intensification and stabilization of vacuum filters for dewatering of iron ore concentrates (IOC) can be effective when using chemicals - surfactants for surface modification of particles filtered in such a way that on a pile-up step a thick cake is formed, and at the drying stage -water is removed effectively from its pores.
The technology of filtering iron ore concentrates slurry with the use of a nonionic type surfactants CLEARON S 900, developed by specialists of EWB s.r.o., can substantially improve the efficiency of disk vacuum filters.
