Introduction
The application of slurry pump in gold mine mainly includes gravity separation and flotation. Gravity separation uses the difference in specific gravity between gold and other minerals to separate, while flotation makes gold float by adding chemical reagents.

Gravity separation
Application process
Put the gold-containing ore sand into the drum screen and flow the ore through high-pressure water. The gravel sand larger than the sieve hole is transported to the tailings field through the sluice and belt; the ore sand smaller than the sieve hole is input into the 1-3 stage circular jig through the public distributor, and the concentrate of the 3-stage jig flows into the shaking table by gravity, and the coarse, fine and sweeping selection is carried out to produce fine gold.

Advantages
Gravity separation technology is simple and low in cost, and it is effective in capturing monomer rented gold particles, so it occupies a dominant position in the extraction of gold from placer mines. In recent years, this technology has developed rapidly in the extraction of gold from rock gold mines and has been widely used both at home and abroad.
Application process
The crushed ore enters the ball mill to be ground into ore pulp, and then enters flotation. Sodium carbonate is used as an adjusting agent in flotation to make gold float, while butyl xanthate and amine black medicine are used as recovery agents to separate gold ore powder from slag and produce gold concentrate powder.

Advantages
Flotation is suitable for processing coarse and medium-grained natural gold iron ore with high recovery rate. Mercury plates are added after grinding for gold recovery, and the recovery rate can reach 30-45%. Flotation is carried out through the overflow of the classifier. A certain concentration of sodium carbonate, caustic soda, etc. is added during grinding, which can make the mercury gold recovery rate reach 70%.

Conclusion
Slurry pumps are widely used in gold mines. Whether it is gravity separation or flotation, they play a key role in transportation. Its strong transportation capacity, good wear resistance and simple operation make it play an important role in gold extraction from gold mines.
