• An EKF observer to estimate semi-autogenous grinding mill

    A non-linear observer model of a semi-autogenous grinding mill is developed. The observer model distin-guishes between the volumetric hold-up of water solids and the grinding media in the mill. Solids refer to all ore small enough to discharge through the end-discharge grate and grinding media refers to the rocks and steel balls.
