Enrichment of Mineral Deposits by Weathering—Part I
March 2016 by Chris RalphThe exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.
The University of Nevada, Reno Mackay School of Earth Sciences and Engineering, Department of Mining Engineering has begun offering online courses for miners.
Exposed veins and outcroppings can be a great source for gathering good gold ore for processing. Veins and outcroppings do require a lot of work to free the ore from its earthen grip, but this labor can be very rewarding.
Science has shown, over the past few centuries, that there is a direct correlation between certain plants and their geophysical surroundings.
Getting started in prospecting often requires the purchase of some equipment, but one can spend as little as $10 and be finding gold or spend thousands and also be finding gold—yet you will probably have many more opportunities and possibilities with more and better equipment.
…the process remains much the same: Drill holes, load explosives, close up the holes, blast and muck out the resulting broken rock.
I researched the Internet and found a number of table makers, but technology has changed in the last 25 years. No one could sell me a kit for a new deck with wooden riffles...
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
