In order to extract metals from the mined ore, the rock must first be crushed. This is today the most energy-consuming part of the process, but also crucial for which proportion of the available metal that can be extracted.
Another challenge is to extract a larger number of metals from complex ores in order to use the natural resource better. If more metals can be extracted, the volume of waste will also decrease.
Intelligent production systems, where you at an early stage separate waste rock from ore and where comminution of the rock is energy efficient and optimised for the following concentration process, will contribute to a decreased energy consumption and a better use of the natural resources.
