Principles of Designing Your Mill Production System, Part I: Starting Up
January 2021 by Keith Bowen
One of the issues that prospectors run into when working to upscale from micro-scale hard rock testing to a greater production output, is that they often confuse individual devices or machines with systems.
Whatever system you plan to use will require a way to safely initiate the explosives from a distance. In this article, we’re going to learn the basics of electric blasting and get a hands-on example…
They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.
If Epd is larger, then the compressor will be spinning faster than the manufacturer’s maximum specified RPM and might destroy itself. If this happens, then the compressor again might not produce enough air to support a diver. Neither is a desired outcome.
We’ve been busy with a plethora of projects, all aimed at gathering gold into a pile big enough to brag about. We’re not there yet, but I’ll show you some of the interesting projects we’ve completed since we talked last.
It was time to prime the pump and start the engine! Dan’s priming method is to use a small, submersible, 12-volt pump. My priming method is to use a hand-operated diaphragm pump.
The favorable geology of the northeastern and central parts of the Seven Troughs Range are the parts most interesting to prospectors. They are underlain by a thick sequence of Tertiary volcanic rocks, mostly rhyolites and andesites.
In an old mine that does not have stopes, you know the old miners did not take much if any ore out of that excavation. On the other hand, if you see large stopes within the mine you know that it is these places where the miners found profitable ore deposits within the vein.
