Prospecting & Detecting
Refractory Gold Processing
February 2013 by Thom Seal, PhD, PE
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.Prospecting for Pegmatites
…in some cases pegmatites have produced individual mineral crystals that are enormous, attaining lengths of over 40 feet long, and many of the world’s largest mineral crystals are examples that were found within pegmatite deposits.Forty-Six Nuggets
This past summer, a two-week adventure in Alaska and other gold prospecting trips turned out to be some of my greatest life experiences.
Old Mine Sites and New Technology
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
Recovering Fine Gold with Oleophilic Adhesion
Oleophilic means "affinity to or attracted to oils," and this includes gold an diamonds.
Introduction to Meteorites
The distribution of meteorites across the planet was, at one time, thought to be random and unpredictable.What is a Valid Mineral Discovery?
One of the greatest opportunities afforded to the citizens of our country is the right to stake and hold mining claims on federal lands. One doesn’t need to be a lawyer to stake mining claims, but a little bit of knowledge about mining claim laws can be helpful.
Proper Assaying of Placer Samples
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
