Mineral Liberation Analysis
 
 
 
The purpose of this analysis
 
Analysis SEM-MLA is used to understand how metals are present in the rock And and at what grind size the metals can be liberated.
 
 
 
This analysis serves as an important link between concentration data (chemical analysis results) and concrete processing decisions.
 
 
 
What SEM-MLA answers
 
 
 
SEM-MLA helps answer questions such as:
 
 
 
 
Is the metal already free or is it still locked in other minerals
 
 
 
 
How fine does the material need to be ground in order for the metal to be released
 
 
 
 
Is the grinding that has been done sufficient or not
 
 
 
 
 
What is analyzed
 
 
 
 
The relationship between metals and their binding minerals
 
 
 
 
grain and particle size and the location of the metal
 
 
 
 
The degree of metal liberation at a specific grinding size
 
 
 
 
 
(SEM-MLA is a mineralogical analysis, not a grade analysis.)
 
 
 
How the analysis is carried out
 
 
 
 
Samples are specially prepared and polished
 
 
 
 
The analysis is performed using Scanning Electron Microscope with Mineral Liberation Analysis (SEM-MLA)
 
 
 
 
Data is processed to show metal liberation and particle size distribution
 
 
 
 
 
Operational information
 
 
 
 
Number of samples: usually ≥ 100 grams
 (final requirements depend on particle size, material complexity, and scope of analysis)
 
 
 
 
Duration of work: ± 7–14 business days
 
 
 
 
Terms and conditions apply (material type and sample conditions may affect the scope and duration of the analysis)
 
 
 
 
 
Cost & sample delivery
 
 
 
 
The analysis fee does not include the cost of sending the sample to us.
 
 
 
 
All costs and risks during shipping are borne by sender's responsibility
 
 
 
 
 
Value added services
 
SEM-MLA more than just laboratory analysis.
 

Results include practical interpretation by mineral processing expert, to help you understand:
 
 
 
 
Is the problem with the grind size
 
 
 
 
Is the low process yield due to metals not being released
 
 
 
 
Is it necessary to use finer grinding or another process approach
 
 
 
 
 
When to choose SEM-MLA
 
 
 
 
If the metal content is already known but the process yield is still low
 
 
 
 
If you want to determine a realistic target grind size
 
 
 
 
If you want to avoid processing strategy errors
 
 
 
 
 
SEM-MLA is not used for
 
 
 
 
Determine the level or economic value
 
 
 
 
Replace metallurgical testing
 
 
 
 
Guarantee a specific recovery rate
 
 
 
 
 
One-sentence summary
 
SEM-MLA indicates the grind size at which metal can be released, thereby helping to determine the appropriate processing strategy.
