Conclusions
This study shows possibility of the natural adsorbents
utilisation for Cu removal from acid mine drainage. Turf
brush PEATSORB was the most efficient for copper removal
– decreasing of Cu concentration in AMD was about 54.5 %
under static conditions and 55.8 % in stirred sample during
s344

3 minutes. Based on experimental results we can state that
chosen adsorbents haven’t influenced pH increasing above 4
excepting active coal hence the Cu removal can be the result
of adsorption proces.
