Minimal Equipment Required to un earth Sapphires.
Petrol Powered Generator for rotary tumbler to process stone & dirt into specific sizes to be processed through the wash plant.
A wash plant that has a recycle water process and find the precious stones in the tray that's above the pulsator that flush the lighter stones and rubbish to the end into a waste bin.
Sapphires are heavier that normal stone and dirt will settle in the bottom of the wash tray.
Apologise not to see this on operating as a generator had technical difficulties only moments before to started to record! Typical!
Maybe next time I will put an operational video on YouTube!
Enjoy!
