Ground mineral data for AI particle-size report review
Ground and treated mineral products can have similar names with different stated measurement bases.
NAICS 327992 · Ground or Treated Mineral and Earth Manufacturing
Ground and treated mineral products can have similar names with different stated measurement bases. USGS publishes industrial mineral information. A contributor can build a precise exercise around the basis and sample reference that accompany a particle-size result. USGS industrial sand and silica context
Prepare a fictional milling-run record, sample ticket and original size-distribution table. State explicitly whether each exercise column reports retained or cumulative material. Ask the model to answer a customer request using the matching definition. Include a table missing its column heading and a similar product from another run. The key should preserve both gaps rather than infer the convention from the numbers.
Label mineral description, sample, method reference, unit and distribution basis. Hold out a different table order for evaluation. Score reversed cumulative interpretation, wrong-sample pairing and unsupported conversions separately. Any calculation should cite the exact exercise definition and inputs used in the reviewer key.
Use invented values and original reports without handling powders. Customer formulations, proprietary treatment conditions and laboratory documents require source-specific authority. Explain the report-reading task and independent review in the licensing brief. Confirm the buyer's accepted product and measurement scope before preparing more operating data.

Original Fiund exercise
A percentage below a threshold depends on weighting
The records contain fictional particle counts and masses. The exercise compares reporting definitions, not any real mineral.
| Record | Source | What it records |
|---|---|---|
| 1 | Count table | Eight of ten particles below toy threshold T. |
| 2 | Mass table | Below-threshold group weighs 2 units out of 10 total. |
| 3 | Request | Report percent below T on mass basis. |
Question for the model
Which result should be returned?
Show the reference answer and checks
Return 20% on a mass basis from record 2 (2 ÷ 10). Record 1 supports 80% on a count basis, a distinct result for the same fictional sample. Preserve both denominator definitions so the values are not treated as conflicting copies.
- Reporting 80% because the count comes first
- Comparing distributions with different weighting as equivalent
Fields to preserve
- threshold_id
- Names the shared cutoff
- weighting_basis
- Distinguishes mass from count
- denominator_total
- Stores the matching total for each calculation
Test another case
Provide two thresholds with the same numerical percent under different weightings; require matching both threshold and basis.
No actual mineral sample, exposure analysis, screening settings or material qualification.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
