Too Slow: If the water flow is too slow, lighter particles won't get washed away, making it difficult to distinguish and separate the gold. Too Fast: If the water is flowing too quickly, even gold particles may get swept off the table. Thus, achieving a balance in the water flow is essential for effective recovery. Table Angle
