In 1999 the ACG initiated the series of international seminars on paste and thickened tailings. This influential and respected annual
event continues to provide a valuable forum for international tailings and mine waste practitioners to explore, learn and share
advances in paste and thickened tailings and, increasingly important, water conservation and environmental stewardship.
Richard Jewell and the ACG team look forward to welcoming many previous seminar attendees and those interested to learn more
about mine waste management to the 18th International Seminar on Paste and Thickened Tailings. The last time that the event was
held in Australia was Paste 2011, Perth. In 2014 it was held in Canada.

Slurry Rheology Fundamentals for Slurries and Pastes Short Course
3 May 2014 | Pullman Cairns International Hotel | Australia
“Integral to process plant design is identification of the slurry system
operating window 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 COURSE
An understanding of slurry and paste rheology or fluid flow,
dewatering including thickening and filtration and surface chemistry/
rheology interrelationships is fundamental to slurry system design,
operation and risk management.
Although the situation has improved over recent years, investment
into understanding slurry fundamentals is still often insufficient to
mitigate against the risk of under or over design and poor operating
performance.
The course will focus on identifying what information is required, how
to interpret measured data and how to apply to new system design
and existing operations.
Attendees 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 course will outline how to apply rheology and surface chemistry
for pipeline transport and thickening equipment selection and optimal
control and operation.

An Introduction to the Design of High Density Tailings Disposal
Pipelines Short Course 4 May 2014 | Pullman Cairns International Hotel | Australia
COURSE OVERVIEW AND OBJECTIVE
The objective of the course is to provide attendees with an overview of the broad design principles of high concentration slurry pipelines used for
the disposal of paste and thickened tailings.
The course includes a brief overview of the hydraulic design of pump and pipeline systems by considering the interaction of the pipeline system
and pump performance curves when pumping water. This provides the basis for understanding the differences between Newtonian and
non-Newtonian pipeline systems. The concept of rheology and its importance in pump and pipeline design will be discussed, and the
implications of pumping viscous slurries on equipment selection will be presented.
On completion of the one day course, delegates will have an appreciation of the requirements for the design of high density tailings slurry
pipelines.
TARGET AUDIENCE
The course is aimed at mining professionals who have limited exposure to the design of slurry pipelines and wish to obtain further understanding
of the basic design principles required for high density pumping systems.

Mine Backfill System Design, Operation and Management Short Course
4 May 2014 | Pullman Cairns International Hotel | Australia
COURSE OVERVIEW AND OBJECTIVE
TARGET AUDIENCE
Backfill is seldom recognised as a critical part of the mining cycle until it is too late. Poor
design, inadequate comprehension of the materials, or under-sizing of the entire system
can lead to unreliable fill delivery, or worse – no backfill placement at all.
Starting with the selection of backfill method, through testing and design, a successful
project is one that includes structural and environmental considerations, plus life cycle
costs of the backfill material and the system itself.
A sound understanding of the material properties and proven design fundamentals
ensure a mine’s backfill system will be reliable and cost effective. This one day course will
briefly touch on backfill methods, and then focus on paste fill and the important
relationships between system design, operation and management.
The course objective is to provide participants with an overview of the fundamentals to
be considered when effectively sizing, designing and operating mine paste fill systems.
Particular attention is paid to the implementation and management of a ‘best practice’
operation. On completion of the one day course, delegates will have an appreciation of
the requirements for the design and operation of a safe and reliable paste backfill system.
The course is aimed at mining professionals who have limited
exposure to the design of paste backfill systems, or may be
operating a system now and wish to obtain further understanding
of the basic design principles.
