The black sand separation system

This is our black sand separation system. When concentrate contains some gold and we do not want to recover the small gold, but need some black sand, we are using the classic magnetic separation from one bowl to other bowl. The concentrate is first dried on the stove, then black sand is removed for our purposes.

The black sand removal for purposes of gold recovery is efficient with this method only if you have very small amount of concentrate.

With bucket large concentrates this method is very slow and not workable.

It is clearly explained to our clients in the program Start Your Own Gold Mine during the training time.
