This seminar is the twenty-first in the series of international seminars on paste and thickened tailings (P&TT) initiated by the ACG in 1999. It reflects the developing maturity of P&TT 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 tailings facilities, is to long-term industry sustainability.

Over the past decade, the potential benefits to be gained from adopting thickened tailings technology on mining operations have become widely accepted, and there would be few mine feasibility studies presently undertaken that do not include this as an option to be evaluated.

Very interestingly, a number of operations are now retrofitting their plants and tailings storages from conventional to thickened technology. The reason for this is the increase in the mass of tailings that can be accommodated on a given footprint and, more importantly, the greater volume of water that can be recovered for re-use in the plant in arid areas.

“Integral to process plant design is identification of the slurry system operating win-dow that allows increased throughput while decreasing capital and operating costs.

For any system involving thickening or paste production, understanding the material rheological characteristics is prerequisite to identifying this window and successful,

optimal and reliable operation”.

About the Workshop

An understanding of slurry and paste rheology or fluid flow, dewatering including thickening and filtration and surface chemistry/rheology inter-relationships is fundamental to slurry system design, optimal operation and risk management.

Investment into understanding slurry fundamentals is often insufficient to mitigate against the risk of under- or over-design and poor operating performance.

The workshop will focus on identifying what information is required, how to interpret measured data and how to apply this to new system design and existing operations.

You will learn about slurry physical and chemical properties, how flow properties or rheology are measured and how to meaningfully interpret rheological data for viscosity, yield stress, time dependence and dewatering information.

The workshop will outline how to apply rheology and surface chemistry for pipeline transport and thickening equipment selection and optimal control and operation.

TSThickening of mine tailings is now going beyond

the use of large, deep thickeners and addressing a new challenge – filtration of tailings to produce a low water content material that should pose much lower environmental and safety risks than most conventional TSFs.

Tailings filtration provides many potential benefits, including improved water recovery and the ability to deposit and compact the filtered tailings to form a stable, engineered landform.

However, there are also many concerns and potential pitfalls in adopting a filtered tailings management system, including high capital costs, equipment reliability, clogging of filter cloths, appropriate wash systems and optimisation of placement techniques.

Although in the past it has been considered unachievable, large-volume filtered tailings operations are beginning to emerge and there are already a number of operational facilities dealing with medium volume (to the order of 20 ktonne/day) throughputs.

Given the increasing scrutiny of the mining industry and its relatively poor record with regards to mine tailings management, increased requirements to minimise water usage (often accompanied by very high costs of water) and the need to demonstrate achievable long-term closure strategies, it is likely that the option of a filtered tailings system will need to be considered in many operations in future.

It has therefore been decided to dedicate a short course to this topic to provide practitioners and decision-makers with as much information as possible, as early as possible.

Drawing on experiences from a number of operational filtered tailings facilities, the short course will discuss available technologies, appropriate test programmes to determine relevant design parameters, operational challenges and cost comparisons.

About the Short Course

IS THE FUTURE FILTERED? PASTE AND THICKENED TAILINGS SHORT COURSETUESDAY 10 APRIL 2018 | RENDEZVOUS HOTEL PERTH SCARBOROUGH, SCARBOROUGH, WESTERN AUSTRALIA

Designers, consultants, owners and operators, mine planners, regulators and researchers would all benefit from attending this short course, which will provide a valuable opportunity to examine a rapidly growing technology that is likely to see increased adoption in the future.

PASTE 2018 SITE VISIT – ALCOA OF AUSTRALIA’S KWINANA BAUXITE RESIDUE STORAGE AREASATURDAY 14 APRIL 2018 | KWINANA BAUXITE RESIDUE STORAGE AREA, WESTERN AUSTRALIA

Alcoa commissioned an innovative technology known as residue filtration at Kwinana Refinery in 2016. With this technology, bauxite residue generated from the alumina refining process is forced through very large filters that squeeze out the waste water, which is recycled in the refining process. The filtered material allows for more efficient utilisation of existing residue areas, deferring the need to build new areas. The water recovered from filtration also significantly reduces the refinery’s freshwater needs. Alcoa continues to evaluate the potential use of this technology at other refineries around the world with construction of a filtration plant at the company’s Pinjarra Refinery in Western Australia’s Peel region underway.

The ACG thanks Alcoa of Australia for freely donating their time and resources to host this visit. This half-day site visit includes return transport and lunch in Fremantle.

The site visit is fully subscribed.

Since 2005, the ACG has published conference papers across the geotechnical mining spectrum, including: underground and open pit mining, paste and thickened tailings and mine closure. The repository aims to provide the mining geomechanics fraternity with open access to peer-reviewed conference proceedings that may assist readers to maintain and develop their skills, knowledge and capabilities.

Paste 2018 Seminar papers will be freely available online through the ACG Online Repository at papers.acg.uwa.edu.au. A printed, colour, softbound book will be available for purchase when registering for the event.
