You adding to much aluminum in the beginning . You need just that much aluminum hou much gold can be in solution . Adding a lot aluminum makes big mess and you don’t get more gold anyway . If there is 1 gram of gold then you need add 2 grams aluminum maximum !!!!!!!! And wach solution if there is gold solution change color from yellow to brown . If color is green there no gold in solution
