Chemical Precipitation of gold from poor man AR

Don't melt it between refinings, it's much easier to dissolve it in powder form.

If I remember right,Mr.Harold_V has stated that if you know your going to do a second refining of your powders,you should go ahead and melt them to help oxidize off more of the contaminants prior to the second refine to help improve purity.Maybe he will see this and correct me if I'm wrong.

... and the thread title it self did also contribute to my mistake. If I'm not wrong, HCl/Bleach is not poor man AR, a chlorine source with a nitrate salt is.
