Abstract

Se describen un metodo y un sistema para medir las propiedades de la fase de pasta de una celda de flotacion e incluye al menos parcialmente sumergir una sonda dentro de la fase de pasta de la celda de flotacion. La sonda incluye una camara, una fuente de luz y un panel de visualizacion en un extremo operativo de la sonda. El panel de visualizacion se coloca en angulo con respecto a la vertical y la camara se usa para obtener imagenes intermitentes de la fase de pasta a traves del panel de visualizacion y sometida a iluminacion proveniente de la fuente de luz.A method and system are described for measuring the properties of the paste phase of a flotation cell and includes at least partially immersing a probe into the paste phase of the flotation cell. The probe includes a camera, a light source, and a display panel at an operating end of the probe. The display panel is positioned at an angle to the vertical and the camera is used to obtain intermittent images of the pasta phase through the display panel and subjected to illumination from the light source.
