What was your feedstock?

I used black powder from sulphric cell plated pins

If you followed lazersteve's cell black powder process to the letter, you have 2 options:
1. try adding water - if the HCl-Cl is too concentrated, sodium salts can precipitate out. If they dissolve - EZ fix.
2. If they still don't dissolve, you probably have carried some lead over from the cell - its impossible not to. Just filter the solution before precipitating.

If you didn't follow the procedure, you could have other base metals. But I wouldn't worry. Dilute the solution with 3-4 parts ice water, or just ice, & filter anything that is still undissolved.

If super purity is your goal, you can dissolve the powder again & re-precipitate.

Make sure you post some photos of your end product.

good luck!
