Efficient performance of thickeners, clarifiers, washers, settlers
and classifiers is crucial to most mineral processing, hydrometallurgical
and water treatment operations. In our experience there is very
significant scope for improvement in most applications. The challenges
are to understand how to increase throughput, enhance performance
(overflow clarity, underflow density, flocculant usage), reduce
costs, improve operational stability. This can be achieved through
modifications to operating practice, retrofitting existing units
and the development of new design concepts.
Over the last fifteen years, a series of AMIRA P266 Improving Thickener
Technology projects, led by researchers from the AJ Parker Centre,
has considerably advanced the understanding of the fundamental processes
occurring within gravity thickeners, through the coupling of computational
fluid dynamics (CFD) modelling, physical modelling, experiments,
flocculation chemistry and extensive on-site measurements. As a
consequence of long-term support from the minerals industry, the
team now leads the world in identifying the key factors affecting
full-scale thickener performance and in modifying design and operating
conditions to realise improved performance for mineral processing
companies. The latest project, P266E, commenced in May 2005 and finished in May 2008, and
represents the fifth extension of the original project.
This website will provide a brief introduction to P266 for anyone
wishing to understand the project, how it operates and how to become
involved. Access to confidential project details is restricted to
sponsors. Passwords allow entry via the Sponsors Login section.
