In Current years, Tailings dry discharge is a gradual emerging new tailings treatment process. It means the tailing pulp from dressing plant through multi concentration, then use dewatering vibrating screen to treat and get low moisture, easy sediment solidify and good for stockpiling slag. Slag can be transport to fixed position for dry stockpiling.
Application
Concentrate and dry the tailings from dressing plant, then reach the aim of dry stockpiling. It is good for the environment.
Process introduction
1. combination of hydrocyclone and dewatering vibrating screen: after concentrated by hydrocyclone, the underflow feed into high-frequency vibrating screen for dewatering. Then the tailings moisture will lower than 16%. The overflow from hydrocyclone and fine particle from dewatering screen underflow feed into thickener, filter press for dewatering. At last, the tailings are dry discharged.
2. directly use thickener and filter press to filter: this type need a huge investment at early stage and the range of application is small. Sometimes, it can't meet the production efficiency or dewatering degree.
Advantage of hydrocyclone + dewatering vibrating screen:
1. mature technology, good dewatering effect. The final tailing concentrate can up to 85% and meet the dry discharge requirements.
2. low operating cost. Our special equipment combination only need less equipment and civil investment. And jinpeng patent equipment have good dewatering effect, energy-saving, long service time and lower production cost.
