The conceptual processing flowsheet that is being tested consists of beneficiation stages to generate a titanium-rich heavy mineral concentrate and to remove acid-consuming gangue minerals, followed by a simple acid leaching stage, and will therefore not require an energy intensive, on-site smelting process.
Potential On-site High Value TiO2 Products
The final product from the leaching stage is expected to be a fine precipitated powder with a high TiO? concentration, approaching the same content as natural rutile (>95%). However, the material will likely require calcination and pelletisation to make it an attractive, handleable product for customers. Based on Q4 2023 rutile market supply and demand forecasts the price range for rutile is in the order of US$1,880/t to US$2,180/t, reflecting a tightening of the supply chain despite increasing demand over the next decade (Source: Sovereign Metals Ltd. February 2024 Investor Presentation - Prices per TZMI; Ilmenite price: November 2023 FOB Mozambique; Rutile price: "weighted average price for bagged rutile shipments").
The Company could additionally consider a further on-site refinement step for the TiO2 product and make a pigment-quality product for marketing directly to end users, in the manufacture of paints and coatings, plastics and paper. Based on Q4 2022 prices the expected price range for TiO2 pigments is in the order of US$4,340/t to US$5,180/t.
