Respected Members
I collected copper ores from different mines. Grinded them with a handheld hammer while putting that powder in a glass beaker and poured some nitric acid in it. then added some salt. Kept it for 10 minutes while stirring it with a rod. After that, I poured HCL into the solution. Again, I kept it for 10 minutes and then filtered the solution into another beaker. I then dissolved some ammonia into water and added that water to the previous solution. After a while, I added urea and after that, I dissolved iron sulfate into the water and added that water into the original solution. Kept the solution for 24 hours and the gold dust was dropped in the bottom of the backer. I collected that dust and washed it with water and HCL again. The dust looked like golden mud, a picture is attached which is taken from the net but the mud I obtained was very similar to the attached picture. I then put the mud into a crucible, heated it with a gas flame. The mud turned like red coal and after I released the heating process, it converted into black carbon, not gold. My questions here are: Whether I did the process correctly/ Whether the mud I obtained was gold/ Whether I did something wrong during the melting process? Or any other method, recommendation from members? I would highly appreciate all your valuable comments.
Kind regards
