Preparing Ore Test Information for Equipment Selection
- Keep sample identity and sampling context with every result.
- Provide the complete laboratory report, not selected values.
- Define recovery, grade, water, power and tailings constraints.
- Mark assumptions that still depend on further testing.

Before requesting a mineral-processing equipment proposal, assemble the information you already have about the ore, intended product and test work. An ore name alone is not a sufficient equipment specification. This checklist helps organize the questions for your project team, testing laboratory and equipment supplier.

The information path
01 · Ore
Source, composition and variability.
02 · Sample
Sampling record and representative material.
03 · Test
Methods, conditions and reported results.
04 · Proposal
Review the process basis and equipment scope.
1. Identify the material and project stage
State the mine or material source, project country, target mineral or saleable product, planned feed rate and whether the project is a new plant or an upgrade. Attach existing assay and mineralogical reports, with their dates and sample references. Identify which information describes the whole deposit and which relates only to an individual sample.
2. Keep the sampling context with the results
Provide the sample source, collection method, preparation history and any information about variation across the material supply. Ask a qualified laboratory to advise on sample quantity, packaging and test scope. Do not select or ship a sample using an assumed universal quantity; requirements depend on the work being proposed.
3. Share the complete test report
Where test work exists, send the complete report rather than only a headline recovery figure. Ask the laboratory or project engineer to identify the test conditions, feed characteristics, product results and limitations relevant to equipment selection. Clearly distinguish preliminary observations from an agreed process-design basis.
4. Explain the operating constraints
Describe available electricity and water, planned operating hours, the site layout and existing equipment. Include the required product quality and the responsibilities for water, residue and site infrastructure. Ask the supplier to identify information gaps before comparing equipment configurations.
5. Check the proposal assumptions
A useful quotation should identify its feed basis, equipment list, technical scope, utilities, exclusions and inspection or acceptance arrangements. Ask how the proposal relates to the test results and what further validation is required. Capacity or recovery expectations must be discussed against the specific ore and operating conditions.
What to send with your enquiry
- Project country, location and development stage
- Ore source, target product and available assay or mineralogical reports
- Sampling records and full laboratory reports, if available
- Planned feed rate, operating hours and utility information
- Existing equipment, site constraints and the requested supply scope

Technical Decision Table
| Information | Why it is required | Selection use |
|---|---|---|
| Sample origin and method | Shows whether results represent plant feed | Defines confidence in design basis |
| Mineralogy and head grade | Describes mineral associations | Supports preparation and recovery stages |
| Crushing and grinding tests | Provide hardness and energy basis | Supports equipment sizing |
| Recovery testwork | Defines process response and products | Supports flowsheet assumptions |
| Water and tailings | Defines site restrictions | Influences recycling and disposal systems |
Final equipment selection should be based on confirmed material data, site conditions and the agreed technical scope.
Frequently Asked Questions
Can equipment be selected from a chemical assay alone?
Usually not. Assay results do not describe mineral associations, liberation size, hardness or recovery behavior.
What if testwork is preliminary?
A conceptual route is possible, but assumptions and remaining test requirements must be documented.
Why is sample traceability important?
Results are useful only when sample origin, collection method and relationship to future feed are understood.
