How Rich Must My Ore Be?
May 2021 by Chris Ralph
How rich does a hard rock ore have to be for it to be worthwhile to process and extract the gold?
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
If the material drops down out of the hopper too fast, it can overwhelm the riffles and you can blow the gold right out. If it runs too slowly, the riffles can clog up and the process is too slow.
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
Even if you are not ready to cash in right now, it might be good to evaluate your options and make a plan of action so when that day comes you know exactly what to do.
Feeling through the mud, I felt the weight and shape of what could only be gold. Throwing my hand in the water revealed a sixteen-gram nugget oozing with character.
This type of thinking will get you discouraged pretty fast, and soon all of your mining equipment will be found gathering dust in your garage.
