Eco-Friendly Ore Processing Line: Low Energy, High Yield with Tailings Treatment
Introduction of Ore Dressing Line
A mineral processing plant (or beneficiation plant) is designed to extract valuable minerals from raw ore through a series of physical and chemical processes. The goal is to produce a high-grade concentrate while minimizing waste. This article covers the typical processing flowsheet, key stages, and advantages of modern mineral processing plants.
Capacity: 10,000-300,000 tons/year
Main equipment: ball mill, crusher, flotation machine
Service scope: Provide overall solution and equipment for mineral processing line
Ore Dressing Line Production Process
1. Crushing & Grinding
Primary Crushing: Large rocks are reduced to smaller pieces (100–250 mm) using jaw or gyratory crushers.
Secondary & Tertiary Crushing: Cone crushers or impact crushers further reduce ore to 10–20 mm.
Grinding (Ball Mill / SAG Mill): Ore is ground into fine particles (75–150 microns) for liberation.
2. Classification (Screening & Hydrocyclones)
Separates particles by size (coarse vs. fine) for optimal downstream processing.
3. Gravity Separation (Optional)
Used for heavy minerals (gold, tungsten, tin) via jigs, spirals, or shaking tables.
4. Froth Flotation (Key Step for Sulfides & Oxides)
Chemicals (collectors, frothers) help separate hydrophobic minerals (e.g., Cu, Pb, Zn) from gangue.
Flotation machines produce a mineral-rich froth for further refining.
5. Magnetic / Electrostatic Separation (For Iron, Titanium, etc.)
Magnetic separators recover magnetite or ilmenite.
Electrostatic separators divide minerals based on conductivity.
6. Dewatering & Tailings Management
Thickeners: Remove water from slurry.
Filter Presses / Centrifuges: Produce dry concentrate for transport.
Tailings Storage: Safe disposal or reprocessing of waste.
