1500 TPD Molybdenum Flotation Plant in China

Crushing Section:

Three-Stage Crushing Circuit to reduce run-of-mine ore to below 12 mm.

Primary Jaw Crusher.

Secondary Cone Crusher in closed circuit with a vibrating screen.

Tertiary Cone Crusher for fine crushing.

Flotation Section:

Rougher Flotation: One stage of rougher flotation cells to produce a primary molybdenum concentrate and discard initial tailings.

Scavenger Flotation: Tailings from the rougher stage are treated in a scavenger flotation circuit to recover additional values, ensuring high overall recovery.

Cleaning Circuit: The rougher concentrate undergoes multiple stages of cleaning (typically 3-5 stages of cleaner flotation) to progressively upgrade the concentrate to the target grade of ≥55% Mo. Re-grinding of cleaner tailings or middlings may be incorporated.

Selective reagents (collectors, frothers, and depressants for gangue minerals like copper and iron sulfides) are carefully controlled via an automated dosing system.

Auxiliary & Control Systems:

Process Water Circulation and Reclaim System.

Reagent Preparation and Automatic Dosing Station.

Comprehensive PLC-based Process Control & Monitoring System for optimal and stable operation.

Dust Collection systems at transfer points and crusher stations.

On-site Laboratory for routine process control checks.

Grinding & Classification Section:

Two-Stage Ball Milling Circuit.

Primary Ball Mill in closed circuit with a spiral classifier.

Secondary Ball Mill operates in conjunction with a hydrocyclone battery to achieve a target grind size of 74 µm (D80).

Concentrate & Tailings Handling:

Concentrate Dewatering: The final high-grade molybdenum concentrate is thickened in a high-rate thickener and further dewatered using a filter press to produce a damp filter cake suitable for transport and sale.

Tailings Management: Final flotation tailings are pumped to a deep cone thickener for water recovery. The underflow (dense tailings) is transported to a designated tailings storage facility (TSF) for safe, dry stacking or conventional disposal.
