Best practice of filtering copper anodes slimes

[Ayham Hafez]

If it goes through the filter, I'm not sure a filter press will fix much.
Maybe centrifugal concentration will be the best solution.

It's easy to test by making a whirlpool in a beaker by stirring, will check next week

There will probably be too much turbulence created by the swirling liquid.
Do you have a lab centrifuge?

No but I will use magnetic stirrer with 1400 RPM, isn't enough?

Should be enough, but a magnetic stirrer is designed to mix and do so by creating a high turbulence inside the medium.
A centrifuge for separating works by creating a high amount of "gravity" in a mostly stagnant liquid.

I missed this point, let's wait to see if someone here has experience with mud in centrifugal machine.

As I suggested try wicking the solution it’s good for solutions that are hard or impossible to filter.

Could you please describe how to wick the solution, this is first time I hear this term.

You put a piece of finely weaved fabric or rope into the vessel and let the capillary effect draw out the liquid.
One end of the wick needs to be in the liquid and the other end should be lower than the surface of the liquid.
Often a fine filter or cloth can be used to separate the wick from the liquid as an extra precaution.

Do you mean the other end higher than the surface of the liquid.

Usually I use cotton wick in a funnel to filter dirty acids, I make it long and make sure the liquid surface is under the end of the cotton wick.

If its the same of my cotton wick idea then it will not work cause I tested it many times, it will work until all pores closed and usually they are closed quickly even if the top end of the cotton wick is clean and upper the liquid surface. Please inform me if it's not the same idea

Or you mean like this?

Yes, like what is shown in the video.

Thanks, it looks work well, will put large piece of woven fabric in plastic noodle strainer, make sure the end parts of it lower than the bottom of the noodle strainer.
