Ore or overburden

The service life of liners in mining trucks varies depending on the abrasiveness of the hauled materials. The minerals present in the ore determine the aggressiveness of the wear. However, there are exceptions to this rule. For instance, in cases where quartz content is high, the service life may still be relatively long. This can be attributed to the low toughness of the rocks, which, despite containing hard minerals, are more likely to collapse or pulverize under pressure rather than cause aggressive wear.
