Refractory and Complex Gold Ores Forum

View Program


The Forum is part of the Gold-PM sessions and commences 11:00am Friday 25 May.  It concludes with panel discussion and open Q&A chaired by Alan Taylor, Metallurgical Consultant/Managing Director, ALTA Metallurgical Services.

This forum features 8 technical papers covering characterisation of sulphide minerals, modelling of pyrite oxidation, salt roast direct leach of PGM ores, downstream behaviour of iron-arsenic POX products, commercial HITECC operation to combat pregrobbing, treatment options for double refractory material, expansion of a commercial POX operation, and continued development of the BIOX Process.

The final panel is a valuable opportunity for interaction with international presenters and delegates. Topics include technical/economics implications of increasing S:Au and Impurity: Au ratios in ores, trends in process technology for recent projects, progress in alternative lixiviants, prospects for new innovations such as METOXS® molten salt technology. status and prospects for collaborative R&D, plus questions/comments from the floor.
