Since the quality of ore bodies often decreases as rich resources get depleted, one trend is to process more slurry volume in one plant or module which leads to further increased vessel sizes for current and future projects.
These units have to be reliably designed to ensure that the whole plant can be reliably operated. Mixing tasks can be from solids suspension duties to demanding blending of non-Newtonian slurries, if for example increased solids concentrations have to be handled.
