Recovering Gold From Worn Out Mill Liners (2 replies)
Please join and login to participate and leave a comment.
In our grinding circuit, we have a SAG mill that uses rubber liners. Once the liners are worn out and replaced we sell the old liners to a company for a credit where I am guessing they either burn them or leach them in a tank to recover the gold embedded in the liners. They are shipped to South Africa to be processed so guessing there must be a pretty good amount of gold inside. We are not sure how much gold is in the liners and have always just sold them for a credit. Wondering if anyone has tried recovering the gold from their old mill liners on site and what the most effective way to do it would be and if it was economical to do so. Thanks
