Because zinc slag iron in silver symbiosis, can use iron has characteristic of high permeability, using the method of magnetic separation for recycling iron silver symbiotic granule. After grinding of minerals into wet magnetic separator can be iron silver particles separated from waste residue symbiosis, achieve the goal of recycling iron silver symbiotic granule.
Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.
