One thing bro you had to denox?? How much nitric did you use?? If you start with few mills at a time on heat and with lid on reaction stops put few more mills in until it’s resolved and the more legs you remove before you start you will use less nitric because copper takes a lot of nitric and the more copper you need more liquid to dissolve the salts in but good job we’re is the water for SMB you drop gold you need double solution water???????

If you got 0.6g of gold from 1kg of IC chips why show the glass jar being weighed with 0.6g of unmelted gold in it at the end? Instead of additional gas, pump AIR into your fire to create a more intense burn FOR FREE. A covered kiln burns more efficiently than an open topped dish; Reduce inefficiency+costs to make recovery worth doing or you'll spend $35 on IC chips + $8 on gas/acid to get $24 of gold out of them.
