Finally, when a concentrated mineral is dispersed, the exergy content decreases. A mine loses its natural exergy when the ore grade declines through extraction, and becomes zero when this ore grade equals to that of the surrounding environment. But exergy only represents the thermodynamic minimum. And this minimum is very far removed from reality.

Executive summary

In recent years ore quality has continued to fall across a range of commodities. For example, the average copper ore grade in Chile declined by 30% over the past 15 years. Extracting metal content from lower-grade ores requires more energy, exerting upward pressure on production costs, greenhouse gas emissions and waste volumes.

How do we extract minerals?

The primary methods used to extract minerals from the ground are: Underground mining Surface (open pit) mining Placer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
