Mineral Concentrating Jig

Good source for mineral concentrators. http://graymfg.com/mineral.html
Delta Duplex Mineral Concentrating Jigs for sampling and production.
Jigs reduce the overall quantity of the raw ore down to the heavy minerals that are contained in the original ore.

Here's a few pics of my home-built jig. It runs on 12V.


The screen box, and infeed hopper are easily removed to facilitate cleaning. The screen box is about 4" x 14", and the hutch has a hopper bottom that funnels the cons down to a 3/4" exit pipe that can be equipped with a hose. Usually I just remove the cap to empty the hutch. The jig uses a sawtooth waveform with a very fast pressure stroke, and long, smooth suction period. It will handle about 300lbs/hour of 1/2" minus material. The diaphragm chamber is a section of 8" PVC pipe. I made the flanges by flattening pipe in the wife's oven, and then turning them on a rotary table on the mill.
I mainly use it prospecting for gems.
