Complex recovery of mineral mining and industrial waste as secondary raw material in the context of eco-conscious building materials andhydrometallurgy

Pressure for new waste-free and CO2-neutral technologies remain high and, in the context of commodity security, the landfills of the pastmust become the deposits of the future. The objective of the proposed project is the complex valorisation of mineral waste streams, which will be carried out through thedevelopment of waste-based building materials and critical raw material resources, as well as the reduction of the carbon footprint basedon carbonization technologies. The expected results are basic and applied knowledge (a) the valorisation of local mineral industrial waste as a lightweight building materialbased on the necessary technical characteristics such as strength and thermal insulation, sound attenuation, durability and environmentalperformance, and CO2 sequestration; (b) integration of extraction optimized for raw materials with a low Mg content (4-6% MgO) in the keyof critical raw material resources into a potentially waste-free ash hill valorisation complex.
