Refractory Gold Processing
February 2013 by Thom Seal, PhD, PEAfter 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.
Selecting the wrong coil can potentially cause you to miss nuggets, so you want to be sure to select the best option for the situation at hand.
The burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
Even with my favorite top-of-the-line gold detector there were several false digs. Many of the hot rocks gave a solid signal that was too much like a nugget to ignore. After trying several tests I just dug everything because it is better to be safe than leave a big, deep nugget for a more diligent gold hunter.
How big is the deposit? Are there boulders you will need to move? Do you just want to recover the nuggets or do you think there is good fine gold that you will also want to capture?
...we finally got back to this exploration effort. The old works there were up above the old camp, which was very significant in size.
Much more information can be gained from that single source and gives you ideas on the gravels for dry washing or where the nuggets may lie for metal detecting
I didn’t know what to expect because the area we were working was not close to the water, but we were pleasantly surprised when we began to pan out some nice flakes and a few pickers.
