What is the best method for extracting gold from quartz
11/10/2018#0183;#32;What is the best method for extracting gold from quartz? The commercial way is with cyanide, but when assaying I would pulverise the quartz, place it in a retort with a 4 iron nail amp; a cup of oatmeal {other flours are acceptable assaying does not need to be glutenfree}. Place in a blast furnace, melt down, remove amp; allow to cool.
