The Seeker is looking for process to lower impurities in the making of primary Aluminium regardless of the incoming impurities in the raw materials. Specific impurities include Fe and Si as well as other micro-impurities (Ti, V, Na, Ga, B, Zn, Ca)

This Theoretical Challenge requires only a written proposal.


UC RUSAL is one of the major primary aluminium producers in the world by the reduction of alumina-cryolite melt. In Russia, the grades of primary aluminium depend on the content of aluminium and impurities in it, mainly - Fe and Si. The lower the content of these impurities, the higher the grade. The source of the other micro-impurities (Ti, V, Na, Ga, B, Zn, Ca) contained in primary aluminium produced are from the raw materials (e.g. alumina, coke, pitch, anodes, etc.) The Seeker would like processes to reduce any/all of these impurities that are not in use today. Solvers can work on any combination of these impurities for an award as one process is not likely to remove them all.

This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker. If multiple proposals meet all the Technical Requirements, the Seeker reserves the right to award only the solution which they believe is superior and cost effective. 

To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution. However, the Seeker will be willing to consider a licensing agreement for a partial award if exclusive IP cannot be transferred by the Solver.

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on January 18, 2018.

Late submissions will not be considered.



RUSAL is a leading, global aluminium producer and one of the world’s major producers of alumina. The company was founded in 2000 and became the global aluminium industry leader in 2007. RUSAL operates in 13 countries on 5 continents. The company employs over 61,000 people across the globe. RUSAL’s assets include 11 aluminium smelters, 11 alumina refineries, 8 bauxite mines, 3 aluminium powder plants, 2 silicon factories, 2 secondary aluminium plants, 4 foil mills, 2 cryolite and 1 cathode plants. The company’s current capacity means it is able to produce 4.2 million tonnes of aluminium, 11.5 million tonnes of alumina and 90 thousand tonnes of foil per annum. The company’s key sales markets are Europe, Russia and the CIS countries, North America, South-East Asia, Japan and Korea. The major end users are transport, construction and package industries. RUSAL’s main products are primary aluminium, aluminium alloys, foil and alumina. The company has access to vast resources of raw materials and provides for the entire production cycle – from bauxite mining to the production of alloys. This enables RUSAL to be operationally flexible and provide the highest quality of products.

What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is a Theoretical IP Transfer Challenge?

An InnoCentive Theoretical Challenge builds upon an idea but is not yet a proof of concept. A solution to a Theoretical Challenge will solidify the Solver's concept with detailed descriptions, specifications and requirements necessary to bringing a good idea closer to becoming an actual product or service.

This Challenge is a Theoretical-IP Transfer Challenge, meaning that Solvers must relinquish all rights to the Intellectual Property (IP) for which they are awarded. By contrast, Theoretical-Licensing means that the Seeker is requesting non-exclusive rights to use the winning solution. For these forms of a Theoretical Challenge, Solvers that do not win retain the rights to their solution after the evaluation period is complete. The Seeker retains no rights to any IP not awarded.
