An extensive heap leach field test was conducted during the 1993-1994 winter season at Carmacks, Yukon Territory. The test utilized a 5-m-diameter crib loaded with composite ore from the Williams Creek deposit, stacked to a total height of 7 m. The Government of Yukon published the results, demonstrating the practicality of year-round heap leaching in extreme cold conditions.
Use Cases
- Model heat retention in heap leaching based on insulation and process heat data mentioned in the description
- Analyze leachate flow performance based on continuous operation from September to February
- Evaluate commercial heap design feasibility based on crib replication of an interior heap segment
- Assess supplemental heating requirements based on analysis of leachate temperature maintenance
Strengths
- Test conducted over a continuous period from late September through mid-February
- Specific operational parameters described, including crib diameter (5 m), heap height (7 m), and leachate temperature (21°C)
- Analysis includes ambient temperature extremes below -40°C and an average of -13°C
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
