Golden Age of Gold Dredges
June 2002 by Frank Lorey IIIOver one hundred years ago, gold mining in California saw a radically new method tried out in the major rivers of the Central Valley. Large gold dredges floated lazily but noisily on the waters, bringing up the rich gravel from deep below. With none of today’s environmental restrictions on such methods, the landscape was reworked into a maze of patterns along the rivers.
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.
We are sad to say that one our most beloved writers, Ron Wendt, passed away on November 10, 2007.
A Wilfley table works best when all of the mineral being run across it (the pulp) is about the same size. For this reason, I took a good look at each of the samples.
I woke up on Sunday morning, August 10, to heavy smoke. I saw where it was coming from, but it seemed like it was a long way off so I thought I was okay for the time being.
When we last heard from Ernie, he was still in Honduras and we were anxiously waiting to hear how the set up and training went at the mine. It got a bit complicated after that.
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
I’m sure we all have, at some point in time, gone out detecting and ended up not having the success we thought we would have. Here are some helpful game-changers that work for me and may work for you, as well.
