1. Raise the pan out of the water. Make sure there is about an inch of water left in the pan. The water is necessary because you will continue to sift the sand from the gold when the pan is taken out of the stream. 2. Tilt the pan towards you slightly. Swirl the water and materials slowly in a circle.

The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can be inserted. The explosives are set off, and the iron ore is blasted out of the rock.

The 3 most common commercial biomining processes are: 1. Slope Leaching. Fine ore is kept in a large, slope-shaped dump. During slope leaching, a water solution made of inoculum is continuously sprayed over the ore. After that, the leach liquor (or remaining liquid) is gathered at the bottom and processed for supplemental metal recovery. 2.
