The analysis is focused on abrasive slurries, reduction of DE/EE, control of GE, operational robustness, and metallurgical accounting performance.

Technical Criterion	Equiprobabilistic Modular System (SMM)	Rating (0–10)	JKL MLH with Agitation	Rating (0–10)
Delimitation Error (DE) control	Full cross-stream cut, pure equiprobabilistic design	9.5	Internal cut on homogenized slurry	9.0
Extraction Error (EE) control	Increment fully captured, full-stream diversion design	9.5	Capture in internal chamber with hydraulic control	9.0
Segregation reduction (GE)	Depends on the upstream flow condition	7.5	High-intensity agitation prior to cutting	9.5
Fundamental Error (FE) control	Does not eliminate FE (theoretical; depends on sample mass)	8.5	Same theoretical limitation	8.5

OVERALL AVERAGE

• Equiprobabilistic Modular System (SMM): 8.8/10
• JKL MLH with Agitation: 9.1/10

TECHNICAL CONCLUSION

SMM Advantages

• More universal and flexible design.
• Lower mechanical complexity.
• Excellent performance under ISO/AMIRA standards.
• High statistical robustness if the flow is already stable.

SMM Disadvantages

• Does not correct upstream segregation.
• More dependent on the hydraulic condition of the line.

JKL MLH Advantages

• Reduces stratification before the cut (↓GE).
• Greater stability in horizontal lines handling dense slurries.
• Better performance under density fluctuations.
• Greater stability in metallurgical reconciliations.

JKL MLH Disadvantages

• Greater mechanical complexity.
• Higher CAPEX and OPEX.
• Requires wear control on agitators and the internal chamber.

Strategic Recommendation

• For systems where the flow is already stable and homogeneous, SMM is the optimum solution.
• For horizontal lines with risk of stratification, density variation, or heavy abrasive slurries, MLH is superior.
• For critical metallurgical accounting applications (payments, concentrates, contracts), MLH provides a slight technical advantage.

Comparative Radar Chart

• Equiprobabilistic Modular System (SMM)
• JKL MLH with High-Intensity Agitation

The chart clearly shows:

• MLH is superior in segregation control (GE), operational robustness, and stability for metallurgical accounting.
• SMM is slightly superior in cost efficiency and structural simplicity.
• Both are very close in DE and EE control, confirming that both are high-level sampling technologies.
