Fusion was engaged to design and fabricate a chemical storage solution for the Three Mile Hill Gold Mine in Western Australia. The requirement: a robust, corrosion-resistant tank to safely store caustic liquor in an outdoor mining environment.
We selected UV-stabilised PP-H (polypropylene homopolymer) sheet for the tank construction. Standard beige PP-H is a widely used thermoplastic in chemical storage due to its excellent chemical resistance, weldability, and cost-effectiveness. However, its performance degrades under prolonged UV exposure—making it unsuitable for long-term outdoor applications.
The UV-stabilised PP-H variant used in this project retains all the mechanical and chemical resistance properties of standard PP-H but includes additives that significantly enhance resistance to UV-induced degradation, such as brittleness, chalking, and discolouration. Importantly, the material remains beige in colour, allowing for seamless aesthetic and functional consistency with existing systems.
Fusion’s in-house fabrication team built the tank to suit site-specific space, access, and capacity requirements. The final result is a durable, low-maintenance solution that meets both the chemical compatibility needs of caustic liquor and the environmental durability demands of remote WA mining conditions.
