This is what a buyer checks before they shortlist energy, mining, water and environment suppliers.
What does a mine operator check before selecting equipment or minerals?
For equipment they check duty rating and wear life against their ore; for mineral products, the assay specification and consistency. In both cases they check site support, because a mine is usually remote and downtime is measured in lost production per hour.
A plant metallurgist is evaluating a change that will be judged on throughput and unplanned downtime.

First, what the product is
The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Product type
Processing equipment, wear parts, reagents and mineral products differ.
- 2
Duty rating and capacity
Mining duty is far harsher than general industrial.
- 3
Wear material specification
Determines liner and wear part life.
- 4
Assay specification
For mineral products, the compositional guarantee.
- 5
Particle size distribution
Governs downstream processing behaviour.
- 6
Site support capability
Mines are remote and downtime is expensive.
- 7
Spare and wear part availability
The ongoing cost and the ongoing risk.
Then the paperwork
Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Technical specification and capacity dataAsked at: selection | Throughput, power and duty rating under stated conditions | Publish it |
| Certificate of AnalysisAsked at: every consignment | Assay and particle size for the mineral consignment | Per shipment |
| Wear life dataAsked at: equipment selection — the real cost measure | Expected life under stated ore conditions | Name it, share on request |
| Material certificate for wear partsAsked at: acceptance | Alloy composition and hardness of wear components | Per shipment |
| Safety Data SheetAsked at: site approval | Hazard and handling information for mineral products | Publish it |
| Site support and spares statementAsked at: purchase decision | Where support is based and what is stocked | Publish it |
| Reference installation listAsked at: risk assessment | Comparable operations using the equipment | Publish it |
The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.

Questions suppliers ask
Why does wear life dominate equipment selection?
Because in mining the consumable and maintenance cost usually exceeds the capital cost within a short period. A supplier who publishes wear life under stated ore conditions is competing on the number the metallurgist actually tracks.
How should assay guarantees be presented?
As guaranteed values with tolerances and the sampling method, not as typical results. Mineral contracts are settled on assay, and a producer who publishes the guarantee and the sampling basis is much easier to contract with.
What matters most about site support?
Where people and parts actually are, and how quickly they reach the site. Mining operations lose large sums per hour of downtime, so a specific support answer, with locations and response times, outweighs a keener price in almost every evaluation.
