Boddington Bauxite Mine

Boddington Bauxite is situated within the Darling Range of Western Australia's Peel Region, approximately 130 km south-east of Perth. The terrain is characterised by lateritic plateau formations overlying Precambrian basement, with shallow bauxite horizons at 1–4 m depth. The region supports dense jarrah-marri forest, classified as a Dieback-sensitive zone under Phytophthora cinnamomi protocols. All contractor vehicle movements require mandatory hygiene station compliance and certified Dieback management plans prior to site access.

The operation is fully operational (24/7 continuous mining cycle), supplying bauxite ore to the Worsley Alumina refinery at Collie via a dedicated slurry pipeline. Key B2B demand drivers include:

• Diesel consumption: High-volume fleet of dozers, scrapers and haul trucks operating on uninterrupted rotations
• Dependence on grid-tied power substations for slurry pumping stations along the 51 km pipeline corridor
• Ongoing rehabilitation earthworks requiring civil and revegetation contractors
• Scheduled maintenance windows for mobile equipment and fixed plant

Bauxite extraction follows a selective dozing and reclaim circuit without conventional blasting. Crushed ore is conditioned and fed into a primary slurry preparation plant where particle size reduction and liquid-solid ratio control are critical. Key engineering parameters include:

• Slurry rheology management across 51 km pressurised pipeline
• High-wear lining requirements in pump casings and pipe bends
• Physicochemical dosing (flocculants, pH modifiers) at transfer stations
• Instrumentation and SCADA systems for real-time pipeline integrity monitoring

South32 Worsley Alumina operates under a robust Heritage compliance framework, with active consultation protocols with Noongar Traditional Owners across all mining lease corridors. ESG priorities shaping B2B procurement include:

• Mandatory Aboriginal Business procurement targets aligned to South32's Reconciliation Action Plan
• Progressive land rehabilitation certified to DMP standards post-strip
• Biodiversity offsets and Dieback containment as contractual KPIs
• Carbon intensity reduction targets linked to Scope 1 diesel fleet emissions
