Many years ago I spent a lot of time in university engineering libraries to persue all I could find on mining and the machines used for concentrating minerals.
Here you will find some of the results. Over the years some information has been lost, mostly the very early articles from such publications as the California Mining Journal.
The most important ones on placer mining, sluices, jigs and other gravity concentrating devices are here.
