Liberation vs Grind Size
The tradeoff between freeing silver-bearing minerals and creating unnecessary fines.
Mine-to-refinery note: mineralogy, site conditions and the approved flowsheet determine real operating requirements. This site explains system relationships rather than field procedures.
What this topic covers
The tradeoff between freeing silver-bearing minerals and creating unnecessary fines.
Core mine-to-refinery ideas
Mineral liberation generally improves as particle size decreases.
The economically useful grind is determined by metallurgical testing rather than a generic target.
Ore domains can require different grind strategies.
Important tradeoffs
Finer grinding can improve liberation but increases energy and can create difficult fine particles.
Measurement and accounting
Classification and screening help control the size distribution entering downstream processes.
Lifecycle perspective
Machine operation, clearing and lockout procedures are not provided.
