Old mine workings and tailing piles can represent opportunities on many levels, from the chance to simply find a nugget on up to the commercial reworking of the old tailings for profit.
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.
Over the last several months, starting from before I left for Australia, I’ve been working on getting all the 2011 paperwork done for my mining claims. I will admit that some parts of the paperwork I let go until only a week or two before the due date.
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.
I 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.
When it was all setup and running, you had everything coming off the dredge riffles into the boil box. At the hole section, some of the water got sucked down and pulled a lot of black sand and over heavies…
