Small Mining Operations
Small-Scale Hard Rock Production
December 2015 by Staff
So far this year we have recovered over three pounds of gold and the hard rock veins seem to go on forever. We now have three claims that can produce good enough gold to set up a productive operation.

Uphill Battle Continues for California Dredgers
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.
Refractory Gold Processing
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
The Miner’s Switchback
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
Customizing Your Dredge
I am going to suggest dozens of ways you can increase suction power, dredge to greater depths, and improve recovery methods in your sluice box.
Pumping Water With Solar Power
Solar energy can be used for any size placer or hard rock mining operation. It is most practical for small and longer-term operations provided your mine is not located in a dense forest.
River Dredging vs. Creek Dredging—Part II
While river dredging in fast water, don’t be afraid of being swept out of your dredge hole by the current. If this happens—and it most certainly will in fast water—there is no need to panic. Don’t try to swim against the current because you will waste much energy in an effort to conquer the river. Just let it take you downstream.
