Energy in Mining | Sally Braham Public Relations

The electricity consumption is weighted towards the hard-rock, deep-level mines and the diesel towards the coal and iron ore producers. This is due to the greater number of opencast or open pit mines in coal and iron ore which use diesel earthmoving equipment as the prime means of moving the ore.

Environmental Risks of Mining

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
