explorer1 Posted June 21, 2020 Share Posted June 21, 2020 Hey all, I recently smelted and refined my gold into a gold bar. I used my newer electric furnace set at 2000 degrees Fahrenheit. I let it smelt for about 30 minutes in a graphite crucible. Using equal amount of borax to gold ratio with adding a small amount of soda ash. Twice I refined and came up with a scratch test of about 16K gold after breaking off the slag and cleaning the bar into a nice shine through many different cleaning processes. Is there anything else can you suggest I add or refine differently to gain more purity. I do not want to go into various types of liquids. Just smelting and refining. I would appreciate any help. Thanks beforehand.--Jim Quote Link to comment Share on other sites More sharing options...
Morlock Posted June 21, 2020 Share Posted June 21, 2020 I'm no expert on this but from what I know, I don't believe so. You'd have to use aqua regia to dissolve the bar then precipitate the gold out using a reagent. That's what I've always done but perhaps the methods have changed since then. 3 Quote Link to comment Share on other sites More sharing options...
clay Posted June 21, 2020 Share Posted June 21, 2020 (edited) What ore are you smelting? Edited June 21, 2020 by clay Quote Link to comment Share on other sites More sharing options...

No ore, just gold from Idaho, Alaska, Arizona, California, and some from Australia. Gold smelted into a 9.93 OZT bar. Quote Link to comment Share on other sites More sharing options...
clay Posted June 21, 2020 Share Posted June 21, 2020 Ah ... I misunderstood. Smelting is the process of heating ore to extract the free metals contained in those ores. I think you are not so much smelting as melting your gold. Is your intent to remove the other metals from your gold to make a 24K (pure) gold bar?

Indeed, I'm trying to get more purity or as close to 24K as possible. Quote Link to comment Share on other sites More sharing options...
