Traveller11,
I do understand, I have been working placer gold for years, I have also worked sand beds, it has always been a hobby for me, I make and use some mining equipment, nothing on a large scale, shaker tables, blue bowls, spiral wheels, classifiers, and dredges, and various other equipment, if your working large volumes of sand, and do not wish to pan, there is equipment you can make or buy, most all of this equipment comes down to the point i have been trying to get across to you, but in my view you are wanting some magic leach that works to remove gold without pretreatments like concentrating roasting and so on, there are some leaches that are specific to gold, but even these you would need to treat the ore, when gravity is your friend here, yes you can try to leach, but if the gold is free from the ore, I would use gravity to get the gold concentrated, if not totally separated from the sand and other materials, once concentrated very well smelting would be an option, leaching would be my last option and only then from a very concentrated gold material, with pretreatment, the leach first would focus on base metals, and then the values.
Mining supply houses have the equipment you need, I personally would not go out and buy equipment before I got gold, I get the gold then I add to my tools, for instance I would not go out and buy some big new dredge, I first would work my pan, (in fact many of my first pans were not store bought, I learned to pan gold using a hub cap from a truck, and even today I sometimes use a hub cap to pan gold, I would get some gold then take that money and build me a sluice box use that to get more gold then work up to building my dredge built from scrap metal, an old lawn mower and a scrap pump, later I upgraded the dredges I built, I have several now and still have no need to go buy a new dredge, Yes I would love to have one of those big Keene dredges, and a air compressor, but unless It would pay for itself better than my homemade tools do, I will just keep the gold I have now, and not trade it for a shiny new dredge, that may not pay for itself.
I have my ideas, of how to recover gold, you have yours, I have tried to share my ideas with you, you do not seem to like the way I see this, you seem want to hear what you want to hear. I will not change my views just to say what you wish to hear.
I could most likely work the sand you have with screens, a drain pipes, and a pan, and a few hand tools, if the gold was there I could, scale up the equipment, either made or bought from the gold recovered.
You can run a lot of sand through long toms, and with miners moss and good riffles, and side boxes you can collect almost all of the gold that went into it.
If you set up the equipment right you could capture more fine gold than the old miners did when they used mercury coated copper plate’s, and some of the modern separators can separate the sand from the gold (no matter what size better than some of the best hand gold panner’s).
Gravel companies in my area, sell tons of the black sand they ship it to china, this black sand has the majority of the gold removed, but still contains considerable values, if you are working large beaches, with good values maybe you can mine them in a similar fashion, with large equipment, selling the lighter sand for cement, collecting some gold and ship tons of black sand to china, personally I hate to see our valuable raw materials go to china.
I see many miners in my area go out and buy High dollar equipment, you they do move more material and do get some gold, but it has not paid for their equipment, so in my mind they are gold in the whole, spending more gold than they have mined, I do not get as much gold, but my gold is all profit, my equipment is paid for, and now I can buy larger equipment if I wished.
If your stuck on the idea of leaching, I have never tried these but action mining sell some leaches, you could try them (they may or may not be something like sodium thiosulfate), I am not sure of the name but it seems to be CL6 or something like that, give the girl who works there a call she can help you better than I seem to be able to, she may have the equipment or the leach you need at a price you are willing to pay.
