Nigeria 300 TPD Lead-Zinc Ore Beneficiation Production Line

NIGERIA-2019-METRO Machinery, a global leader in mining and mineral processing solutions, has successfully designed, supplied, and commissioned a 300 tons per day (TPD) lead-zinc ore beneficiation production line for a Nigerian customer, achieving an impressive 85% recovery rate.

This turnkey mineral processing project represents a significant milestone in METRO Machinery's expansion into Africa's growing mining sector, delivering a complete solution from primary crushing to final concentrate production.

Project Overview:

Project Name:300 TPD Lead-Zinc Ore Beneficiation Production Line
Location:Nigeria
Material:Lead-Zinc Ore
Processing Capacity:300 tons per day
Recovery Rate:≥ 85%
Plant Configuration:Complete beneficiation system (crushing – grinding – flotation – dewatering)

Complete Equipment List:

1.Feeding Hopper:Raw ore receiving and temporary storage
2.Primary Crusher:Coarse crushing of run-of-mine ore
3.Secondary Crusher:Medium/fine crushing for optimal feed size to ball mill
4.Vibrating Screen:Size classification and recirculation of oversize material
5.Belt Conveyors:Material transfer between processing stages
6.Ball Mill:Ore grinding to liberate lead and zinc minerals
7.Classifier (Spiral/Mechanical):Size classification of ground slurry – returns coarse particles to ball mill
8.Agitation Tank:Slurry homogenization and reagent mixing prior to flotation
9.Flotation Machine:Lead and zinc selective flotation separation
10.Dryer:Moisture removal from final lead and zinc concentrates
11.Roots Blower:Air supply for flotation machine aeration
12.Dust Collector:Environmental dust control and emissions management
13.Water Pump:rocess water supply and recirculation
14.Control System:Centralized PLC/electrical control for automated plant operation

Process Flow Overview:

• Crushing:Feeder + Primary Crusher + Secondary Crusher + Screen-Reduces run-of-mine ore to suitable feed size for grinding (< 10–15 mm).
• Grinding & Classification:Ball Mill + Classifier-Grinds ore to liberate lead and zinc minerals; classifier returns oversize for further grinding.
• Conditioning:Agitation Tank-Mixes slurry with flotation reagents (collectors, frothers, modifiers).
• Flotation:Flotation Machine-Selective flotation of lead and zinc minerals into separate concentrates.
• Dewatering:Dryer-Removes moisture from final concentrates for transport and smelting.
• Support Systems:Roots Blower + Dust Collector + Water Pump + Control System-Air supply, environmental protection, water management, and automated operation.

Recovery Rate Achievement: 85%

The 85% recovery rate is a testament to METRO Machinery's expertise in mineral processing engineering. Key factors contributing to this high recovery include:

• Optimized Grinding Circuit:Ball mill + classifier configuration ensures ideal liberation size for lead and zinc minerals.
• Advanced Flotation Design:Proper cell configuration, aeration control, and reagent addition points maximize selective recovery.
• Precise Process Control:Centralized control system maintains stable operational parameters
• Tailings Management:Efficient classification minimizes metal loss to tailings.
