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

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Frida Norlund; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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. LÄS MER

  4. 3. Online Metallurgical Mass Balance and Reconciliation

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Emil Andersson; [2021]
    Nyckelord :dynamic; froth flotation; mass balancing; mineral processing; reconciliation;

    Sammanfattning : In mineral processing, one of the most important and versatile separation methods is flotation. Flotation utilizes the different surface properties of the valuable minerals in the ore to separate them from the less valuable gangue material in the ore. Crushed and ground ore is mixed with water and fed into flotation tanks. LÄS MER

  5. 4. Exploring effects of hydrodynamic flotation variables on their respective metallurgical responses through laboratory scaling up

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Mohazzam Saeed; [2021]
    Nyckelord :;

    Sammanfattning : To meet the increasing demand for raw materials, higher throughput of mineral separation through froth flotation is becoming important. This higher throughput can be achieved by increasing the size of flotation equipment termed scaling up. LÄS MER

  7. 5. Machine Learning-based Quality Prediction in the Froth Flotation Process of Mining : Master’s Degree Thesis in Microdata Analysis

    Master-uppsats, Högskolan Dalarna/Mikrodataanalys

    Författare :Eric Kwame Osei; [2019]
    Nyckelord :Froth Flotation; Machine Learning; Random Forest; Multiple Linear Regression; Artificial Neural Network;

    Sammanfattning : In the iron ore mining fraternity, in order to achieve the desired quality in the froth flotation processing plant, stakeholders rely on conventional laboratory test technique which usually takes more than two hours to ascertain the two variables of interest. Such a substantial dead time makes it difficult to put the inherent stochastic nature of the plant system in steady-state. LÄS MER
