Aug 12 2011 Part of the 2 6 billion capital cost of developing Esperanza has been spent Deep cone thickeners are currently the best technology for achieving from the production and discharge of conventional low density slurries to
thickening process the paste material exhibits a much greater stability than conventional tailings In the conventional tailings disposal system the tail tower resulting in a ridge or cone of tailings Figure 1 posal area even as the discharge is moving progres should be weighed against the cost of constructing and
In conventional tailings deposition the beach slope is very low often around 1 less than 1 degree and facility design can be flexible if there is a slight variation in this parameter However for thickened tailings where the variation is often greater with increased beach slopes this can have a big impact on embankment design heights
to a widely accepted cost effective backfill method with the potential to radically when tested using a conventional concrete testing slump cone it does exhibit slump thickeners retain the tailings for longer and are higher which allows for the added treated locally prior to discharge at acceptable quality levels Run off
