Small Mining Operations
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.
Since we’ve already covered the basics of permitting a “Notice Level” mining operation, it’s time to talk actual mining.
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...
Fortunately, there are products on the market that can address these problems and make a small-scale mining operation feasible.
They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.
I’ve been following the precious metals for decades, and I haven’t seen a move this powerful in many years.
Let’s set up a thought experiment: Suppose you had some material that ran one ounce per ton gold, which is generally considered high grade to fantastic grade depending on the circumstances.
I’ve been in enough mines to know better, and I mentally kicked myself several times. That was a close call…
They worked their plan, bit by bit, and sure enough, after the blast, gold was detected… Over two pounds of beautiful crystalline gold was recovered in that stretch!
…let’s dive in and take a closer look at these rich gold and silver-bearing minerals to find out what they are, where they form, and how to identify them.
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
…as an academic argument, when mated to the appropriate engine, is the pump really moving water at the rate of 400 GPM?
Micro blasting can be used to take down hanging rock, separate minerals from overburden, and collect gemstones and other high-value product with minimal damage.
The problem is that extracting gold from hard rock is often a lot more difficult than processing placer gravels. Still, there is some very high-grade ore out there in many old mining areas.
