  • Introduction to Process Water Recycling and Treatment in Mineral Processing
    Introduction to Process Water Recycling and Treatment in Mineral Processing Saara Hagnäs and Piia Suvio D.Eng., Product Manager and Director Water Treatment Solutions, Industrial Water Treatment Recorded: Feb 22 2018 37 mins
    Introducing a series of webinars on tailings dewatering, the third webinar will introduce water recycling and treatment in mineral processing. Each webinar will cover the topic from equipment to plant, taking a holistic view of the issues that enable and constrain the technology.

    In water recycling and treatment, we review the basics of water in mineral processing, and then expand the concept to water recycling and treatment in mineral processing plants.

    Water recycling in mineral processing plant can significantly increase the amount of water available for processing. Recycling of water leads to increase in constituents present in water, leading to accumulation of impurities that can impact the recovery of metal within the flotation and reverse flotation processes. Review on testing of the impact of certain impurities has been carried out and results will be presented. At the end of the webinar we will outline recommendations for process water treatment that can improve the recovery.
  • Introduction to tailings filtration and dry stacking in minerals processing
    Introduction to tailings filtration and dry stacking in minerals processing Toni Kuisma, Sales Manager, Tailings Solutions Recorded: Feb 15 2018 39 mins
    Introducing a series of webinars on tailings dewatering. The first webinar introduces thickening followed by tailings filtration and water treatment. Each webinar will cover the topic from equipment to plant, taking a holistic view of the issues that enable and constrain the technology.

    With tailings filtration and dry stacking, we briefly review the basics of solid-liquid separation from thickening and filtering, and then expand to dry material handling and dry stacking. It is essential to understand the material properties in order to optimize the compaction process, control the filling process, drain the tailings stack and plan its geometry, and control the stability of the tailings stack during its life cycle.

    Closing with a view from an operator’s perspective, including strategies for consistent performance and tips for avoiding process upsets.
  • Introduction to thickened tailings in minerals processing
    Introduction to thickened tailings in minerals processing Jason Palmer, Sales Director, Surface Tailings Solutions Recorded: Jan 24 2018 31 mins
    Introducing a series of webinars on tailings dewatering, the first webinar will introduce thickening followed by sessions on tailings filtration and water treatment. Each webinar will cover the topic from equipment to plant, taking a holistic view of the issues that enable and constrain the technology.

    With thickening, we review the basics of thickener operation and equipment selection, and then expand the concept to thickened tails transport and deposition. Controls and automation can significantly improve the performance of a thickener plant, keeping the outputs as close as possible to the design, maximizing water recovery and minimizing flocculant consumption. Closing with a view from an operator’s perspective, including strategies for consistent performance and tips for avoiding process upsets.
  • Mejores prácticas en las técnicas de muestreo
    Mejores prácticas en las técnicas de muestreo Tano Balbin, Gerente Técnico - Automation & Sampling Systems, Outotec Recorded: May 4 2017 58 mins
    Este webinar está enfocado en la importancia de los sistemas de muestreo en línea y su rol en los sistemas de análisis de muestras en las plantas de flotación.

    La instalación de las tuberías de manejo de muestras presentan características únicas que las diferencian de las tuberías convencionales de proceso (por ejemplo de agua de proceso o drenaje). La importancia de diseñar e instalar el sistema de muestreo es comúnmente descuidado, lo cual puede causar la pérdida de representatividad de las muestras obtenidas. Esto puede resultar en control de proceso inadecuado y terminar con una pérdida en la rentabilidad del proceso.

    El webinar cubrirá una discusión sobre cómo evitar estos problemas.
  • Process sampling practices
    Process sampling practices Janne Loimi, M.Sc., Application Specialist Slurry Sampling, Outotec Recorded: Apr 27 2017 37 mins
    This webinar will focus on the importance of a sampling system for an analyzer in a concentrator plant. Sample pipe routing and installation are more demanding than installation of process piping, e.g. water or sewer piping. The importance of designing and installing a sampling system is often overlooked causing a lack of representative samples. This results in poor process control and can decrease plant profitability. The webinar discusses how to overcome the above issues.
  • Del muestreo a la simulación de procesos de flotación
    Del muestreo a la simulación de procesos de flotación Rodrigo Grau, D.Sc., Principal Metallurgist Flotation, Outotec Recorded: Apr 11 2017 58 mins
    Después de haber presentado la teoría y conceptos fundamentales relacionados al muestreo, éste webinar se enfocará en las técnicas y procedimientos de muestreo, balance de masa, y simulación de una celda de flotación. Es importante comprender los elementos que rigen el rendimiento de la celda y bancos de flotación. Para evitar la interpretación errónea de resultados de una celda, y su extrapolación fuera de contexto, este webinar intentará explicar lo siguiente:
    •Procedimientos manuales de muestreo
    •Combinación de resultados con las herramientas de simulación HSC Sim
    •Optimización del banco de flotación para la mejoría de los resultados del proceso de flotación
  • From sampling to simulation of flotation process
    From sampling to simulation of flotation process Rodrigo Grau, D.Sc., Principal Metallurgist Flotation, Outotec Recorded: Apr 6 2017 56 mins
    After introducing the theory and fundamentals behind sampling, this webinar will focus on sampling procedures, mass balancing and simulation of a flotation bank. It is important to understand the performance of a bank and the individual cells. Overlooking individual cells may result in inaccurate and therefore misleading conclusions. To overcome this issue, the webinar aims to explain:
    •Manual sampling procedures
    •Combining results with the HSC simulation tool
    •Optimizing the flotation bank in order to improve plant output
