The design of a 45 m diameter elevated high density paste thickener in Siberia represents an example of an
application where paste and thickened tailings (P&TT) offers advantages in challenging environmental and
site conditions. The benefits of P&TT have been realised by an increasing number of mineral plants in the
world. Thickening tailings to paste can be an effective solution for deposition sites that are environmentally
sensitive. Conventional slurry deposition may be very expensive for some terrains, making paste relatively
economical. The use of this technology is not necessarily restricted from any particular geography or
climate. Thickened tailings technology was selected in part because the unique terrain made conventional
slurry deposition difficult and expensive. The high density thickener design was chosen because of the large
diameter necessary to accommodate the solids feed rate while producing a non-settling underflow (paste).
An elevated tank, as opposed to on-the-ground construction, was chosen because of considerations involving
climate-related construction issues. The purpose of this paper is to discuss the initial mechanical and
process design phase of the thickener, which will be installed and started up in 2010.
