It pays to talk to a specalist
The Delkor Ultrasep concept permits a very high rise
rate in the thickener and thus reduces the required
thickening area significantly, affording a far more cost-
effective thickening solution. The Ultrasep thickener has
no moving parts and uses patented internal baffles to
maximise compaction of the settles slurries.
It is used in the metallurgical and mineral processing
industry for mill circuit thickening, counter current
decantation, backfill and carbon-fines recovery,
dewatering and water recovery and slag treatment
The Delkor Conventional Thickener is often used where
the process requires minimal addition of reagents that
could affect downstream operations. The large area and
hence low rise rates allow particles to settle with little
or no flocculant addition. Though area requirements and
capital costs (CAPEX) are often higher, compared to a
High Rate design – long term running costs (OPEX) can
be lower.
The Delkor Pinned Bed Clarifier is a unique process
for hydrometallurgical plants where solution clarity is
important. Offering very low suspended solids counts
in the overflows, the clarifier regularly achieves clarities
of less than 50ppm solids, and even as low as 20ppm.

Typical applications include:
„ Cu / Co PLS clarification.
„ Gold Merrill Crowe clarification.
„ Uranium PLS clarification.
„ Au scrubber off gas clarification.
„ Zn PLS clarification.

Sedimentation is a cost effective method of increasing
the percentage of solids in a liquid - solid process. It
can be used in conjunction with filtration where the
pre-treatment of the slurry to a higher percentage of
solids will enhance and reduce the operational and
capital cost of the subsequent filtration stage, the
sedimentation step can also replace the filtration stage
when a high density slurry is sufficient for disposal or
subsequent processing stages.

The Delkor High Rate Thickener is a proven performer
in a variety of different applications including: minerals,
industrial, chemical, water treatment and waste water
industries. The reliability and performance of Delkor
thickeners means that they are well represented
throughout the world.
With a wealth of experience and a large database of
results, Tenova Delkor can provide accurate estimates
on sizing of a thickener for most applications. Bench
scale testing on representative samples can be carried
out at our numerous laboratories around the world and
we can also conduct site pilot tests, using high rate,
high density, Paste and Ultrasep models.

Tenova Delkor takes its knowledge and experience
of over 30 years providing thickeners for the mining
industry and applies it to the extreme mechanical and
process requirements needed when dealing with high
rheology underflows. The key driver for the use of
this technology is improved water recovery but there
are also numerous other advantages that minimise
environmental risks by reducing the footprint of tailings
dams and permitting backfill tailings emplacement.

With years of bench scale and site pilot testing and
full scale thickener experience, Tenova Delkor is able
to accurately and quickly ascertain the type, geometry
and number of thickeners for a particular application.
Designs can vary from large diameters with standard
side walls and deep cones to smaller diameter, very
high sidewalls and deep cones for production of paste.
Delkor thickeners have been used on a variety of different materials in a number of different industries.
