Using Countercurrent Material Flow to Improve Gold Recovery Efficiency
December 2020 by Keith Bowen
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...
It was round and I thought it was a dirty piece of lead shot, but after feeling the weight and giving it a spit-cleaning I knew I had one! Small as the nugget was, I felt happy and gratified for my little success
The same questions you ask yourself about gold trapping features in the present stream can be applied to the benches above the stream. Just imagine the stream at a much earlier time, before it cut its way down to the present level…
As I write this, I am still on a rush from taking my 9-year-old son, Jeffrey, prospecting for the first time this past weekend. It’s not that he hasn’t been along on numerous outings before: this is the first time that just the two of us went out for a day of drywashing and detecting under the desert sun.
Within this area, about two million ounces of gold and fifty million ounces of silver have been mined. Faults, dikes, veins and fissures that carry the ore form a concentric radial pattern—like spokes on a wagon wheel—around the caldera core.
Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.
Prospectors have many reasons why they might want to break rocks. These include dividing up a specimen too large to carry.
In our May 2013 issue, we took a look at the mineral quartz, a mineral very commonly associated with gold. However, gold is not the only reason prospectors are interested in quartz. Quartz can also be very valuable as a gemstone
