The tailings from coal mine instead of waste became applicable as enzyme supports
(European Federation of Biotechnology, 2023)
Some coal mines suffer from problem of having huge deposits of bentonite that they regard as undesirable, since bentonite can cause problem due to its swelling property. Instead of piling stacks of bentonite and regarding ...
Kristalografski podaci za aragonite iz donje-Meotskih laminita Đerdapa II / Crystallographical data for aragonites from the lower-Meotian laminites at Đerdap II
(Belgrade : Serbian Crystallographic Society, 2004)
In the framework of investigations of the white and gray laminas from the Lower-Meotian laminites at Djerdap II locality, it was established that they are composed from aragonite, Mg-calcite, quartz, feldspats and clay minerals.
Particle size distribution of iron ore sludge determined by using different methods and iron content by size class
(University of Banja Luka Faculty of Mining PrijedorMining Institute Belgrade Ltd, 2017)

Reuse of waste sulfur as a binding agent in concrete
(Association for Promotion of Holistic Approach to Environment, 2018)
Mainly due to the strict global environmental regulations regarding the oil and gas
refining processes, which limit the maximum quantity of sulfur in combustibles, the
availability of waste sulfur has been considerably ...
Flat band and photocatalytic activities of alumina/zirconia composite ceramics
(Srpsko keramičko društvo, 2022)
In the scope of this study mesoporous coupled alumina/zirconia composites were synthesized
via the sol-gel method, followed by heat treatment at 500°C, for 5h. The XRD pattern of
composites has shown that the addition ...
