Greetings to all, I have a fairly good Idea of the process I have been working on for a good while to leach with AR, I have studied Holks book and some chemistry. Thanks to all of you. Thank you. I respect all of you who are knowledgeable and help us all. I believe I have enough equipment and supplies to work with now. (funny) I bought a digital microscope to be more selective of ore I am going to crush, and mill down to 80um and spend chemicals on to process. HA! I am a backyard miner in central Co. and have several kinds of ore I am trying to pick out the best, but I have decided I don't know how to use this thing yet. I wanted to put a couple pics on here to see if anyone could maybe help me at all with what resolution or magnification that makes it best to identify raw ores or 80-100 um particles. No pickers or much free gold in this stuff. Well AU is what I am looking for. It is 1080P has 3 lens 18-720X, 1650-2040X, and 2760-4080X and 3X digital zoom. If anyone can help I appreciate it. I don't have a very good turn around on assay's 6-8 weeks, but a friend has a mine up here that helps me out with their lab and equip sometimes, I haven't found much worth while yet, but I am not going to die trying. anyhow I am trying to use this thing to pick out AU and I know there is pyrite, Iron, copper, not 100% if the chalcopyrite is encapsulating AU or if it's all a waste. This is mostly double refractory stuff I have, sulfide ores I guess. Up here is several telluride ores, calaverite and sylvanite mostly, there is fluorite in a lot of the rock but not seeing a large concentration of what I am looking for in it. Still and I know I have to roast at 600 C. and I have that covered too, someone told me to add a little silicon sand in the beginning cool and add some charcoal after to take cyanide out??? I will also put a pic of a couple of the raw ores, one I think is iron sulphide, and another that shows fluorite and what I think is pyrite. Help. This other rock I thought was fluorite, but now looks like maybe sodalite, but after I finally split it I am not sure. Its a 6-7 hard it weighs 48 oz. it shows a lot of microscopic metals in it, and it does not glow under UV light. Help, Sodalite is not supposed to have metals in it not even pyrite. Thanks to all, I know I ask a lot, I really am just a humble little student.
