Hi everyone. I've been lurking and learning here on gold refining forum for about a year now. I've been prospecting and developing a few gold deposits and I am at a point where I have a good source of quartz based material with visible gold and some locked in sulfides. The gold is very fine. I haven't had success with physical recovery methods. Some success on a small scale with amalgamation. I've investigated chlorination, and cyanidation thoroughly. Done some experimentation with chlorine. Experienced some trouble keeping the ORP (>1000) and Ph(>7.5) in the right ranges. Chlorine is really nasty stuff. Caught a couple strong wiffs once or twice and called it quits. Not really willing to deal with cyanide. I am curious on people thoughts about thiourea. I know it exists but not much about the practical side of the process. Are there other processes that can be practically executed by the layperson with the necessary research, understanding, experimentation and access to resources? Are there people in the western united states who will smelt/ leach/ purify/ work with raw ores? Average grade by fire assay is about 1oz/ ton more or less depending on wall rock/ gangue dilution.
I crush the material to 1/8" minus then grind to powder (around 40 mesh). Could grind finer. Finding the gold is only half the work. Getting it to a marketable form takes respectable effort. So far been the funnest hobby I've ever had. Would like to see some gold for the effort. Thanks for sharing your knowledge and experience.
