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.

Scope and specifications
- Product type
- Processing equipment, wear parts, reagents and mineral products differ.
- Duty rating and capacity
- Mining duty is far harsher than general industrial.
- Wear material specification
- Determines liner and wear part life.
- Assay specification
- For mineral products, the compositional guarantee.
- Particle size distribution
- Governs downstream processing behaviour.
- Site support capability
- Mines are remote and downtime is expensive.
- Spare and wear part availability
- The ongoing cost and the ongoing risk.

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.
