Engineering Contradiction Analysis
1Productivity
If conventional separate processes are used for flocculating settling, dense dewatering and tailings solidifying, then each process can be independently optimized, but the device complexity increases and processing efficiency decreases
Solution Approach 1:
The patent combines flocculating settling, dense dewatering, and tailings solidifying processes into a single integrated device. The reaction tank serves as a common chamber where all three processes occur sequentially or simultaneously, eliminating the need for separate equipment for each process while maintaining independent control over each stage through controlled addition of flocculants and solidifying agents.
Solution Approach 2:
The reaction tank is designed as a multi-functional vessel that can perform flocculating settling, dense dewatering, and tailings solidifying operations. The same tank accommodates different process stages by varying the addition of chemicals and operational parameters, making the device universal rather than requiring specialized equipment for each function.
2Productivity
If superfine tailings with small particle granularity are processed, then mineral processing efficiency improves, but safety risks to tailings dams increase due to low concentration
Solution Approach 1:
The device changes the concentration parameter of tailings slurry through controlled flocculation and solidifying processes. By adding flocculants and solidifying agents in controlled amounts, the system transforms low-concentration superfine tailings into high-concentration or solidified tailings, thereby improving both processing efficiency and tailings dam safety.
Solution Approach 2:
The patent replaces purely mechanical settling processes with chemical-flocculation-based processes. Instead of relying on gravitational settling alone for superfine particles, the system uses flocculants to aggregate particles and solidifying agents to stabilize the tailings, creating a more reliable and safe tailings management system.
3Ease of manufacture
If low-concentration tailings slurry is discharged directly into tailings pond, then processing costs are reduced, but safety hazards increase
Solution Approach 1:
The device performs preliminary flocculation and solidifying treatments on tailings slurry before discharge. By pre-treating the low-concentration slurry with flocculants and solidifying agents in the reaction tank, the system converts it into a safer form suitable for tailings pond discharge, eliminating the need for expensive subsequent treatment while reducing safety hazards.
