June 2016 by Chris RalphQ: How do I improve my small-scale mining operation’s gold production?
Over the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
Most small-scale miners want to know how they can set up a system much more cheaply. The difficulty is in the balance of putting together a decent small-scale system at a reasonable cost.
It all started with a phone call from my friend and prospecting partner Pat Keene. He told me that he knew of an investor who was just starting out in the gold industry and was looking for a gold consultant to go to Africa to prospect and analyze a 400 sq. mile concession in the middle of the Congo rainforest. I waited for the “just kidding” line...
The same day, while two of us were heading to Vancouver to attend the mining convention, two others from our team were headed to Nevada to begin loading the millsite equipment.
