Dr Tong joined Intec early in 2004, after completing a PhD and with extensive research chemistry experience, with particular emphasis on analytical inorganic topics and the numerous techniques for the characterisation of solids.

Within Intec, Andrew has worked principally on metal recoveries via the Intec Polymetallic Process for Hellyer tailings, including cementation, zinc electrowinning and iron and copper precipitation. This work was funded in part by an Australian Research Council Linkage Grant in conjunction with the University of Sydney's Chemical Engineering Department.

Andrew now manages the Intec Research Laboratory, which provides external clients with scoping testwork, ensures a solid basis for industrial scale processing, and continues to explore the complex chloride chemistry at the heart of the Intec Processes.

In addition to the Intec Polymetallic Process and Intec Gold Process, Andrew is coordinating further work on the Intec Metalliferous Process, which explores the use of chloride leaches on predominantly oxide (rather than sulphide) feeds. Examples of its application Electric Arc Furnace dust and zinc ferrites and nickel laterites.
