Study and characterization of natural bentonite modified by Manganese Oxides
Dolinská, S. ; Schütz, T. ; Znamenáčková, I. ; Vaculíková, Lenka
The paper describes the preparation of new composite based on on relatively cheap natural materials from domestic deposits and synthetically prepared manganese oxides. The manganese oxides were precipitated on the surface of activated sodium bentonite particles.

Characterization of MSWI Bottom Ash and Assessment of Resource Recovery Potential
Šyc, Michal ; Kameníková, Petra ; Krausová, Aneta ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Bottom ash from municipal solid waste incineration contains valuable components that can be recycled as secondary materials, such as ferrous and non-ferrous metals, rare earth elements, glass etc. Metal-free mineral fraction is reusable in construction industry. The composition of bottom ash is highly dependent on the composition of incinerated waste but in average can be around 5–13 % ferrous metals, 2–5 % non-ferrous metals, 15–30 % glass and ceramics, 1–5 % unburned organics and 50–70 % mineral fraction. Several incineration plants in Europe are equipped with advanced systems for metals recovery, mostly based on magnetic separation of ferrous metals and separation of non-ferrous metals usually by eddy-current separators. To study the possibilities of bottom ash treatment in the Czech Republic it is necessary to obtain data about the bottom ash composition and evaluate the potential of resource recovery.
