lowest size at which diamond re-covery is usually attempted-! to 1 mm. At that time, the early 1950s, most heavy-medium cyclone plants used magnetite media, and so it was that a magnetite system was installed in 1955 to recover diamonds from the minus 6 mm ground at Williamson Diamond Mine in Tan-zania. An almost identical plant was
