The gold washing plant adopts the simplest processing method, first using a rotary scrubber washing machine for ore washing and screening, and then enriching the gold ore through sluice box. The production line process is simple and easy to operate, but the efficiency is high, and can achieve a recovery rate of over 80%, which is very suitable for large-scale alluvial gold mining. Note: If the original ore contains more sand and gravel but less mud lumps, trommel screen washing machine can be used instead of rotary scrubber.
