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.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
I metal detected a number of years before I saw my first nugget peeking out from the dirt before I had scraped or dug for it. This one was in the steep sidewall of a narrow, but deep drywash.
Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
I will make the assumption that when any of you take a detector in your hand and head out prospecting for gold you are probably anticipating finding some gold. That’s the general idea, right?
Some of the gold is placer that was beat up as it traveled; however, quite a bit of the gold is pocket gold that is running along the surface in this area.
