01
Condition
Free gold portion is high and coarse liberation is visible
Recommendation
Start with gravity-first route using shaking table early
Operating reason
Early gravity capture reduces reagent load and eases downstream control.
Application guide / generalized scenario
A practical selection framework for Andean gold projects deciding between shaking table focus, flotation focus, or a hybrid route.

01 / Reference conditions
For this generalized scenario, assume that one composite pilot result may not represent texture changes between ore domains. Validate each proposed route against multiple domain samples.
This guide compares three front-end choices for 40-140 TPH projects using jaw crushing with gravity and flotation options.
02 / Selection logic
01
Condition
Free gold portion is high and coarse liberation is visible
Recommendation
Start with gravity-first route using shaking table early
Operating reason
Early gravity capture reduces reagent load and eases downstream control.
02
Condition
Gold is fine and associated with sulfides
Recommendation
Move to flotation-led route with tighter feed control
Operating reason
A gravity-only route may leave recoverable value in tailings; confirm with staged metallurgical tests.
03
Condition
Ore domains switch frequently within one month
Recommendation
Use hybrid route with clear operating mode transitions
Operating reason
Hybrid architecture gives resilience without forcing one route on all ore.

05 / Comparison matrix
Swipe or scroll horizontally to compare all three routes.
| Metric | Gravity-first | Flotation-led | Hybrid adaptive |
|---|---|---|---|
| Planning ore condition | Coarse free gold | Fine sulfide-associated gold | Mixed and shifting ore |
| Reagent dependence | Low | High | Medium |
| Recovery upside | Medium | High | High with flexibility |
| Operational complexity | Low | Medium | High |
| Main risk | Fine-gold losses | Cost pressure if ore coarsens | Mode-switch discipline gaps |
06 / Operating context
A single composite pilot sample may hide domain differences that affect route performance.
Use multiple domain-tagged test sets and map each result to the proposed route before final selection.
Teams make better decisions when suppliers present route performance under explicit ore domains rather than one blended benchmark.
If proposal language does not define liberation and reagent assumptions, the cost forecast cannot be validated.

Replace assumptions with data
Share the feed and product conditions that define the process. The guide provides a comparison frame; final equipment sizing still requires a project-specific check.
