The scale of these hydraulic workings can vary; some are relatively small and were used on small creeks, while many of these areas are massive and can be seen from miles away. Gold can be found anywhere in hydraulic pits, but some investigation of the area can help you determine the best places to look. If you study the terrain, you can often find the areas where to monitors were set up. There ...
Get PriceThey do an excellent job of recovering small gold particles, even with a fairly high feed rate. It has been demonstrated that a simple shaking table is an environmentally friendly method of recovering finegrained gold from both placer and hard rock gold ore. Such tables can have a significant role in the reduction of the use of mercury by smallscale miners by providing them .
