Small Mining Operations
The Jenkins Mine Project, Conclusion—Recovery Operations & Summary
November 2010 by David Shackleton
This project taught me that you don’t need to be Albert Einstein to apply a little science to your prospecting. I learned that most of the science related to suction dredging is actually common sense. All we need to do is take the time to apply it.
Dredging Tips and Tricks: A Measure of Water Pump Efficiency
…as an academic argument, when mated to the appropriate engine, is the pump really moving water at the rate of 400 GPM?
Speed Prospecting for Hard Rock Gold
An online video gave me some ideas, and with a lot of trial and error I developed a reliable method of panning free gold particles down below 35 microns quickly and easily.
Hard Rock Milling: A Matter of Scale
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
Principles of Designing Your Mill Production System, Part II: Mill Design
Starting small with quick profitability gives you a lot of financial elbow room plus real-world experience that can be used for final mill design.
Finding Gold in Tailing Piles
Old mine workings and tailing piles can represent opportunities on many levels, from the chance to simply find a nugget on up to the commercial reworking of the old tailings for profit.
A Test Grid Dredged for Gold Values
The evaluation must also consider the gold fineness or purity. The purity of the Sugardaddy nuggets is estimated at 850 fineness, meaning 85% is gold (Au), 12% is silver (Ag) with 3% being other gangue alloyed metal.
The Basics of Crushing and Milling Operations
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.
