This gold ore beneficiation plant adopt two section of a closed-circuit crushing, stage grinding, stage flotation, concentration, filtration and dehydration process . 
Crushing: The raw materials are sent by vibration feeder into a 400 * 600 jaw crusher, after coarse crushing, the row of mines with finely row ore merger by belt conveyor to 1 1200 * 3000 vibrating screen, sieve products sent to 1200 medium-sized cone crusher finely crushed. Undersize product to 160 m3 in volume for two powder ore bin.   The final size of product are 15-0 mm  ore granularity . The automatic iron removal device and the metering device is on the Adhesive tape . 
Grinding &flotation: Two series, each series includes grid ball mill  1500 * 3000 mm and 1200 mm single spiral classification unit into a closed-circuit grinding, grinding concentration is  from 79% to 82%, 34-36% is  classifier overflow concentration and fineness of 59-62% - 200 mesh, a flotation using a roughing, second choice, a scavenging, sharing 5 a flotation machine 12 slots. 2 ball mill grinding using a 1500 * 3000 mm and constitute a closed circuit, two 250 mm hydrocyclone cyclone relief 25-28% concentration of 90% 200 mesh fineness. Secondary flotation  uses a roughing, secondary scavenging, selected three times and share 5 a flotation machine 16 slots. 
Dehydration: Uses concentration, filtration dehydration two pieces.
