Dampier Salt

Project Logistics & B2B Overview

Geographic Location and Topography

Dampier Salt Pond is situated within the West Pilbara mineral field, Pilbara Region, Western Australia — one of the most geologically and logistically demanding environments on the continent. The operation leverages the region's extreme aridity and high solar radiation for solar evaporation brine concentration. The flat coastal terrain adjacent to the Indian Ocean is ideal for large-scale pond infrastructure, though persistent red-dirt particulate and abrasive airborne silica demand continuous filter maintenance across all mechanical and HVAC assets on site.

B2B Life Cycle and Operations

Dampier Salt Pond operates as a continuous 24/7 harvesting facility, cycling seawater through a staged evaporation pond network before mechanical harvest and stockpiling. Diesel-powered harvesting machinery, conveyors, and front-end loaders sustain uninterrupted throughput, creating a high-volume diesel consumption profile critical for fuel supply vendors. Dependence on dedicated power substations for pumping stations, lighting, and processing equipment makes electrical infrastructure reliability a tier-one procurement priority for the operating JV.

Engineering and Extraction Infrastructure

Unlike hard-rock circuits, Dampier's process chain centres on brine hydraulics and crystallisation kinetics rather than comminution. Key engineering assets include:

• Multi-stage evaporation pond network with controlled brine flow management
• Mechanical salt harvesters subject to high abrasive wear from NaCl crystal matrices
• Wash and screening plant for product-grade separation
• Conveyor and shiploading infrastructure at Dampier Port
• High-demand wear-part replacement cycles on harvester blades and screen decks

ESG, Value Chain and Sustainability

As a Rio Tinto-led JV, Dampier Salt operates under stringent Heritage compliance obligations aligned with the Aboriginal Heritage Act (WA) and Rio Tinto's post-Juukan Gorge cultural heritage framework. B2B vendors are increasingly required to demonstrate alignment with:

• Registered Aboriginal Business Directory WA participation or subcontracting commitments
• Scope 1 & 2 emissions reporting under Rio Tinto's net-zero pathway
• Marine environment protection protocols for brine discharge management
• ISO 14001-aligned environmental management systems
