    Preconcentration Of Copper Ores By High Voltage Pulses

    Aug 01, 2015 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.

    With metalliferous ores, the second sink product can be regarded as a scavenging stage for the dense minerals, thus increasing their recovery. This second product may be recrushed, and, after de-sliming, returned for retreatment. Where the separator is used for washing coal, the second stage cleans the float to produce a higher grade product.
