Weir and STM Minerals to accelerate sustainable mining
The Weir Group PLC (Weir), a global mining technology leader,
announces a new alliance with Swiss Tower Mills Minerals AG (STM)
in which Weir will market STM's innovative vertical stirred
grinding mills for coarse grinding applications world-wide.
Integrating vertical stirred grinding mills into Weir's minerals
processing flow sheet will provide customers substantial
improvements in throughput and energy efficiency, helping them to
meet their productivity and sustainability goals.
STM's vertical stirred grinding technology is well proven for
energy efficient comminution in the mining market with more than 80
units currently operating in the hard rock mineral processing
industry across the globe. It is used within the comminution
segment of the minerals processing circuit as part of a series of
crushing and grinding processes that create the fine particles from
which minerals can be extracted through floatation.
Comminution is one of the most energy intensive parts of the
mine, accounting for 25% of the final energy consumption of an
average mine site. Weir is already a leader in comminution
technologies, such as Enduron(R) HPGRs which are driving down
energy consumption by around 40% for customers.
This new alliance with STM takes things to the next level,
offering the mining and minerals industry a proven low energy
alternative to traditional high energy consuming tumbling mills.
Combining and integrating these energy efficient technologies into
a single, optimised flow sheet will deliver significant reductions
in energy use, driving down costs and carbon emissions.
Commenting on this technology alliance , Ricardo Garib, Weir
Minerals Divisional President said. "Weir and STM share the same
vision of enabling primary resource providers to produce resources
in the most sustainable manner. This is a perfect match of
best-in-class technology providers. Integrating STM mills with
Weir's comminution products, which includes Enduron(R) high
pressure grinding rolls (HPGRs) and Enduron(R) screens, will
improve throughput and help bring substantial reductions in carbon
emissions. This is a real win-win."
Fritz Moser, STM Chairman, said "Both the HPGR and the STM
vertical stirred mills provide significant energy savings compared
to conventional grinding technologies. Our new supply agreement
with Weir will enable us to fast track the roll out of an
innovative flow sheet using STM mills in conjunction with Weir's
In order to prove the most beneficial flow sheet for specific
projects, STM has already supplied two vertical test mills to the
Weir Minerals HPGR test facility in Venlo (Netherlands). Weir and
STM will be in the unique position to provide clients combined
energy efficient grinding test work of HPGR followed by STM's
vertical stirred mill.
Weir and STM share a passion for implementing Environmental,
Social and Governance (ESG) practices at every level of their
organisations. Together, they are proudly implementing sustainable
solutions that benefit the industry, the communities where they
operate and future generations.
