1.Broken up and screen. Many alluvial gold deposits contain sticky mud clumps. Some of these clumps may have particle sizes greater than 100 mm. If these clumps are not broken up, the gold will be lost along with the waste rock during the screening process. In addition, the mud can cement on gravel or pebbles.
