After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
Centrifugal bowls are very efficient, and with proper operation they can consistently achieve gold recoveries above 95% with gold of about 50 mesh size.
