1844. The section of the tunnel from Rothschönberg to
Halsbrücke was financed by the state. In the remaining sec-
tion of the tunnel, the mines concerned were responsible
for the construction of the tunnel themselves. For the con-
struction of the adit, seven auxiliary shafts (so-called light
holes) were sunk on the state side (fiscal part) in order to
drive the adit from them in two directions per light hole in
the opposite direction. In the case of counterdriving, the
tunnel is driven from two directions. The RSS today can
be identified as the main drainage structure of the Freiberg
mining district (Bayer, 1998). Water from the mine field
leaves the Freiberg gneiss and flows under agricultural land,
mainly through a phyllite environment. Above the level
of the RSS, the water is primarily oxygen-rich, but below
this level it is mainly characterized by only a process that
are chemical based. It is discovered that about one sixth of
the Zinc load in the Elbe comes from the Freiberg Reiche-
Zeche – which is also connected to the RSS. Consequently,
heavy metals from the flooded part of the Himmelfahrt dis-
covery mine together with organic contaminants also influ-
ence the RSS (Kluge et al., 1995 Kolitsch et al., 2001).
MATERIALS AND METHODS
A. Materials and Analytics
1) APTsorb
This is a commercial product and has achieved lots of suc-
cess in the waste water treatment industry. For this research
work it was able to provide a good control as it has proved
in many researches. These granules normally keep their
structure when wet and is adaptable hence making it able to
be sized into many forms. The media has also a big surface
area that is expected to help capture back suspended mate-
rials. In the Soudan Mine case, preceding small scale tests
shows that this media can remove both suspended and dis-
solved copper from the mine drainage (Eger et al., 2009).
2) Activated Coke
This material was produced by a Carbon consultancy com-
pany in Germany specialized in carbon services. For privacy
reasons, the name cannot be given. The mechanisms of
sorption for this product are chemical (ion-exchange, che-
misorption, complexation), physical (surface adsorption)
and the combination of adsorption-complexation
(American Peat Technologies, 2015)
3) Charred Fermentation Residue
This material was produced at an institute at the Freiberg
University of Mining and Technology but cannot be men-
tioned due to privacy reasons. The material is produced by
a heating process.
