It corresponds spatial modeling geometallurgical attributes which impact the performance of metallurgical processes.
The attributes that are typically considered are:
- Recovery and/or metallurgical extraction
- Hardness (work index)
- Acid consumption
- Feed mineralogy
- Leaching or bioleaching test (sequential copper assays)
As standard practice GeoInnova recommends in a local estimate, the use of simple low cost tests that are more abundant and have spatial correlation with complex, scarce and expensive metallurgical test in order to coregionalisate by cokriging a local estimate, that can be incorporated to mine planning .
