It might be wise to adjust the pH a bit before step 2 first.Precipitate from AR1 and AR2.. will give AR2 another 24 hours as it is behind in processing by a good day of sunshine. Next step, I will pull off as much solution as I can.
Question: 1st step in waste processing I think i read as adding copper. Will pre-82 copper pennies work ? 95% copper/5% zinc ??......
2nd step - add iron
Final step pour solution in fire pit ash and burn another layer of ash onto it while I roast the next batch of REDNECK ore in same fire ?
But the best for step one will be pure Copper bar or similar.
The Zinc will precipitate most all other metals as well, in this step you are basically just double checking that nothing of value has passed you by.
The Iron cementing will drop almost pure Copper.
