Small-Scale Processing of Hard Rock Ores
December 2014 by Chris RalphDepending 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.
With the high price of gold, there are many new prospectors out in the hills all over the United States, and while we would all prefer to be finding those larger nuggets, it doesn’t always work that way. Sometimes all that is available is nothing more than a few small flakes. The truth is, new prospectors are sprouting up all across the planet—especially in the developing nations.
You find yourself with a bucketful of concentrates that you have accumulated over the season and consider the logical next step: to reduce the bucket of cons to a gold bar. Where do you begin?
To get to the gold, the miners had to remove the shale pieces and stack them on the sides while sluicing the remaining material through their boxes.
The first thing a person should do is seriously consider whether they want to go mining as a hobby or a business, and the tax implications of the choice.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
We had been picking away at it, but the going was mightly slow. Why not use some explosives to advance a little quicker?
Some ask if a prospector can collect an entire ounce in a day. It is possible; I’ve done it before.
