Hard Rock Milling: A Matter of Scale
April 2013 by Chris RalphMost prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
“I heard him hollering down in the hole as soon as I got there,” he said. “I was just glad to see him alive.”
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.
I grew up in Southern California, and found my first nugget there, so I know my way around. Because there is good gold there, I thought it might be helpful to take a look at the many placer gold opportunities found in the southern part of the state.
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
A very good baseball hitter might get a hit roughly one time out of every three at-bats, but for prospectors often the results are much sparser and it may take many trips before the prospector hits a home run.
It was round and I thought it was a dirty piece of lead shot, but after feeling the weight and giving it a spit-cleaning I knew I had one! Small as the nugget was, I felt happy and gratified for my little success
The design of metal detectors well-suited for prospecting is an interesting process and not necessarily an easy one to achieve. It is a combination that blends the desires of what prospectors would like, the requirements of sales people and dealers, with the science and physics of what the electronics can achieve.
