Using Geologic Maps

In order to see what geologic maps can do, we need to think about what we are looking for.

The Basics of Crushing and Milling Operations
February 2011
In processing gold, silver and other valuable ores, the minerals containing the values, such as metallic gold, silver-bearing sulfides or other minerals, must be freed from the surrounding host rock before those valuable minerals can be captured.

Iron Minerals, Your Detector and Gold
January 2013
It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.

Prospecting for Liberated Gold
November 2015
Some will doubt its value given the ultra-fine particle size… Some will become encouraged about not having to incur significant time and expense to break rock.

Gold Recovery with Centrifugal Bowls
July 2014
Centrifugal bowls are very efficient, and with proper operation they can consistently achieve gold recoveries above 95% with gold of about 50 mesh size.

Lode or Placer: What Difference Does It Make?
September 2014
This explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
