Recharged Particles is working on a patentable process to recycle waste FeCl2 from sheet steel manufacturing and TiO2 pigment manufacturing that will recover 98+% of your HCl and generate a new nano-magnetic raw material.
Unlike spray roasting this process is more energy efficient and generates no dust or other environmental disposal problems.
The nano-magnetic by-product will revolutionize the magnetics market with lower costs to produce more powerful magnets.
