February 2013 by StaffThe University of Nevada, Reno Mackay School of Earth Sciences and Engineering, Department of Mining Engineering has begun offering online courses for miners.
The technology used in these devices has advanced greatly in the last century. Many different types of physical effects are used to measure these magnetic fields and we will briefly look at some of these.
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
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.
