Hello All,

I have a solution of material from an ore source which was digested in an environment similar to Leoretilus AR as mention in this thread

"So I left a couple of these buckets uncovered in the warm southern Californian summer sun and as the water evaporated away I saw a rainbow- like skim/skin form on the surface of the buckets, first it looked like a clear slime, later as it got thicker it displayed the irredescent effect reminescent now from what I know of the Peacocks tail, and still after a few more days as the layer got thicker, it turned into a metallic layer of the finest gold. I melted this into more gold in my furnace and drove it to the refiner and it came back as 99.5% fine gold for which I was paid nicely."

My question is what exactly is happening here? Is it a case where you MUST use sunlight or he could have just further process the acids by evaporating the fluid down to dryness?

What if there was no sunlight then what alternatives do you think would have worked?
