How to Recognize Hard Rock Gold Ores
September 2017 by Chris Ralph
I regularly get inquiries along the line of: “Hey, I found this rock, and I think it might be gold ore. How can I tell?” Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.
Some will doubt its value given the ultra-fine particle size… Some will become encouraged about not having to incur significant time and expense to break rock.
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
The most commonly asked question in metal detecting is, “Which metal detector should I get?” People worry a lot about not getting the right machine. They do not want to waste their money and their time with the wrong metal detector.
Centrifugal bowls are very efficient, and with proper operation they can consistently achieve gold recoveries above 95% with gold of about 50 mesh size.
South African gold miners are turning their anger towards Britain, charging that the sale of 25 tons of gold by the Bank of England has depressed gold prices and put them out of work.
Another little gem of equipment he built was a nifty sample splitter. In order to get accurate assays, you need to have really good, representative samples for the assayer to process.
Take a look at the picture—it’s pretty simple and you can build it yourself.
