Small Mining Operations
Since last year’s articles on explosives for mining, several people have asked for more information about becoming a licensed blaster.
How rich does a hard rock ore have to be for it to be worthwhile to process and extract the gold?
Imagine you have located a source of virgin placer ore containing immense gold value. Now imagine that there is a 10-ton monolith of extremely hard gneiss in between you and payday.
…there is an easy way to create a reasonably accurate map without any fancy instruments.
…to see the huge differences between the gold production amounts of the Western States, let’s look at the gold production—both hard rock and placer—of these 13 states up to the present.
Whether you are placer or hard rock gold mining, maximizing the efficiency of your recovery process is very important to success, and accurate testing is necessary to do so.
Prospectors often wonder why gold deposits in veins like it does. Why is one vein rich while another is barren, even though they are only a few hundred feet apart?
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.
There are times when being able to recognize a type of rock can make you a much more successful prospector.
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.
With the recent surge of interest in gold projects, it’s about time to revisit a subject that strikes fear into the hearts of small-scale miners: Permits.
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...
The small-scale miner has reasonable opportunity to exploit some of these small, rich placer gold deposits.
They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.
