Miners feeding the sluice

Sluice is fed by miners by the rate of 132 shovels per hour where average shovel is about 8 kilograms, amounting to little bit more than one tonne per hour. In the first stage, slow water pressure and low slope is applied to review how much of gold is retained and what gold is eventually being lost.

Once capability have been attained, the slope is increasing up to the tolerated degree, and water pressure is increased. Up to 6-8 tonnes per hour may then be handled in the second stage.
