Introduction
Currently employeed as the Superintendent of Mineral Waste Management at Rio Tinto Iron Ore. Leading a small team and undertaking numerous studies with a particular focus on Acid and Metalliferous Drainage. I am leading several R&D projects at the moment including pit lakes, geochemical upscaling and storage of PAF under waste dump slopes.

Article

Rio Tinto Iron Ore (RTIO) manages eleven mines in the Pilbara region, Western Australia. Three of these mines have previously or are currently mining black shale that contains varying amounts of pyrite. Several new deposits currently being evaluated and existing mines that may progress below water table in the future, will also encounter this waste...
Article
An open limestone channel (OLC) was constructed within an existing drain to treat the acidic and metal-rich drainage waters generated from an acid sulfate soil (ASS) catchment. The OLC was constructed downstream of a catchment pump and it consisted of a series of ponds and limestone sections. The accumulation of sediment over the limestone, prevent...

This study developed an industry-applicable, thermal decomposition methodology for quantification of carbonate mineral acid neutralisation capacity (ANCtherm-carb) for waste rock, tailings, and other mined materials. Standard titration-based methods for ANC can be compromised due to contributions from silicate minerals, ion exchange, Fe-rich carbon...
Conference Paper
Full-text available
At many Rio Tinto Iron Ore sites in the Pilbara, current or planned mining activities will take place below the regional water table. Pit design and construction strategies used by Rio Tinto include limiting exposure of sulfides on the pit walls, thereby limiting exposure of the sulfides to oxygen. As a consequence, rates of sulfide oxidation and g...
Article
Full-text available
The principles of limestone drain systems that are commonly used to passively remediate acid rock drainage have been adapted and modified for remediation of acidic and metal-rich drainage that is produced from broad scale agricultural land use of regions underlain by Acid Sulfate Soils (ASS). The acidic drainage water from sugar cane fields in an A...
Article
Due to the episodic nature of rainfall and the high dissolved metal concentrations in the acid sulfate soil catchment of Clothiers Creek (NSW, Australia), active treatment was considered more appropriate than passive treatment. Alkaline reagents were added to oxidised shallow drains to remove acidities ranging from 438 to 1,837 mg/L CaCO3. A fine l...
Article
The water quality of drainage discharged via pumping from an acid sulfate soil (ASS) affected catchment used for sugar cane farming is temporally very variable and is influenced by the various rain event magnitudes, their antecedents, and the particular phase of the discharge in any rain event. Rainfall episodes can cause substantial changes in aci...
Article
Full-text available
Catchments that contain acid sulfate soils can discharge large quantities of acid and dissolved metals into waterways. At McLeods Creek in far northern NSW, Australia, the acidity from the hydrolysis of dissolved metal species, particularly aluminium and iron, contributes to greater than 70% of the total acidity. Therefore, a poor relationship exis...
Chapter
The generation and release of acidic water from acid sulfate soils are an environmental problem of international importance. This chapter focuses on the suitability of permeable reactive barriers packed with neutralizing agents such as calcite in the treatment technology for assisting in the management of drainage from acid sulfate soils. However,...
