Pre-concentration of copper ores by high voltage pulses ...

The JKMRC has recently reported a novel ore pre-concentration method using high voltage electrical pulses (Part 1 of this paper). The technique utilises metalliferous grain-induced selective breakage under a controlled pulse energy input, and size-based screening to separate the feed ore into body breakage and surface breakage components, leading to ore grade splitting.
