The Basics of Froth Flotation
June 2015 by Chris RalphI thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
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.
They must have assumed the paystreak was spotty and had been mined out, so they never mined as close to the side of the valley as they should have.
The 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.
With the recent surge of interest in gold projects, it’s about time to revisit a subject that strikes fear into the hearts of small-scale miners: Permits.
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
…there is an easy way to create a reasonably accurate map without any fancy instruments.
