Sam, Wash with water, then let settle until the color of the wash water is no longer blue. If you want to be extra clean test a few drops of the rinse water with a drop ammonium hydroxide (3% unscented household ammonia will do), a blue color indicates coper is still present and you should wash some more. After the water rinses hot HCl and water rinses are good.sam said:diluted yesterday (1:2.5 ratio)' i'm gonna wash with water 3x and then HCL 3x
would you recommend hot HCL wash?
See note above about 3% ammonium hydroxide, you should be able to get it in any grocery store. I personally don't wash with nitric any more at all.sam said:i don't have at the moment ammonium hydroxid or nitric acid to add to the washing phase...
Yes, cell powder may contain some silver.sam said:i understand i'm risking having silver in my powder?
Depends on your goal:If you want pure gold then dissolve, filter free of particulate, and precipitate with SMB.sam said:should the powder from the cell be dissolved (HCL+cl) or just wash and melt?
My money says its SO2, but I wonder if it's possible to create hydrogen sulfide by this process? Could prove deadly if you breath much if it is.samuel-a said:BTW, what are the fumes (and terrible smell) that is coming out whan addind the SMB ?
