Ore sorting: Efficiently optimise the treatment of ores in ...

By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.
