magnetic separation meant a dry process, which was not practicable for Witwatersrand ores. The advent of wet high-intensity separators13 revived NIM's interest in magnetic separation, and a small batch-type separator (Eriez model HIW4L) was purchased in 1967, and this enabled exploratory tests to be done on many ores and residues.
