Green soil stabilizer pilot

The industrial extraction of aluminium oxide from bauxite ore, leads also to the production of the Bauxite Residue by-product, which contains the remaining minerals of the bauxite ore. Under the RemovAl H2020 project, Acciona and Aughinish Alumina refinery have demonstrated a technology to recover Bauxite Residue and other industrial residues such as Ground Granulated Blast Furnace Slag (residue from iron production) and Pulverised Fly Ash (residue from coal combustion) to produce high performance road sublayer.  This technology was engineered to re-use large quantity of bauxite residue, which is widely available in all countries where alumina is produced, to get to […]

De-alkanization pilot

As part of the RemovAL H2020 project, Aughinish has demonstrated a technology to reduce the total soda in Bauxite Residue (BR) to less than 0.5% on a Na2O basis. The technology required the reaction of the BR with calcium hydroxide under specific conditions and time to produce the very low soda material, also termed Dealkalised BR. To-date, samples of the treated residue have been shipped to 12 different companies and research institutions to investigate its use as a supplementary cementitious material (SCM), as well as in the production of geopolymers, dense monoliths and slip-bricks. The pilot plant has demonstrated that […]

Pilot Scale Bauxite Residue treatment for holistic utilization

The industrial extraction of aluminium oxide from bauxite ore, leads also to the production of the Bauxite Residue by-product, which contains the remaining minerals of the bauxite ore. Under the RemovAl H2020 project, #MYTILINEOS has demonstrated a technology to recover metallic iron and slag from the Bauxite Residue in an Electric Arc Furnace. The slag of the process, which is usually a metallurgical waste stream, has been chemically designed to be usable in numerous applications ranging from use as raw material for aluminium and scandium oxide extraction to clinker substitute for cement production. Thus, this tunable process allows for the […]

RemovAL, explained

The RemovAL project has the ambition to remove the waste streams from the primary Aluminum production in Europe! RemovAL overcomes the barriers of economic viability by pooling together and integrating proposed stand-alone solutions, while adhering to the following principles: Treat waste with waste Develop marketable products Recover valuable critical metals Customise the solution to the industrial ecosystem of each alumina plant
