Ask The Experts - I need help with more in-depth mining research
September 2017 by Chris Ralph
How do I set up a Miller table?
What minerals are magnetic? I have heard that super magnets (rare earth magnets) can capture platinum. True?
Some fellow in Texas was selling a Spanish needle—a dousing device used to recover minerals in the old days. Do you know anything about these?
I know big mining companies use cyanide and other leach systems to recover gold from ore. Is this the only economically feasible way to recover the values?
Q: I was wondering how such a device could locate a rich gold vein in quartz, for example, since a metal like gold is non-magnetic.
Q: Graphite spray to prevent sticking when using cast iron molds
Q: Does a claim holder of a claim that has been under constant, active status since 1932 have any rights that owners of newer claims do not have? In other words, do I have any grandfathered rights that post FLPMA claim holders do not have?
