The new paper titled "Nepheline Syenite as an Alternative Source for #Aluminum Production" by Maria Bagani, Efthymios Balomenos, and D.Panias is already available online
 
The increasing demand for aluminum in conjunction with the limited available bauxite deposits in Europe results in the dire need for the evaluation of alternative raw materials for the
whole value chain of alumina production. This work presents a viable approach for holistic utilization of a mine waste product –nepheline syenite– as an alternative alumina source as part of the AlSiCal innovation programme. The results show that the aluminum-bearing phases that withstand the dissolution process are mainly the ones of sodium and potassium feldspars.
