“Product development never stops at Weir
Minerals. Over the past two decades our team of
engineers have developed advanced lining
technology for ultra-heavy duty applications, to
withstand the demands of high volume abrasive
materials,” states Switzer.
Weir Minerals is set to redefine hydrocyclone
efficiency again with the development of the new
Synertrex® monitoring system. The latest
technology in remote monitoring systems allows
users to obtain operational data in real time, to
ensure optimum performance and efficiency of
their mill circuit.
Today, there are more than 26,000 Cavex
hydrocyclones operating throughout the globe,
making up more than a quarter of world market
share. Every single one of these hydrocyclones is
backed by the extensive Weir Minerals service
team.
Diemme Filtration, a well known manufacturer
of filter press technology, will be exhibiting under
new ownership, Aqseptence Group. The
Aqseptence Group comprises companies from the
former Bilfinger Water Technologies Group
providing global experience and competences in
water treatment and separation technologies.
Diemme Filtration will showcase its new
GHT2500F filter press for concentrate and tailings
dewatering applications. Specifically designed
for large throughput applications, the GHT2500F
54 International Mining | SEPTEMBER 2016
provides up to 956 m2 of filtration area with 2.5 x
2.5 m filter plates in a ‘fast’ discharge
arrangement. With typical copper tailings, for
example, this translates to approximately 285 t/h
of dry filter cake.
The Diemme Filtration 2.5 m x 2.5 m filter plate
has been developed using modern design and
analysis tools such as CFD in order to improve
dewatering efficiency. As a result, very low
residual filter cake moistures are easily achieved.
Filter cakes are able to dewater to 15% moisture
very rapidly. With the addition of membrane
squeezing and/or cake air blow, even drier cakes
can be achieved.
Another significant breakthrough that Diemme
is releasing is ‘clothless’. filter technology.
Although not being displayed at MINExpo,
visitors can learn more about this new
technology at MINExpo. The company says “the
new technology is a potential game changer,
revolutionising the modern filter press system to
be more reliable and efficient by improving online time and reducing operating costs.”
TOMRA Sorting’s mining experts will be
available to explain the key advantages sensorbased sorting can bring to mining operations.
Although it is a relatively new technology in
mining, sensor-based sorting has the potential to
address some of the major challenges the
industry now faces: declining ore grades,
