Metallurgy is the study of the process of separating and concentrating raw materials. It includes all the physical and chemical processes used to produce minerals and materials. Metal smelting methods are mainly divided into two categories: pyrometallurgy and hydrometallurgy. Slurry pump for metallurgy is mainly used in metal beneficiation and hydrometallurgy.
· Definition: The process of transporting solid-particle-laden slurry using slurry pumps, connecting various processes such as beneficiation, flotation, and tailings treatment.
· Application Scenarios: Metal ore beneficiation, froth flotation, tailings slurry transportation, and wastewater treatment.
Advantages and disadvantages of Hydrometallurgy
Advantages：
1) Able to handle raw materials of various grades;
2) Can handle complex mineral raw materials;
3) The effect of comprehensive recovery and utilization of multi metals is good;
4) Less smoke pollution.
Disadvantages：
1) Low production capacity, huge equipment and high cost;
2) High energy consumption;
3) There are pollution and treatment problems of wastewater and waste residue.
1. Beneficiation Process
Description: After ore crushing and grinding, slurry is transported to flotation or gravity separation processes via slurry pumps.
Recommended Products: Horizontal Slurry Pump, ZGB Slurry Pump.
2. Flotation Process
Description: Froth slurry in flotation needs stable transport without clogging to ensure process efficiency.
Recommended Products: Froth Pump.
3. Tailings Treatment
Description: Tailings slurry is transported from beneficiation plants to tailings storage facilities, requiring pumps with high head and wear resistance.
Recommended Products: Dredge Gravel Pump, ZGB Slurry Pump.
4. Waste Material and Flue Gas Desulfurization
Description: Slurry generated during metallurgical processes or flue gas desulfurization requires pumps with excellent corrosion resistance.
Recommended Products: FGD Pump.
5. Slurry Pits and Deep-Well Transportation
Description: Special scenarios such as slurry pits and underground mine transportation demand submersible operations.
Recommended Products: Submersible Slurry Pump.
· Severe Wear and Corrosion: High-density solid particles and corrosive fluids significantly wear down equipment, increasing maintenance costs.
Difficulties in Transporting High-Concentration Slurry: Poor slurry fluidity can clog pump channels, reducing efficiency or causing downtime.
· High Energy Consumption: Transporting dense, high-head slurry requires energy-efficient equipment to reduce operational costs.
· Environmental Pollution Risks: Improper handling of hazardous tailings slurry may harm ecosystems and increase environmental expenses.
· Clogging and Operational Instability: Uneven particle distribution or froth in the slurry can cause pump clogging or cavitation, disrupting production.
· Frequent Maintenance and Downtime: Harsh working conditions lead to frequent repairs, extending downtime and lowering productivity.
· Diverse Process Requirements: Each process, such as beneficiation, flotation, and tailings treatment, demands different pump performances, necessitating customized solutions.
