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

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

Pushing the Boundaries of Technology 4 Innovative Client SolutionsTenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

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

Pushing the Boundaries of Technology 4 Innovative Client SolutionsTenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

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
