Sorting of non-ferrous metals based on density, shape and composition
When processing bottom ash, non-ferrous metal concentrates are recovered, a mixture of non-ferrous metals and adherent bottom ash mineral. These non-ferrous metal concentrates need to undergo further processing in order to obtain pure metal streams, which can subsequently be sold as high-grade raw materials.
Aerinnova specialises in the recovery of various metals from non-ferrous metal concentrates. By applying innovative sorting techniques to specific fractions, Aerinnova succeeds in recovering non-ferrous metals with a high grade of purity. Aerinnova separates the various metals on the basis of density, shape and composition.
The separated metals such as aluminium, copper, brass and stainless steel are therefore ideal for supplying smelters. The residual bottom ash mineral can be used as a construction aggregate for making concrete or as a hardening material in road construction.
Aerinnova offers sustainable, cost-saving solutions whereby transparent work methods are paramount. This way we are able to offer our customers the highest possible value from the recovered metals.
Metals can be constantly reused as a raw material for new products. After the metals have been meticulously sorted, Aerinnova supplies the metals directly to customers in the metal industry in the Netherlands and abroad. Metal is remelted at various smelters back into raw materials for new products, which find their way back into the economy.
These recycling methods deliver CO2 savings of more than ninety percent compared to the mining of metals
