Thickeners - Pushing Boundaries?

Thickeners are a fairly mature product.

Overall design has remained reasonably constant for the last 30 years.

What innovative steps can be taken?
What Do Customers Want?




Higher underflow densities.
Reduced flocculant consumption.
On time delivery with good quality
Larger equipment
Scope for Innovation?

Customer Request

Tenova Delkor was sole sourced for the thickener package for the Nui Phao Project, Vietnam

In order to improve delivery and reduce the plant area, Nui Phao asked if elevated steel tanks for
the 55m and 60m thickeners were possible

First tank bigger than 50m

The Tenova Delkor team developed a detailed design using FEA software

The design was submitted to Jacobs and after a number of design iterations related to seismic,
loading and footing positions a final tender was submitted

In August 2011 – Tenova Delkor was awarded the project

From FEA to Site Installed
Finite Element Analysis

From the order in August 2011 – the tank was
fabricated, delivered and installed by December
2012

The unit was successfully hot commissioned in
June 2013

Ongoing Success

Due to the successful completion of this
project both Tenova Delkor clients as well as
staff are know confident in the companies
ability to deliver these units.

Clients in both Canada and India have placed
orders for similar sized thickener tanks on the
back of this order and Tenova Delkor is seen
as being at the forefront of thickener tank
design.

The local office provided the Ambatovy mine
in Madagascar with the option of an 80m free
standing tank for their second ore thickener –
which gave them the opportunity to compare
against the in-ground concrete design they
had used previously.

Other Developments

Large thickener tanks are but one example
of Tenova Delkor innovation

The quest for higher underflow densities
has lead to the development and patenting
of a shear thinning system

We have also developed the most effective
internal dilution system in the market that
will markedly reduce flocculant
consumption, improve thickener control and
ultimately give a higher underflow density
