Stochastic modelling of beach profiles including the influence of thickener performance

It is generally well accepted that in the design and operation of thickened tailings storages, ‘better’ thickener performance will improve the beach profile, and thereby enhance the overall performance of the stack.

Expert opinion on risks to the long-term viability of residential recycled water schemes: An Australian study

The water sector needs to make efﬁcient and prudent investment decisions by carefully considering the long-term viability of water infrastructure projects. To support the assessment and planning of residential recycled water schemes in Australia, we have sought to clarify scheme objectives and to further deﬁne the array of critical risks that can impact the long-term viability of schemes.

An Innovative Approach to Determine Particle Size Distribution for Rockfill Material

Particle characterisation like size distribution and shape can greatly affect the mechanical behaviour of granular materials, and is closely related to the economics for engineering projects. For rockfill material in embankment dam construction, the particle size distribution (PSD) is fundamental to the design, quality control and numerical modelling.

SPH modelling of multi-ﬂuid lock-exchange over and within porous media

Multi-ﬂuid ﬂow over and within porous media occurs frequently in nature and plays an important role in engineering applications. The modeling of these ﬂows and validation against experimental or ﬁeld observations have not been largely conducted in literature. An explicit numerical scheme for incompressible ﬂuid using Smoothed Particle Hydrodynamics (EISPH) was employed and solved using two integration algorithms.

Thickener performance variability: underflow solids concentration and flowrate

The operational fluctuations of tailings thickeners have the potential to cause significant impacts on the tailings transport system and the tailings deposition at a tailings storage facility (TSF).

Why do residential recycled water schemes fail? A comprehensive review of risk factors and impact on objectives

In Australia, recycled water schemes have been implemented in residential developments to contribute to sustainable urban development, improve water supply security and reduce pollutant discharges to the environment. A proportion of these schemes, however, have been decommissioned well before the end of their design life which raises questions about the adequacy of the risk assessment and management practices adopted for recycled water schemes.

Open channel transportation of thickened tailings

The mining industry is moving towards thickened tailings with higher density than conventional operations. As a result, tailings transportation is more challenging due to the material’s tendency to exhibit non‐Newtonian behaviour at high solid concentration.

Chuquicamata full-scale field deposition trial

A large-scale field deposition trial was carried out at the Chuquimata mines Talabre Tailings Storage Facility (TSF) in Chile to study the achievable beach sloop with the current tailings in the absence id further thickening. The tailings received art the Talabre TSF are a mix of tailings from two different operating mines; Chuquimata (CH) and Ministro Hales (MH).

Stochastic beach profile modelling

Modelling of a tailings beach using a time series of thickener output (flow rate and solids concentration) was first reported by Fitton et al. (2007). Seddon and Fitton (2011) presented statistical data on the performance of thickeners, and showed that the observed concave shape in tailings beaches could be adequately explained by this variability.

Paste & Thickened tailings – myth busting and clarification

It is the contention of this paper that there remains considerable confusion regarding the mechanisms and benefits of thickened tailings schemes. This paper will attempt to clarify some of these issues.
