Lode or Placer: What Difference Does It Make?
September 2014 by Keith BowenThis explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
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 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.
Options for affordable crushers for small mining operations
I pulled out the nuggets I had worked on previously and looked at the size of the wire basket that the items to be cleaned are placed into. It looks much like a miniature french fry deep fryer.
There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
It all started with a phone call from my friend and prospecting partner Pat Keene. He told me that he knew of an investor who was just starting out in the gold industry and was looking for a gold consultant to go to Africa to prospect and analyze a 400 sq. mile concession in the middle of the Congo rainforest. I waited for the “just kidding” line...
