How To
Enrichment of Mineral Deposits by Weathering—Part I
March 2016 by Chris Ralph
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.
Small-Scale Hard Rock Production
So far this year we have recovered over three pounds of gold and the hard rock veins seem to go on forever. We now have three claims that can produce good enough gold to set up a productive operation.
Prospecting for Diamonds in Kimberlite
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
The Fire Assay of Carbon
Carbon, activated charcoal, or “char,” as some old timers refer to it, can be an assayer’s nightmare.
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.
Recovering Fine Gold with Oleophilic Adhesion
Oleophilic means "affinity to or attracted to oils," and this includes gold an diamonds.

• Two questions: Is fool's gold magnetic? And how do you go about filing a miing claim?
Small-Scale Hard Rock Mining With Water Recycling
Once I have established the presence of gold in the sample, I collect five-gallon bucket quantities of the rock material for processing back at my shop.
