Hi folks,
I am preparing to do my first refine of foils I have collected from escrap. I have 3 modest batches in storage jars in water. One is relatively clean, from cleanish boards and fingers. The other two smaller batches are from sources containing solder and other base metal contaminants. I intend to dissolve them with the bleach method, drop the lead out with sulphuric, filter and drop with copperas. Before I dissolve them each jar separately will be roasted and then soaked in HCl to clean up residual oxides.
My question is, what are peoples opinions about combining the foils before dissolving, so that I only have to do one drop, or should I dissolve them separately and do 3 separate drops?
