February 2012 -- econ industries and SAKAB are currently developing a new process for the recovery of calcium fluoride from filter cakes accrued during stainless steel processing. To recover the valuable calcium fluoride, the filter cake needs to be dried, which is difficult due to the properties of the filter cake. Laboratory tests carried out in 2012 demonstrate that the VacuDry® technology is the ideal choice for this challenging application. The first plant of this type is currently in the design phase, with the commissioning scheduled for 2014.
