The Characterization of Ukrainian Volcanic Tuffs from the Khmelnytsky Region with the Theoretical Analysis of Their Application in Construction and Environmental Technologies.

(1) The mineral deposits are the base resources of materials used in building and environmental engineering applications, especially available locally. Two wells of volcanic tuff deposits in the Khmelnytsky region of Ukraine were investigated in this regard. (2) Physical-mechanical, chemical, and mineralogical analyses of the core samples were carried out.

Mineral Materials Coated with and Consisting of MnO-Characteristics and Application of Filter Media for Groundwater Treatment: A Review.

For groundwater treatment, the technologies involving oxidation on MnO filter bed are beneficial, common, and effectively used. The presence of MnO is the mutual feature of filter media, both MnO-coated mineral materials like quartz sand and gravel, chalcedonite, diatomite, glauconite, zeolite, or anthracite along with consisting of MnO manganese ores. This review is based on the analysis of research and review papers, commercial data sheets, and standards.
