Tailings pipelines for Mine Waste Management Ausenco
Challenging economic conditions and increasingly strict environmental regulations demand tailings pipeline systems that travel longer distances, at higher concentrations and with longer design lives Our solutions include gravity flow, open channel flow, energy dissipation, multiple pumps in series, and thickened paste disposalo pipeline flow behaviour modelling, friction loss calculation and pipe diameter selection This paper covers the following aspects of thickened and paste tailings design: o centrifugal pump performance, o hydraulic design including hydraulic grade line development, pump ThickenedandPasteTailingsPipelineSystems: Design Procedure seminars on paste and thickened tailings (PTT) initiated by the ACG in 1999 It reflects the developing maturity of PTT management Paste 2018 seeks to explore the considerations needed to raise the mining industry leaders’ awareness of how important environmental stewardship, with regard to their tailingsPASTE AND THICKENED TAILINGS Paste 2018

However, thickened and paste tailings storage will become more popular particularly as the day to day management aspects are not as intense as conventional storage techniques As well as the advantages of thickened tailings storage as discussed in the thickened tailings section, some additional advantages of paste disposal are:Like with thickened and paste tailings, the mechanical dewatering process compared to conventional slurry deposition increases costs Producing wet and dry cake further increases this cost particularly if high throughputs are required However, some of the many advantages to using dry stacking of tailings Tailingsfo Dry Stacking of tailingsAusenco’s tailings transport solutions include gravity flow, openchannel flow, energy dissipation, multiple pumps in series, and thickened paste disposal We also offer our clients expertise in pipeline SCADA and telecommunications systemsTailings Management Metal Recovery Ausenco
