Optimising the Tantalum Recycling Process through Conditioning of Raw Materials, Process Automation and Material Logistics


The project OpTaRec proposes the upscaling of innovative solutions for the conditioning of secondary raw materials, the implementation of innovative process automation and the application of efficient material logistic concepts. Through the upscale of the solutions elaborated within the three activity fields and their interplay (fully integrated process concept), the consortium targets the following objectives: increase of the resource efficiency (decrease of yield losses of up to 2% – 3% along the entire production chain, decrease of energy consumption of up to 20%), advancement of the cost efficiency (savings of ~1 Euro/kg on production costs), improvement of the product quality (improvement of the metal selection process and recovery), reduction of the impact on the environment through the decrease of material loss emissions and developing innovative solutions for processing other recycling materials that cannot be processed technically or economically so far.
