• Pozzolanic activation and characterisation of the activated clay raw materials with regard to their usability as geopolymers Project (Mineralogy & Geochemistry)

  With the planned coal phase-out in Germany by 2030, fly ash, a widely used supplementary cementitious material (SCM), will no longer be available. will no longer be available. Among the potential alternatives, activated clays have emerged… (Pozzolanic activation and characterisation of the activated clay raw materials with regard to their usability as geopolymers

  

• Recovery of lithium from the recycling slag of lithium-ion batteries Project (Mineralogy & Geochemistry)

  By using proven pyrometallurgical processes, many valuable metals can be recovered from lithium-ion batteries (LIB) (e.g. Ni, Cu, Co) as alloys or metal sulphide. However, lithium dissolves in the slag, from which it cannot currently be… (Recovery of lithium from the recycling slag of lithium-ion batteries

• By-products from lithium processing from spodumene Project (Mineralogy & Geochemistry)

  The extraction of lithium from spodumene produces leached spodumene concentrate (LSC) as a mineral by-product. Previous studies have demonstrated its promising pozzolanic potential and suggested its suitability as a cementitious material… (By-products from lithium processing from spodumene
