An analysis of the chemistry, mineralogy and texture of waste dolomite powder used to identify its potential application in industry
(Wydawnictwa AGH, 2015) Gruszecka-Kosowska, Agnieszka; Wdowin, Magdalena; Kosowski, Tomasz; Klimek, Agnieszka
In this work, characterization of dolomite powder was carried out in order to specify possible industrial applications. After the technological use of dolomite aggregates, the remaining fine powder becomes a waste. Raw and calcined powder samples were subject to mineralogical, textural and chemical studies involving leaching tests. The results of the calcination process indicate that the carbonate minerals present in the material sample undergo complete decomposition to form oxides. After the calcination, the material is practically non-porous, and its surface area is more than five times lower than that of the raw material. However, due to the high content of calcia in the calcined sample (CaO > 45% wt.), the material cannot be used as an additive in cement. The leaching tests showed that the concentration of metals released from the dolomite powder is low enough to classify the material as hazardous waste according to the TCLP test. Moreover, the concentration of metals that can get into the environment does not exceed permissible values as set by Polish law. Thus, it is recommended and justified to carry out detailed tests for the purpose of environmental protection, i.e. wet flue gas desulfurization, heavy metals absorption, and $CO_2$ capture.

(2015) Fijał, Jerzy; Gonet, Andrzej; Jamrozik, Aleksandra
This investigations were carried out on different spent water-based muds, collected in drillings in various parts of Poland. The combined study methods included structural and phase investigations (X-ray diffractometry, infrared FTIR spectroscopy, scanning electron microscopy) and instrumental chemical determinations. The results characterize mineral and phase composition of the samples, their microstructure and chemical composition. The authors focused on the specific nature of polymer-clay complexes, which in drilling mud systems have the form of delaminated or exfoliated organic-clay polymer nanocomposites that control properties of such waste materials. Detailed recognition of properties chemistry, mineral and phase composition, microstructure of spent drilling muds have a fundamental meaning for studies on the management of these materials in the natural environmental.

Wermikulit jest minerałem ilastym z grupy hydromik. Wermikulit należy do krzemianów warstwowych o typie budowy 2:1. Ten minerał należy do sorbentów ilastych. Sorbenty mineralne charakteryzują się zdolnością do wymiany jonowej, przede wszystkim kationów. Często wermikulit jest modyfikowany poprzez ekspandowanie w celu uzyskania poszerzenia jego właściwości. Wermikulit powstaje w procesach naturalnego wietrzenia biotytu, flogopitu, niektórych chlorytów oraz innych krzemianów zasobnych w magnez. Ten minerał ma szerokie zastosowanie, a najważniejsze jest w ochronie środowiska. Wyniki dyfraktogramu wskazują na to, że badana próbka jest minerałem mieszanopakietowym wermikulit/illit. Maksymalna wielkość sorpcji wermikulitu dla ołowiu wynosi około 500 mmol Pb/kg, a dla kadmu wynosi około 300 mmol Cd/kg.

(Wydawnictwa AGH, 2023) Nowicki, Dawid; Suder-Dębska, Katarzyna; Czajka, Ireneusz
More and more attention is being paid to the impact of industry on the environment and people’s surroundings. One type of pollution is the noise that is generated by technological apparatus. It is necessary to develop new tools that will be able to survey noise in large industrial areas. This paper presents a concept of using unmanned aerial vehicles to generate acoustic maps of a surveyed area. One of the tools that is required for this purpose is aerial photogrammetry, which is used to generate a numerical terrain model from a series of photographs. The methodology and results of the simulation study of the effect of the data-acquisition-process parameters (flight altitude and transverse and longitudinal overlay levels of images) on the quality of the generated numerical terrain model and the generating time are presented in this paper.
