2. METHODOLOGY
2.1. Materials The BA fraction considered in this study is one of several fractions produced after a prior treatment process [40] : 1. Weathering for 3-6 months, reducing the materials heavy metals leaching and reactivity. 2. Dry separation: extracting large metal fractions by overhead magnet, impact crushing reducing the particle size to < 40 mm, and ballistic separation into a 0-2 mm and 2-40 mm fraction. 3. Dry separation and recovery of metals from the 2-40 mm fraction: secondary treatment with overhead magnets and non-ferrous metals recovery through triple eddy current magnet systems. Additionally, organics and plastics are mostly recovered creating a mineral granulate fraction. 4. Washing and wet separation, creating a sludge (0-63 μm), a fine granulate fraction (63 μm-2 mm), a coarse granulate fraction (2-40 mm), and a floating organic fraction which is refed to the incineration process. 5. Finally, a last ferrous and non-ferrous metals extraction
