Throw-Away Gold: Back to Basics
February 2002 by T.D. LaRune
Placer mining, whether for profit or recreational purposes, involves separation of free gold from the gold-bearing sands (gangue) of alluvial deposits by methods using specific gravity. The free gold can vary from 17 to 19.3 in specific gravity terms, depending on the alloy mix, which is usually silver, but can be copper, lead, sulfur, tellurium, antimony, or mercury.Additional articles that might interest you...

A New Prospecting Spot
October 2016
Once indicators start showing up along or below a contact I start to get excited. When I have shale, and outcroppings of diorite with iron-red, gritty soil and some clay thrown in, I really get lightheaded. I may be a mile away from the nearest diggings but that’s okay. I just found a spot that could provide some nice nugget hunting.

October 2011
I am trying to find any information about using bubbles to separate platinum from sands and small particles. I think it has to have a surfactant in the process. Do you know of this bubble tech?
