sport.pilot Posted June 1, 2009 Report Share Posted June 1, 2009 Hello all,We have a hardrock mine in Mojave County that is producing fine gold. We Crush the ore in a rod mill, then in an impact mill, and and then use a concentrating table to seperate the gold from the black sand/clay. The ore has been assayed several times at .82 to 1.2 onces to the ton, averaging a little over an ounce to the ton. So, it has been worth the 4 years of effort to figure out how to get the ore out and get the gold out of the ore the easiest way. It is to fine to use a blue bowl andor to pan, because a lfair amount of it is micron in size.So, now that we have the fine gold separated fairly well, we need to learn how to use an oven (which we have) to fire the gold and get it into a form other than fine powder. We want to be able to pour small bars. Does anyone know where we can learn how to do this? A video, a web page that explains in detail how to make a flux and a step by step process how to mix the flux with the seperated gold ore, fire it, and pour it into a cupel and ultimately melt all the small buttons so we can pour small bars? Or an expert that we could pay to show us how do to this all? Thanks.Darryl Quote Link to comment Share on other sites More sharing options...

The small Centrifuges are THE most expensive. Far more expensive than these: ---Blue Bowls(~$75) http://www.pioneermining.com---LeTrap and Angus MacKirk plastic sluices---S-1 Finishing System($195) http://www.usprospector.com/index.php/finishing-machine---S-1 with Vibratory Feeder($349) http://www.usprospector.com/index.php/buynow---All the Micro or Mini-Sluices(~$300-$500) http://www.micro-sluice.com and Midas(318)-464-9354---All the Gold Spiral Wheels(~$300-$600) Camel--Gold Miner--Gold Screw--Gold Magic---The new Keene Super Concentrator($395) http://www.keeneeng.com/---Mountain Goat Trommel($695) http://www.desfox.com/M.G.TROMMEL.htm"They are in Salome, about an hour west of Congress. We use RP4's for concentrates. I've been there a number of times. They(RP4) work great. I swear by them."What others have said on the Alaska Gold Forum about the RP-4. Seems like all good reports:New Keene Super Concentrator?http://bb.bbboy.net/alaskagoldforum-viewth...2&thread=41"So after researching finishing tables it looks like the RP-4 is the best shaker table that would take you ALL the way there.""Yep that's the one. It was originally sold by U-Tech and I guess the company with the website you listed (which is shown in the California Mining Journal ads) sells it now. I read a post from a guy in Alaska that has several different shaker tables (including the gemini) and he preferred the RP-4." "Got that right, RP-4 worth every penny or it's weight in gold!"Hope this helps, if anyone can add more to this, go ahead. Quote Link to comment Share on other sites More sharing options...
