Solar cell recycling; production of ferrosilicon

FesiLeg utilises two waste streams, red mud and waste silicon (mainly of-cycle solar panels or dried saw slurry), to recover a new valuable and competitive resource, ferrosilicon. This technology offers the possibility to add other metal oxides as chromium, nickel, titanium, vanadium and others, in order to obtain ferrosilicon alloys with these metals. By this, the ferrosilicon alloys are produced with much lower energy consumption and without primary material usage – and they are free of carbon!
