Electric Pulse Fragmentation (EPF) is an innovative technology that uses High-Voltage Pulsed Power (HVPP) for the selective comminution of a material. This paper aims to compa...
SELFRAG AG has developed a flexible pilot scale Pre-Weakening Testing Station (PWTS) using high voltage pulses (HVP). This provides a unique opportunity to investigate the machine setting conditions on ore breakage behaviour. A joint campaign was undertaken by the Julius Kruttschnitt Miner...
A novel technique using high voltage pulses (HVP) for ore pre-concentration has recently been reported. The technique utilises metalliferous grain-induced selective breakage and size-based screening to separate the feed ore by grade. Four copper-gold ore samples were tested to demonstrat...
