Doctoral researcher Dyllon Randall, of the Crystallisation & Precipitation Unit in the Department of Chemical Engineering, beat presenters from around the globe to win the prize for best technical paper at the International Mine Water Conference, held in Pretoria in October.

The award was made by the Water Institute of Southern Africa (Mine Water Division) and the International Mine Water Association, and hopes to attract young engineers to mine water management.

Randall's paper was titled Seeding for selective salt recovery during eutectic freeze crystallisation.

His supervisor, Professor Alison Lewis, recently received the best-paper prize at the Water in Mining Conference in Australia, for a paper they co-authored.
