The MCmethod is finded as an important tool in environmental science and can beconsidered the most effective quantification approach for uncertainties.Uncertainty of data can be expressed through a definition of probabilitydistribution of that data (e.g. through standard deviation or variance). Thepresented case in this study is based on the example of the emission ofSO2, generated during energy production in Integrated Steel Power Plant(ISPP) in Kraków, Poland. MC simulation using software Crystal Ball®(CB), software, associated with Microsoft® Excel, was used for theuncertainties analysis. The MC approach for assessing parameteruncertainty is described. Analysed parameter (SO2,) performed in MCsimulation were assigned with log-normal distribution. Finally, the resultsobtained using MC simulation, after 10,000 runs, more reliable than thedeterministic approach, is presented in form of the frequency charts andsummary statistics. Thanks to uncertainty analysis, a final result is obtainedin the form of value range. The results of this study will encourage otherresearchers to consider this approach in their projects, and the results ofthis study will encourage other LCA researchers to consider the uncertaintyin their projects and bring closer to industrial application.","PeriodicalId":44414,"journal":{"name":"Inzynieria Mineralna-Journal of the Polish Mineral Engineering Society","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48530251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single stage grinding circuits have worked well inthe past as the designed criteria were achieved, however, mine productionhas increased sharply and deeper ores are being mined recently, so that thematerial composition of the run of mine ores have become more complicatedand are the ores become more difficult to be floated. As a result, processingcriteria of these plants become critically unstable and low. The study is toinvestigate the suitabity of two-stage grinding circuits for Lao Cai apatiteore type III. The report presents the results of the study on middlingsregrinding of hard floatable apatite samples of Bac Nhac Son flotation plant,where high loss of valuable apatite has occured due to low grindingperformance. Research results show that regrinding of all middlings to thefineness of 75% -0.04mm not only improves recovery but also help tostabilize technological operations and their processing criteria.

Its production, forthe most part, relies on the coal mining industry, thus resulting in a strongupward trend in mining volumes. Being geologically complex, Vietnamesemines are characterised by a complicated structure of their headings. Thelocal ventilation systems are also affected by there being very few automaticdams and an by increases in airflows delivered to the mine. For this reason,in order to analyse airflows and maintain the proper control of ventilationsystems, computer software is required. The article offers a comparison ofcomputer programs – Kazemaru, VentGraph and VentSim – as employedfor use in Vietnamese mines.
