dc.description.abstract	Tato studie se zaměřuje na získávání cínu a solidifikaci kalu ze zrcadlového broušení. K extrakci cínu z kalu se používají roztoky hydroxidů o různé koncentraci (0,1 – 10M). Kal je dále upravován technikou stabilizace a solidifikace s použitím běžného portlandského cementu jako pojiva. Vzorky byly hodnoceny pomocí rentgenové fluorescenční analýzy, vyluhovacích zkoušek a pevnosti v tlaku v případě solidifikovaných vzorků. Výsledky ukázaly, že v případě extrakce v 10M hydroxidu sodném bylo získáno téměř 57 % cínu jako sraženina. Optimální obsah pro solidifikaci kalu byl obsah 50 % cementu. Dále byl hodnocen vliv přídavku aktivního uhlí do solidifikačních směsí. Závěrem lze říct, že kal ze zrcadlového broušení se ukázal jako vhodný pro získávání cínu a solidifikovaný odpad lze považovat za odpad, který není nebezpečný.	cs
dc.description.abstract	This study aims on tin recovery and solidification of mirror-grinding sludge. To extract tin from sludge, different hydroxide solutions (0.1 - 10M) are used. The sludge is also treated using the stabilization and solidification technique using ordinary Portland cement as a binder. Samples were evaluated using x-ray fluorescence analysis, leaching tests and compressive strength in the case of solidified samples. The results showed that nearly 57 % of tin was recovered as a precipitate in case of extraction in 10M sodium hydroxide. The 50 % of ordinary Portland cement was the optimal content for the solidification of sludge. The influence of active carbon addition into solidification mixtures was also evaluated. In conclusion, the mirror-grinding sludge was suitable for tin recovery, and its solidification resulted in non-hazardous waste. © 2022 Czech Environment Management Center. All rights reserved.	en
