Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Gravity Concentrating Tables

Now, for a gold pan, a very good panner can take a pan with 15 pounds of ore in it and pan it in 10 minutes. That is 1.5 pounds per minute, versus 100 pounds in 7 minutes, or 14.3 pounds per minute. The table is 10 times faster than a gold pan using theoretical situations. In reality it is more like 20-30 times more efficient than a gold pan.
