  1. 1. Comparison of Level Control Strategies for a Flotation Series in the Mining Industry

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Frida Norlund; [2022]
    Keywords : Technology and Engineering;

    Abstract : Separating valuable minerals from waste rock is an important step in the production of metals. This is for copper ore done through a process called flotation. A flotation series consists of tank cells in series where the minerals are collected in a froth on top of the cells. READ MORE

  3. 2. Evaluating rougher-scavenger flotation circuits using geometallurgical particle-based approach

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Luis Enrique Huaman Mamani; [2020]
    Keywords : Particle tracking; Flotation; Process mineralogy; Mineral liberation; Mass balance; Reconciliation;

    Abstract : The major challenges currently facing the mining industry are related to the growing trend to deal with deeper ore bodies and consequently increasing complex ores. This has led to the development of new approaches to tackle incoming issues by integrating different parts of the value chain in order to offer appropriate solutions. READ MORE

  4. 3. Potential Use of Oxygen Depleted Air In Nickel Sulphide Flotation

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Bianca Henriques Leal Andrade; [2018]
    Keywords : ;

    Abstract : Copper-nickel low grade ore deposits normally have complex mineralogy and process behaviour. Implementing an optimum process that is able to recover all the valuable minerals efficiently is challenging. One concentration strategy in mineral processing of copper-nickel sulphide ores is stage-wise flotation. READ MORE

  5. 4. Modeling and control of mill discharge pumps in the Aitik copper mine

    University essay from Umeå universitet/Institutionen för fysik

    Author : Tomas Vikner; [2018]
    Keywords : ;

    Abstract : Boliden Aitik is the largest open-pit copper mine in Sweden, and during 2017, more than 39 million tonnes of ore was processed into concentrated copper, silver and gold. The distributed control system 800xA is provided by ABB, and this is what the operators use for process monitoring and control. READ MORE

  6. 5. Modeling and Control of Lime Addition in a Flotation Process

    University essay from Linköpings universitet/Reglerteknik

    Author : Rasmus Tammia; [2017]
    Keywords : Automatic Control; Mineral Processing; Flotation Process; pH Control; System Identification; Modeling; Signal Processing;

    Abstract : Flotation is an important and versatile mineral processing technique that is used to separate hydrophobic materials from hydrophilic. This technique makes it possible to mine complex ores that otherwise would have been regarded as uneconomic and non-beneficial. In this case flotation is used to separate copper from the unwanted gangue. READ MORE
