  1. 1. Efficient modeling and control of crushing processes in minerals processing

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Marcus Johansson; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPGR; Comminution; Jaw crusher; Process control; Modeling; Dynamic modeling; Minerals processing;

    Abstract : Modeling and simulation is a tool to explore and increase the understanding of a phenomenon. This thesis focuses on developing models of crushers and equipment used in the mining industry. Specifically, the focus is on a branch of modeling called time dynamic modeling which is a model that gives an output as a function of time. READ MORE

  2. 2. Dynamic Modeling and Simulation of SAG Mill Circuits with Pebble Crushing

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Haijie Li; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic modeling; AG SAG mill; Fundamental modeling method; Data-driven modeling method; Pebble crushing; Cone crusher; Comminution process;

    Abstract : Grinding is one of the most energy-consuming processes in the mining industry. As a critical part of the comminution process, autogenous grinding (AG) or semi-autogenous grinding (SAG) mills are often used for primary grinding. READ MORE

  3. 3. Sustainable Water Quality Monitoring for Developing Countries in the Context of Mining : Monitoring systems and modelling

    University dissertation from Water Resources Engineering, Lund University

    Author : Clemencio Nhantumbo; Lund University.; Lunds universitet.; [2017-05-07]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Quality; Monitoring systems; Modelling; pH and alkalinity;

    Abstract : Mining, seen as a source of revenue in most developing countries, threatens seriously the environment. Mining impacts the water quality and one of the main problems of mining is acid mine drainage. Low pH and high concentration of heavy metals characterize acid mine drainage. READ MORE

  4. 4. Applying Design Analytics to Understand Engineering Change Request Information

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Ívar Örn Arnarsson; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Design Structure Matrix; Design Analytics; Engineering Change Request; Markov chain.; Product Development;

    Abstract : Large complex system development projects take several years to carry out. Such projects involve hundreds of engineers who develop tens of thousands of parts and millions of lines of code. During the course of a project, many design decisions often need to be changed due to the emergence of new information. READ MORE

  5. 5. Groundwater occurrence and risk of pollution in a mountain watershed of Nicaragua

    University dissertation from Engineering Geology, Lund University

    Author : Alfredo Mendoza; Lund University.; Lunds universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; electrical resistivity; surface water; springs; Nicaragua; Hydrogeology; groundwater; teknisk geografi; geographical and geological engineering; Hydrogeologi;

    Abstract : Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. READ MORE
