Using Countercurrent Material Flow to Improve Gold Recovery Efficiency
December 2020 by Keith Bowen
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...
While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
Heading for Australia to metal detect for gold. Tips? Suggestions?
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.
The more experienced prospectors know these lesser known spots are the types of places where big finds are still made.
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
I got a signal but knew it was small. Still, I was very happy to find something. I continued and got another signal. Yes! A bigger nugget! Then I got another signal.
Feeling through the mud, I felt the weight and shape of what could only be gold. Throwing my hand in the water revealed a sixteen-gram nugget oozing with character.
