Wonnerup Operations

Wonnerup Main is situated within the South West Mineral Field of Western Australia, near Busselton in the Geographe Bay coastal plain. The operation sits in close proximity to the Vasse-Wonnerup Wetlands, a Ramsar-listed ecosystem of international significance. Surface hydrology management is therefore a critical operational constraint, requiring engineered drainage controls, groundwater monitoring bores, and strict containment protocols to prevent saline or turbid discharge into adjacent protected waterways.

Currently classified as Operating, Wonnerup Main represents an active revenue-generating asset within Tronox's integrated Australian mineral sands portfolio. The operation demands a continuous and reliable local supply chain. Mechanical workshop services — including hydraulic repair, conveyor maintenance, and mobile plant servicing — are mission-critical to avoid unplanned downtime. B2B vendors capable of rapid-response field support within the South West region hold a decisive competitive advantage in supplier qualification processes.

• Wet concentrator plant (WCP) maintenance contracts
• Mineral separation plant (MSP) consumables supply
• Mobile fleet servicing (scrapers, dozers, excavators)
• Electrical and instrumentation (E&I) field services

Wonnerup Main employs a dry mining methodology using front-end loaders and scrapers to feed a primary wet concentrator. Material handling relies on an intensive network of overland conveyors transferring heavy mineral concentrate across variable terrain. These conveyor systems — subject to high abrasion from ilmenite, rutile, and zircon-bearing sands — require specialist belt vulcanisation, idler replacement programs, and precision alignment services. Engineering vendors must demonstrate capacity for both scheduled and emergency conveyor interventions to maintain throughput continuity.

• High-abrasion conveyor belt management
• Slurry pump and cyclone circuit maintenance
• Gravity and electrostatic separation equipment servicing

Operating within a Heritage-sensitive corridor, Tronox/Cable Sands is obligated under Western Australian Aboriginal Heritage Act provisions to maintain active consultation and site clearance protocols prior to any ground disturbance. B2B procurement strategies increasingly prioritise Indigenous Business Australia (IBA)-registered suppliers and Noongar-owned enterprises for civil, rehabilitation, and environmental monitoring scopes. Progressive landform rehabilitation — including topsoil reinstatement and native revegetation — is a contractual and social licence requirement, creating sustained demand for specialist environmental services vendors throughout the mine's operational life.

• Noongar heritage survey and monitoring partnerships
• Progressive rehabilitation and native seed supply contracts
• Environmental compliance monitoring (groundwater, dust, noise)
• Ramsar wetland buffer zone management services
