The impact of the porosity of limestones on the SO 2 sorption process has been shown. Limestone parameters, which should be assessed at the stage of qualification of raw material for raw material production, have also been determined. The research methods, which can be used to predict the reactivity of sorbent in industrial conditions at the stage of laboratory analysis, have been presented. Presented in this article studies on the reactivity of limestone terms of SO 2 were inspired by the problems of Polish power plants in meeting the SO 2 emission limits when using limestones as SO 2 sorbents in fluidized bed boilers and related to their low utilization and storage, and the high content of unreacted caO in the ash. the studies have been conducted for several years. in that time, been tested several hundred samples limestone of cretaceous (chalk), Jurassic, triassic, Devonian, and neogene (lacustrine chalk) age. the results of the study can contribute to the increased use of sorbent and thus increase the effi ciency of SO 2 capture in furnace conditions and, as a consequence, significantly reduce the amount of the combustion waste generated.","PeriodicalId":50416,"journal":{"name":"Gospodarka Surowcami Mineralnymi-Mineral Resources Management","volume":"42 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85833154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary aim of this study is to use remote sensing data to identify iron deposits and gossans located in kaman, Kırşehir region in the central part of Anatolia, Turkey. Capability of image processing techniques is proved to be highly useful to detect iron and gossan zones. landsat ETM+ was used to create remote sensing images with the purpose of enhancing iron and gossan detection by applying ArcMap image processing techniques. The methods used for mapping iron and gossan area are 3/1 band rationing, 3/5 : 1/3 : 5/7 color composite, third PC and PC4 : PC3 : PC2 as rgB which obtained result from standard Principal Component Analysis and third PC which obtained result from Developed selected Principal Component Analyses (Crosta Technique), respectively. Iron-rich or gossan zones were mapped through classification technique applied to obtained images. Iron and gossan content maps were designed as final products. These data were confirmed by field observations. It was observed that iron rich and gossan zones could be detected through remote sensing techniques to a great extent. This study shows that remote sensing techniques offer significant advantages to detect iron rich and gossan zones. It is necessary to confirm the iron deposites and gossan zones that have been detected for the time being through field observations.","PeriodicalId":50416,"journal":{"name":"Gospodarka Surowcami Mineralnymi-Mineral Resources Management","volume":"37 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75198570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They also contain a number of other elements, including iodine, bromine, boron, and strontium. The results of the examination of the chemical composition of groundwater from the Mesozoic formations (bromine, iodine, lithium, magnesium, and strontium content) of northern and central Poland were analyzed. The basic statistical parameters of the content of these elements (Br, i, Mg) in brines of the Triassic, Jurassic, and Cretaceous deposits and the content of lithium and strontium in waters of the entire Mesozoic formations were determined. in order to indicate aquifers that are the most suitable for the recovery of bromine, iodine, lithium, magnesium, and strontium, the relationship between concentrations and the depth of retention and dependencies between selected chemical components of these waters were analyzed. it has been found that the mineralization and concentrations of magnesium, bromine, and iodine increase with the age of aquifers, where these waters occur. Triassic waters are the most prospective for bromine and magnesium recovery among all analyzed aquifers. Furthermore, a relationship between the content of bromine, strontium, and magnesium has also been observed. The increase in the 20 Uliasz-Misiak and Winid 2018 / Gospodarka Surowcami Mineralnymi – Mineral Resources Management 34(2), 5–20 content of individual elements observed for lithium, strontium, and bromine with the increasing depth indicates a potential abundance of waters occurring at significant depths. The presented analysis is an approximation of the content of bromine, iodine, lithium, magnesium, and strontium; however, it may be the basis for further studies on the perspectives of using brines from the Mesozoic deposits of central and northern Poland as a source of chemical raw materials.

This is based on a combination of RGB images collected by a color industrial camera and a point cloud generated by a 3D ToF camera. Firstly, the mean-shift algorithm combined with the embedded confidence edge detection algorithm is used to segment the RGB ore image into different regions. Secondly, the effective ore regions are classified into large pieces of ore and ore piles consisting of a number of small pieces of ore. The method applied in the classification process is to embed the confidence into the edge detection algorithm which calculates edge distribution around ore regions. Finally, the RGB camera and the 3D ToF camera are calibrated and the camera matrix transformation of the two cameras is obtained. Point cloud fragments are then extracted according to the cross-calibration result. The geometric properties of the ore point cloud are then analysed in the subsequent procedure.

Jest to połączenie obrazów RGB zebranych przez kolorową kamerę przemysłową oraz chmury punktów wygenerowanej przez kamerę 3D ToF. Po pierwsze, algorytm zmiany średniej w połączeniu z wbudowanym algorytmem wykrywania krawędzi ufności służy do segmentacji obrazu rudy RGB na różne regiony. Po drugie, efektywne regiony rud są podzielone na złoża rudy o dużych rozmiarach i zwałowiska składające się z małej ilości rudy. Metodą stosowaną w procesie klasyfikacji jest określenie ufności w algorytmie wykrywania krawędzi, który oblicza rozkład krawędzi wokół regionów rudnych. Wreszcie, kamera RGB i kamera 3D ToF są skalibrowane i uzyskuje się transformację matrycy obu kamer. Następnie, fragmenty chmury punktów są wyodrębniane zgodnie z wynikiem kalibracji krzyżowej. W kolejnej procedurze przeanalizowano właściwości geometryczne chmury punktów rudy.","PeriodicalId":50416,"journal":{"name":"Gospodarka Surowcami Mineralnymi-Mineral Resources Management","volume":"18 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90037218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To accurately reproduce the seismic reflection covering the sub-Permian formations, seismic cross sections were interpreted based on effective reflection coefficients (ERC). In interpreting the results, reference was made to the results of studies of the area using other geophysical methods. The results of these studies made it possible to obtain new information on the geology and structure of the Paleozoic complex of the Radom-Lublin area and its relationships with the basement tectonics. The structural arrangement of Carboniferous and Devonian formations as well as older Silurian, Ordovician, and Cambrian series were recognized. Selected significant tectonic and lithological di-scontinuities and the nature and directions of their course were characterized. Special attention was given to regional tectonic zones: the Skrzynno Fault, the Ursynów-Kazimierz fault zone and the Kock zone. The use of ERC methodology made it possible to define the boundaries of lithostratigraphic units in Carboniferous, Devonian, and older formations. The obtained results can be used to assess hydrocarbon accumulation in the area under consideration.","PeriodicalId":50416,"journal":{"name":"Gospodarka Surowcami Mineralnymi-Mineral Resources Management","volume":"2000 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88296886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
