Mineral Technologies The art and science of separation

Whatever minerals a mining company is after, there has to be a process, or a chain of processes, of separation. From its origins 75 years ago extracting heavy minerals from the local sands on Australia's East coast, Downers Mineral Technologies business soon started developing its own equipment, started selling it to other mining companies and evolved into a process solutions specialist
