AP60 - A breaktrough
in unsurpassed technology

AP60 technology, fabrication, aluminium smelter

At Rio Tinto Alcan, we’re proud to announce the latest generation of AP Technology™ pots built at industrial scale.

“The first phase of the AP60 plant, which will become the platform for future generations of AP Technology™ reduction cells, underscores Rio Tinto Alcan’s position as the world leader in aluminium smelting technologies. This proprietary technology has already evolved
from AP50 to AP60 since the project was first announced. It is the industry benchmark – the most cost-effective, energy-efficient and environmentally friendly smelting technology commercially available.”

Delivering a step change in productivity

The AP60 pot enables a step change in productivity by overcoming the challenges of very high amperage smelting technology. It‘s the result of years of continuous and focused efforts in R&D and pilot-scale operations. AP60 redefines the industry benchmark, providing us with the world’s most advanced and competitive smelter technology. It also reinforces the full economic cost leadership of our AP Technology™ series.

This enhanced performance technology delivers:

  • Lower capital expenditure per tonne of capacity
  • Improved labour productivity and reduced operating costs
  • Shorter construction, commissioning and start-up schedule

AP60 at the Arvida Smelter Technological Centre

The first phase of the Arvida Aluminium Smelter, AP60 Technology Centre consists of a 38 cell (31 first generation cells and 7 second general cells) plant with an annual production capacity of 60,000 tonnes of aluminium.

The smelter's first phase of 38 cells started in the second half of 2013. At the end of 2013, the smelter was running satisfactorily.

With the second generation of AP60 cells, the smelter’s total annual production capacity will reach 460,000 tonnes, powered by clean and renewable hydroelectricity.
