It may take hours gallon or two of solution or days 100s of gallons but you will end up with a crusty piece of metal that can then be melted and assayed This only makes sense if there is a sufficient amount of gold in the bath When you consider the time and electricity used it doesn t make sense for half a gram of gold

help on recovery of microscopic gold from ore Aug 02 2024 0183 32 need help on recovery of gold ore i found 3 years ago its a grounded ore I USE AQUA REGIA on it and i precipate gold with smb i always get a orange brown powder light brown color ido a lot of cleaning with ammonia and Iuse AR on it again precipate with smb get same powder but the probleme I cant melt it even at or over 1200c

Aug 1 2024 #3 rickbb said Most ore requires a good assay to determine exactly how to recover any gold Using AR on ore without knowing what the assay says is a very bad thing to try Also AR on ores usually do not produce the results you want as you have learned Most likely you have other metals in the ore some that may even be toxic
