[QUOTE="XLOOX, post: 583003, member: 16174"] I hate to be a negative Nelly but some comments. A gold processing plant, even a small one, is best designed around the size & grade of the orebody & the type of rock & gold occurence. If you want to just use up stuff you have at home then what you make is unlikely to suit any particular persons needs very well. It may well "work" but the difference between getting 50% & 80% recovery on 5g/t head is $120/t and your 10hp plant should do about 0.5tph so the diff is $60/hr = $14500 per month. For that sort of potential loss I personally would want a plant designed for my specific ore. Thick wall pipe, even Sched 40 or even Sched 80 is still only mild steel, it will wear out relatively quickly - all rock mills have hardened steel liners to resist wear. Not sure what you mean by a shaker ? Sweco vibro mill ? Hard to beat a ball mill for reliability & simplicity... Aqua regia is VERY dangerous & will dissolve a lot of stuff in the ore besides the gold, you will need another liquor treatment method afterwards before smelting. I would do almost anything to avoid using this stuff in industrial quantities. Have you used aqua regia before? Cyanide is MUCH safer than aqua regia & running the preg thru carbon & just burning the carbon is a simple way of recovering the gold. Happy to take flak at this point but just wanted to save you some heartache & $$ [/QUOTE]
