
Konrad II shaft: This shaft, which is 180 meters deep,
is equipped with an extraction installation of 380 KW.
Konrad III shaft: The Konrad III has been equipped with
an extraction installation of 80 RW and is used as an
airing shaft and also in transporting mineral posts. In
the Upadowa and Grodziec mines, extraction is made by two
descenders making 12-degree angles.
The Konrad I and II and the Upadowa Grodziec are actually operated
as three independent mines, and the ores extracted from Konrad II
and Upadowa-Grodziec are carried to the flotation installation in
Konrad I. After the completing of traverba~' both mines will be
connected to the Konrad I mine.

Daily ore production after the amenagement-of the mineral is:?
Konrad I 1t, 000 tons
Upadowa-Grodziec 3,000 tons
Total 7,000 tons
Flotation Installation. Owing to the dispersal of the ore in tiny
particles and to the slime formation, flotation becomes very diffi-
cult and production is low. Although the capacity of the flotation
plant is 71000 tons per day, the plant works below capacity at the
present time because a satisfactory amount of ore cannot yet be
produced.
Ore is extracted from the mine in units of 300 mm apiece. These are
given to the ore silo in eight cups Csic). The ore~'at first ~ is
broken down to 35 mm by Bydgoskic Zaktady Maszin,
Polish brand konkas8r6with hammers which are powered by six Jeffrey-
type motors of 2 x 60 KGd the hourly capacity of which is 100 and200
tons. It is then broken into 12 mm in three USSR-made
Symons conic breakers (300 cm ~S). The ore which has been broken down
is carried to five refined ore silos the capacity of which is 800 tons.
The process of grinding is performed by USSR-made mills with balls which
are moved by five motors of 600 KW,~ 3200 x 3100 in size, the hourly
60
capacity of which is/~ tons. In these mills, which have 1~3 tons 120
mm steel ball charge and 20 cycles per minute, the ore ~ is ground
into 0.06 mm. The ball consumption per ore ton is 0.7.x. kilograms.

done by Humboldt-type flotation machines, the cell capacity of which
is 1,000 LT. First, at rough flotation (2 x 6 cellules) a rough
concentration of 3-1t percent was obtained, and this was given to
clean concentration cellules.
The remnants of the flotation nsa are ground into 80-200 percent mesh
in three Cylpebs mills with mill balls and rods of two compartments,
1500 x 5600 mm in size. Then being treated at the real flotation
(6 x 16 cellules), a middle concentration consisting of six percent
is obtained. The rough and the middle concentrations axe treated in
cleaning flotation machines (2xlo) and the final concentration con-
taining 12, 15 percent is obtained. The concentrated matter is first
filtered through by four USSR-made filters with drums and the dampness
is reduced to 20, 25 percent; later the dampness is reduced to 8-10
percent in turning dryers heated by gas, and this material is sent
to the melting place.
Reactors used at the Flotation are as follows:
Sodium ethyxanthate 1100 gr/ton ore
Pine oil 180 gr/ton ore
Phosocresol B 100 gr/ton ore
500 gr/ton concentrated
(as the flocculating agent to
the concentration thickener)
The copper mixture included in the remainder is 0.12 to 0.16, and the
ld is 75 percent.

b. Legnica Copper Smelting Plant.
The Legnica Copper Smelting Plants which is in the process of being
built, will be used for working concentrating copper.. The technical
procedure is the classical elting method. The briquettes
of 110 mm/and 70 mm which are produced by mi~d.ng coke dust into the
concentrated copper will contain the same amount of sulphur. The
briquettes thus produced will be melted in two WJ furnaces, andthe
material containing 38 percent Cu, 2!~ percent S, and 38 percent Fe
will be obtained. In WJ charge, coke of 16 percent will be used,
and to obtain one ton of material, appro~dmately three tons of concen-
trated copper will be melted. The WJ dross, which will contain 0.1~
percent copper,will be granulated and cast out (sic). The WJ furnace
gases, which will contain roughly 11.E percent, will be evaluated by
being }S used in heating the boilers at the energy power station (sic}.
By blowing the material in four Bierce-Smith type horizontal convertors,
one ton of blister copper will be obtained through 2.7 tons of material.
The convertor dross containing approximately 2 percent Cu will be
sent back to the WJ furnaces. The convertor gases which are estimated
to contain 5 percent S02 will be used in H2S0~ production. The blister
copper will be decanted in anode furnaces and moulded into anodes con-
taining 99.5 percent Cu.

.The concentrated copper/being produced, is melted in the Trzebinia
smelting plant located between Katowice and Krakow. After the tom-
pletion of the Legnica works, tdze Trzebinia smelting plant will be

c. Cranica Electrolytic Copper Refinery.
The Cranica Electrolytic Copper Refinery has a yearly capacity o
12,500 tons and will be enlarged to twice its size. Electrolytic
copper of 99.95 percent purity is produced here and moulded into
wire-bars by decanting the anodes which are produced at the melting
place. Electrolysis tanks made of concrete and lined with leaden
plates are 7~3xIt meters in size. In each tank 30 cathodes and 29
anodes are present. The cathodes last for six days and the anodes,
eighteen. The density of the current is 220 amp/m2 and the voltage
is 0.3-0.35. For each ton of copper, the energy consumption is
normally 1130 KWS. The consumption for the month of April 195? was
3b0 KWS. The temperature of the electrolyte is 55 degrees; it is
composed of the following materials:
