How do you precipitate gold from cycnide plating solution? (No replies)

Hello, I'm new to this forum so thanks in advance for any help. We regularly send out gold solution for reclaim but I would like to find a better way of knowing what to expect from this solution and obviously AA isn't the best option for this. Everyone I talk to says precipitation and fire assay is the industry standard for this. I've been looking at using sodium metabisulfite for the precipitation but I'm having trouble finding good information on how I should destroy the cyanide before moving forward with the precipitation. We deal with cyanide destruction here in our WWT system but I assume chlorine isn't going to work for this. How does others do this? Any advice would be great. Thanks again!
