Process Stage	Equipment	Model	Function
Primary Crushing	Jaw Crusher	PE 900×1200	Coarsely crushes run-of-mine ore (≤750mm) to ≤200mm; Capacity: 220–380 t/h
Secondary Crushing	Multi-cylinder Hydraulic Cone Crusher	HP300 (Standard Coarse Cavity)	Hydraulic motor adjusts discharge opening; 320 t/h; automatic tramp iron release (no shutdown required for clearing)
Fine Crushing	Multi-cylinder Hydraulic Cone Crusher	HP300 (Fine Cavity)	Hydraulic motor adjusts discharge opening (10–25mm adjustable); reduces secondary crushing product to ≤20mm; closed-circuit loop ensures proper feed size for grinding; inter-particle (lamellar) crushing principle yields excellent particle shape with minimal flaky/elongated particles
Screening	Circular Vibrating Screen	3YK2160 (2 units)	Three-deck screening to classify fine crushing product; top deck (>25mm) returns to fine crushing; middle deck (10–25mm) and bottom deck (<10mm) proceed to grinding circuit
First-stage Grinding	Wet Grate-discharge Ball Mill	Φ3200×4500	Wet grinds ore (≤25mm) to 55%–60% passing 200 mesh; Capacity: 45–55 t/h; achieves suitable fineness for roughing
First-stage Classification	Hydrocyclone Cluster	FX-500 (6 units)	Operates in closed circuit with first-stage ball mill; overflow concentration 32%–35%, ≥55% passing 200 mesh; coarse underflow returns to ball mill for regrinding
Second-stage Grinding	Wet Overflow-type Ball Mill	Φ2700×3600	Regrinds rough concentrate and middlings to >80% passing 325 mesh; ensures mineral liberation degree required for cleaning
Second-stage Classification	Hydrocyclone Cluster	FX-350 (4 units)	Operates in a closed circuit with the secondary grinding stage; overflow fineness: ≥80% passing -325 mesh; ensures full liberation of composite particles before entering the cleaning circuit
Agitation/Pulp Conditioning	High-efficiency agitation tank	Φ3000×3000 (4 units)	Pulp conditioning and reagent mixing; ensures thorough initial contact with flotation reagents (xanthate, No. 2 oil, lime milk); residence time ≥8 minutes
Roughing	Pneumatic flotation machine	SF-8 (10 cells)	Rapid flotation to recover the majority of liberated copper minerals; rougher concentrate grade: 8%–12%; roughing recovery: 75%–85%
First Cleaning	Pneumatic flotation machine	SF-4 (6 cells)	First stage of upgrading rougher concentrate; removal of gangue inclusions; concentrate grade raised to 16%–20%
Second Cleaning	Pneumatic flotation machine	SF-4 (4 cells)	Second stage of upgrading first-cleaner concentrate; further removal of silicate minerals; concentrate grade: 22%–26%
Third Cleaning	Pneumatic flotation machine	SF-2.8 (3 cells)	Final cleaning stage; ensures concentrate grade ≥26%; middlings returned to second cleaning to form a closed-loop circuit
First Scavenging	Pneumatic flotation machine	SF-8 (6 cells)	First scavenging pass on roughing tailings; recovery of residual copper minerals; scavenger concentrate returned to roughing feed inlet
Second Scavenging	Pneumatic flotation machine	SF-8 (4 cells)	Second scavenging pass on first-scavenging tailings; maximizes recovery; scavenger concentrate returned to first-scavenging feed inlet
Concentrate Thickening	Center-drive high-efficiency thickener	NZS-12	Thickens flotation concentrate (solids content 18%–22%) to 45%–55%; overflow water recycled to the grinding circuit
Concentrate Filtration	Ceramic filter \|	TT-60	Dewaters concentrated underflow to a moisture content of ≤10%; the filter cake is suitable for direct bagging and transport; filtration area: 60 m².
