Small Mining Operations
Preserving the True History of the Ivanhoe
April 2019 by R. V. Larson
My partner had the contacts and it wasn’t long before we had an agreement in place and the company had a geologist on site. I recall a time when he was getting the lay of the land, so to speak, and he broke off a rock sample and inspected it with his magnifier.
Lode or Placer: What Difference Does It Make?
This explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
How to Make a Rock Sled for Dredging
When my “anonymous” friend told me the rock tub was probably a hundred miles from where he safely stashed it, I decided to build another sled and improve on my old design.
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.
One of the Richest Beaches Ever Mined
Everyone has heard of the golden beach at Nome, but Nome did not have the richest beach.
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 Fire Assay of Carbon
Carbon, activated charcoal, or “char,” as some old timers refer to it, can be an assayer’s nightmare.
Gold in Tertiary Gravels
In some places, semi-continuous sections of riverbed can easily be linked in many places to identify the path of the ancient rivers.
