Vacuum Filter

Filter paper pulp vacuum filters better than you might imagine. It no longer has a structure that clogs.

Wicking works.

Gill,

Thanks for posting the photo. It's great to see the wicking filter used with different setups. It really does work, especially for hard to filter sludges. Recently, I used it for x-ray film emulsion, which quickly clogs in normal filtration, and it worked great. The wick can be slow, but it never clogs or stops.

The wick is actually fairly quick if your not standing there in anticipation, the wick in the picture siphoned out 5 gallons in two days, I've already added a fresh rise to the pulp.

The beauty is that wicking leaves fine slimes behind. I also learned that of you leave cemented PGM blacks for a month you need a chisel to break it loose from the bottom of the pail.

I do have a question though, the pulp I'm working with is milled cat combs leached with AR for over a year. From what I gather home recovery is not 100 percent there's going to be some platinum group salts left behind.

What if I added some iron to cement any values left behind in the pulp then incinerate, I'm thinking that I should add the incinerated pulp to the virgin pulp I have milled that I plan to ship out for refining.

I've also thought an assay of the spent pulp would be a good idea, this could save me from unnecessarily contaminating the virgin pulp. Thoughts anyone.
