Join the Southern Queensland Branch and AusIMM Metallurgical Society for the 2026 GD Delprat Distinguished Lecture: Flotation – understanding particles, processes and people.

About this event

Guillaume Delprat, along with Charles Potter, developed the first industrial froth flotation process in 1904 in Broken Hill to overcome the sulphide problem experienced at the BHP mines. One can only imagine the tremendous pressure Delprat (the General Manager) was under from his board and shareholders as the ore became more difficult to treat, recoveries deteriorated, and profits dwindled. He could have sought the comfort of an easy way out, but his innate curiosity, intellect, and strength of character would not permit him to seek a “Jim’s mowing franchise” of the day. He had responsibilities that he had to take care of.

In Delprat’s honour, we have heard from the likes of Mike Nelson, Alban Lynch, Graeme Jameson, Bill Johnson, Tim Napier-Munn, Joe Pease, and Peter Munro (to name but a few).

The Southern Queensland Branch and AusIMM Metallurgical Society invites you to attend the 2026 Delprat Lecture, a distinguished lecture series that provides minerals industry professionals an opportunity to showcase their perspective of a chosen topic in Minerals Processing.
