Small-Scale Concentrating and Recovery Methods
April 2011 by Bill McCuskeyThe first step in my recovery process after milling the ore to the desired size is to table it. On this particular ore, I get good results milling it to minus 100 mesh.
The Alaska state government has been trying to keep up with and maybe even stay on top of the situation by studying the problems associated with rapid growth and how to solve them.

I have figured out over the years that the winning combination is hard work, persistence, knowledge, and a little luck. This leads me to describe one of my best finds ever, a “honey hole” of placer gold, if you will.
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.
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that may be present.
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.
