Shaker Tables for Processing Hard Rock Ores
May 2017 by Chris Ralph
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.
I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
There are currently three controlling agencies or entities over suction dredging in California—and you can make that four if the state legislature decides to further muddy the waters with additional legislation to block suction gold dredging in the state.
Everyone has a bucket list, and one of my items has always been to dredge and dive in a major river, Oregon’s Rogue, with the opportunity to find some chunky gold.
With eight loads processed, a pumpkin-size rock fell into the hopper, stopping the whole operation until I could lift it out.
It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.
Q: How do I improve my small-scale mining operation’s gold production?
I knew the nuggets got into the nugget patch somehow, I just had to figure out how and from what direction they came.
