While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
Most placer equipment is really made with gold in the 30 and larger mesh sizes in mind, though if carefully used can often get reasonable recovery down to the 50 mesh size.
Many specimens have a small amount of gold and are not pretty to look at. There is a nifty way to give them a makeover and make them much prettier than they were when you found them.
I’ve had great success using it to gather gold from crevices. I’d like to share the design with all of you gold miners reading this article and hope that you get as much satisfaction building and using it as I did.
Choosing the right method to move your ore and waste is all about making the right choices. Sometimes more than one method may be used during the life of a mine as an operation expands and grows.
Q: I am looking for a “trommel machine” that doesn’t separate anything but clay slurry from rock hard clay.
These three simple upgrades, when taken together, will considerably increase a pocket plunger’s magnetic pull and make it less susceptible to breakage.
Q: Can and should you remove their poles and notice right then and there or should you wait until you have convinced them of their trespass?
The anticipation of finding out if the system of snatch blocks, shackles, chokers, anchor points, and the strap binding the massive slab of rock in the bottom of the river would even budge an inch was weighing on me.
Ditches almost always started in the high country and contoured the mountainsides, making a long drop, usually many miles away, to the goldfields. There are ditches in Trinity County that originate at seven and eight thousand feet in the Trinity Alps that carried water almost thirty miles.
Q: With safety as a given, what can the average miner, or Joe-blow greenhorn do to identify and extract some metals or minerals with off-the-shelf products or natural ingredients?
Which comes first, claim filing or staking?
When doing your initial armchair research and selecting potential areas to explore, consider all the indicators, both natural and man-made.
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.
