I have zinc dust with impurities of Iron in it. Can somebody suggest efficient techniques for removal of Iron from zinc dust; except magnetic separation.
First you find the two different solvent of composite material (in composite material any one can be disperse solvent) then you separate (Filter the solution)
Dear Rakesh,
I have zinc dust fine powder of 200 mesh. I do not want to make it wet as it would increase the Downstream processing. I would like to know if there is some technique which can enable Separation of Ferrous material while it remains Dry.
You may use magnetic separator, or simply revolving magnet with constantly increase the strength of magnetic field as per your appratus available.
Or you can use acetone, quickly disperse your material and filter it, acetone will evaporate from your zinc dust.

Dear, Elad Alfassi and Aabhas Upadhyaya,
Currently i am using Magnetic Separation Technology. The rate is 10 TPD. But the requirement has Increased now. And if I further increase the machine magnet speed then centrifugation occurs and separation efficiency is affected. Hence i am looking for alternates.
I am intrigued about the use of Acetone as solvent. Can you please clarify the process.
Dear All,
I am pleased to inform that the problem is solved. We changed the magnet diameter . By taking a larger magnet we can pick up speed. But the rpm of the machine is to be adjusted. Still, thanks for the valuable input.
