Hannah Kitchener's insight:

SELFRAG has already demonstrated that one avenue to follow may lie in electro- fragmentation of particles, a technology which haas consistently been demonstrated on a batch process basis but which has yet to be proven on a commercial basis for large scale continuous processing. However, Alan's company, AngloGold Ashanti is watching the technology with interest, and SELFRAG 's Klaas van der Wielen says large scale commercialisation is planned for 2016 or 2017 (see MEI Online for full story). This is undoubtedly exciting innovative technology, and in this afternoon's session Dr. van der Wielen presented a number of relationships to describe high voltage breakage behaviour of an ore. Based on these relationships, a standardised methodology was outlined for single particle testing that allows for assessment of weakening and size reduction and the optimum generator setup.

Hannah Kitchener's insight:

SELFRAG, supplier of high voltage pulse power fragmentation equipment to geoscience, mining, recycling, and solar industries and institutes, has expanded its global distribution network with the appointment of Chinese distributor, Beijing euSCI Technology. With immediate effect, Beijing euSCI Technology will act as the official distributor for SELFRAG’s laboratory batch equipment in mainland China, as well as the territories of Hong Kong and Macau. The Beijing-based company has been a supplier of geoscientific laboratory equipment for over ten years and has strong links with major institutes throughout China.

Electrical comminution promises lower power costs and more efficient liberation
Hannah Kitchener's insight:

A Swiss company aims to send a jolt through the mineral processing sector. Selfrag AG has completed the pilot-scale engineering for an ore pre-treatment system that could lower the power draw of comminution by double-digit percentages. Using electric pulse fragmentation to weaken ore before it enters the milling circuit can speed up the grinding process and improve liberation results, according to research conducted with the Julius Kruttschnitt Minerals Research Centre (JKMRC).
