In the field of mineral processing, gravity separation technology has always occupied a core position due to its low energy consumption and high cost-effectiveness. As a technical expert who has been deeply engaged in mineral processing EPCM+O services for 20 years, we will analyze the systematic solution to improve gravity separation efficiency for you through practical experience, and help mineral processing plants achieve a technological breakthrough of increasing recovery rate by 10%-25%.
1.1 Precise particle size control
A three-stage crushing system (jaw crusher + cone crusher + high-pressure roller mill) is used in the crushing stage to strictly control the ore particle size within the ideal range of 0.3-3mm
Multi-layer high-frequency vibrating screen (screen aperture error ≤ 0.05mm) is configured to ensure that more than 95% of the ore reaches the target particle size
Case data: Through particle size optimization, the jig processing capacity of an iron ore plant has increased by 40%
1.2 Efficient desludging process
The hydrocyclone group (Φ150+Φ75 combination) is used to achieve a -0.074mm fine mud removal rate of >85%
Configured with an intelligent flocculation system (PAC+PAM composite reagent), the slurry concentration can reach 35%-45%
Key indicators: After desludging, the viscosity of the slurry is reduced by 30%, and the separation efficiency is significantly improved
2.1 Jigging machine intelligent upgrade solution
Adopt servo motor drive system to achieve 0.5-5Hz stepless frequency modulation
Innovative double-peak waveform design, bed looseness increased by 25%
Add ultrasonic bed monitoring system to provide real-time feedback on mineral stratification status
2.2 Centrifugal field enhancement technology
New horizontal centrifuge (G value up to 300G) to process -0.1mm fine-grained materials
Dynamic water film control system, concentrate grade is stable at more than 95%
Energy consumption comparison: 40% lower energy consumption than traditional shaking table
Parameter dimension control range efficiency influence coefficient
Water flow rate 0.8-2.5m/sΔ1m/s=±12% recovery rate
Medium density 1.2-3.5g/cm³Δ0.1g/cm³=±8% grade
Stroke frequency 100-400 times/minuteΔ50 times=±15% processing volume
Note: Establish parameter response model through DOE experimental design to achieve multi-variable collaborative optimization
4.1 Magnetic-gravity combined process
Pre-weak magnetic separation (0.3-0.5T) removes magnetic minerals and reduces the load of the gravity separation system
Typical case: A tungsten mine uses this process, and the gravity separation recovery rate is increased from 68% to 82%
4.2 Intelligent medium system
Intelligent compensation system for resuspension density (accuracy ±0.01g/cm³)
Closed-loop circulation system with medium recovery rate>98%
Cost comparison: medium consumption is reduced by 70%
Build a three-level control system composed of PLC+SCADA+AI algorithm:
Real-time monitoring of 12 key parameters (flow, density, particle size distribution, etc.)
Adaptive adjustment system response speed <0.5 seconds
Big data analysis platform provides process optimization suggestions
Implementation case: A gold mine has increased its annual revenue by 2.3 million US dollars through digital transformation
Adopting a two-stage gravity separation + three-stage scavenging process design, the recovery rate is increased by 15-20 percentage points
Configure online particle size analyzer (Malvern Insitec series), dynamically adjust process parameters
Establish a preventive maintenance system, equipment operation rate> 95%
